On both my old 8 core Ryzen and my newer 3900X Zen easily beats MuQSS kernels in FPS Phoronix: Early Linux 6. Newsletter. First, the Ryzen 7 1800X is an absolute beast of a CPU. But the zen kernel follows the latest stable kernel release. 10 Kernel Features So Far: AMD Zen, TBM3, More ARM Linux Kernel : 2016-12-16: Early Independent Benchmarks Of The MuQSS Scheduler Linux Kernel : If you really want to benchmark, I suggest taking a look at the linux-nitrous-fire kernel which is performance-oriented. sched_latency_ns kernel. Fans ran Arch Linux has five different officially supported kernel builds: stable, hardened, long-term. As for gaming specifically, you might wanna look over some user benchmarks for any games you play on the FlightlessMango website (FlightlessMango is the The Linux kernel in use was the Linux 2. Every other update it would break, forcing me to revert and Linux 4. Zen 5 is the first AMD architecture with an entire AVX-512 pipeline featuring Then install the kernel plus its headers: sudo pacman -S linux-zen linux-zen-headers. Below is an overview of the generalized performance for components where there is sufficient statistically significant data based upon user-uploaded results. 4. The Ryzen AI 9 365 could compile the Linux kernel in around the same time as the Ryzen 7 7840HS. November was filled with interesting Linux benchmarks ranging from the Apple M4 testing kicking off to ongoing AMD Zen 5 benchmarks both On AMD Zen 4 CPUs, acc1 and acc2 execute on ports 2 and 3, while acc3 and acc4 run on ports 0 and 1. Unfortunately, the $360 price tag is steep, and there are several good alternatives available. Zen kernel works for me . In the case of the ASKAP HPC benchmark, the Ryzen 7 5800X3D with 3D V-Cache remained the front-runner. 0 Phoronix: Apple M4, More AMD Zen 5 Benchmarks & Linux Kernel Drama From November November was filled with interesting Linux benchmarks ranging from the Apple M4 testing kicking off to ongoing AMD Zen 5 benchmarks both for desktops and servers, a lot of exciting upstream kernel activity (and some drama), and more. 0-25-generic (the current default Ubuntu 17. Written by Michael Larabel in Processors on 6 July 2023 at 06:00 PM EDT. Phoronix: Early Linux 6. For the environment, I used an AWS m7a. However, vecLib bests the MKL on smaller matrices, often by a wide margin. 0 on various CPUs following that updated LLVM compiler stack release earlier this year. Initial Benchmarks Of The AMD AOCC 5. The task was simple, we have a standard configuration file, the Linux 4. If Intel's kernel is faster than the open alternative, then Intel is doing AMD a favor, even if they're not doing the absolutely best job they possibly could. The first one is the zen kernel, but the second one is a ck kernel build for zen processors, nothing to do with the zen kernel. Different kernels do things differently to fill different needs, whether it be thread scheduling, I/O access, etc. php?page=news_item&px=Arch-Linux-Zen-Kernel-Tests It can be hard to say, but try the standard kernel and the custom kernel and benchmark the workloads you care about. In our review we saw good gains with PBO overclocking and TDP increases. The Ryzen AI 9 HX 370 was delivering great uplift over Zen 4 and extending the While using stock kernel , My laptop hangs or freezes many times during heavy workloads. The main two caveats at this point are needing a recent kernel/Mesa if wanting to make use of the iGPU Radeon graphics (along with linux-firmware. phoronix. Phoronix had some benchmarks that I will try to test with my custom kernel, after I rebuilt it with znver3. 2 kernel from kernel. Doom Eternal and Cyberpunk 2077 run with the same fps and performance/stability on both the zen and vanilla kernel on my system. Distros with a more conservative release cycle tend to use these for their releases. which config is better would be a matter of testing on your system but personally i would recommened the xanmod kernel based on phoronix benchmarks So i’ve been running Kernel zen1-1-zen for some time now. Kernel 3 used the menu config option for Processor family = AMD Zen 3 or Intel Haswell or Intel Alder Lake; The make test. When on a patched Linux kernel with the ERAPS code applied and on a supported processor, as part of the "spectre_v2" mitigation reporting it will indicate "ERAPS hardware RSB flush" as active. I did not want to start from a blank slate, and I also did not want to use any kernel-git packages, prefer a stable kernel release for a daily use system. 6 System Platform: Linux 5. 10. * Use eselect news read to view new items. OpenBenchmarking.

With GCC 10 released earlier this month, we have begun our benchmarking of this annual feature release to the GNU Compiler Collection. real-time, and Zen, but which of these is the fastest for desktop Arch Linux users? Here are some fresh benchmarks looking at the performance out of these different kernel build options for Arch Linux and its derivatives. The 5-level paging kernel-side bits were upstreamed back in Linux 4. The mission at Phoronix since 2004 has centered around enriching the Linux hardware experience. Even Apple M4, More AMD Zen 5 Benchmarks & Linux Kernel Drama From November Phoronix : 2024-12-01: Linux 6. 12 was recently promoted to being this year's Long Term Support (LTS) kernel with it being the last major kernel release of 2024. 12 in 2017 and enabled by default since 2019 with Linux 5. Being Zen 4, AVX-512 is supported and in turn works for testing both x86-64-v3 and x86-64-v4 repositories. 12 merge window wrapping up this weekend and the bulk of the new feature merges now in the tree, I've begun running some Linux 6. On heavily multi-threaded use the zen kernel starts working better. Let's talk about the various different available Kernels and what the be On the software side a range of Linux kernel activity also captivated readers. The only real difference is the scheduler. a notable example of an "unready patch" was the NTFS driver from paragon. There is no zen kernel for LTS. At the end of last year I pointed out that the early Linux 5. Copy the name of the module and replace Fedora 37 Native Kernel vs. Here are those benchmark results CachyOS calls out the use of the CacULE CPU scheduler as one of its differences compared to the stock Arch Linux kernel. IMO, this is more on AMD than Intel. As such there are a few Phoronix articles today looking at these Zen 4 processors under Linux and many benchmarks whole several more follow-up articles will be coming over the weeks ahead. etc. First up is a look at the GCC 9 vs. 8 Jan 12:32. 11 Is Now Looking Great For AMD Zen 2 / Zen 3 Performance Processors : 2021-01-21: XanMod's Linux 5. 14 Is Up To Around 23.

Below is a look at the most popular reviews and the most popular news for Q3. In my opinion if you ever feel the necessity to use a RT kernel then The "zen" patch that gets applied on top of the normal kernel source does have MuQSS in it but with the default configuration of the package, the compiled kernel still uses the CFS scheduler like the normal linux kernel package. The zen kernel, where compared to the default gaming there was no increase in performance, and the liquorix which instead was unstable enough to not be able to play the games that I could play with the zen kernel or by default. org metrics for this test profile configuration based on 2,375 public results since 13 March 2024 with the latest data as of 19 January 2025. 10 with a Linux 6. 5. Liquorix Kernel. LLVM Clang 10 compiler OBSOLETE, NEW WEBSITE. 10 and in other hardware/software configurations -- both for future Phoronix articles and also just running more benchmarks to explore more areas of these new AMD CPUs. Kernel benchmarks like those on phoronix are mostly useless because they measure “throughput”, while most custom kernels targeting the desktop are Enthusiast kernel optimized for low latency. The CachyOS desktop is a themed version of KDE Plasma 5. This kernel with Zen patches was used during all of our file-system testing. 33-rc7 kernel and to provide the Reiser4 file-system support we had installed the Zen-kernel. The LTS kernels are a branch of the Linux kernel, designated by upstream to receive a longer than usual support window, often several years vs a few months for a normal kernel. You could optimize a kernel to give you maximum performance in benchmarks and it might make your desktop less responsive in general use. AMD Schedutil vs. AMD's Zen 4 line-up including the Ryzen 7000 Due to my lone AMD EPYC 9004 "Genoa" server at the moment being busy running other benchmarks, this round of Zen 4 AOCC benchmarking was done using an AMD Ryzen 9 7950X desktop processor. From the benchmarks about to be shown, AMD's initial AVX-512 implementation is promising and has me all the more excited for finding it on AMD EPYC "Genoa" processors. 13 for that kernel debuting by late January, AMD customers once again have a lot to look forward to from new Zen 5 features being enabled to additional performance optimizations. omano 4 March 2021 17:01 5. 0 To 5. Discussion. Meanwhile the Ryzen AI 9 HX 370 as the fastest at compiling the Linux kernel was consuming only 24 Watts with a peak of 33 Watts! Huge improvement to the power The Zen 2 results come in as a bit of a surprise. 8 carries some elements of Zen 5 CPU support, more upstream Linux enablement for the next-generation AMD processors remains ongoing. There is a less recent and less in-depth article here comparing Zen to Vanilla. Phoronix: Benchmarks Of Arch Linux's Zen Kernel Flavor Following the recent Linux kernel tests of Liquorix and other scheduler discussions (and more), some requests from premium supporters rolled in for seeing the performance of Arch Linux's Zen kernel package against the generic kernel. But to HPC customers they can show that Intel CPUs are faster. Stay tuned for more Linux 6. The thing to do if you want to be sure is run the phoronix test suite or a particular gaming benchmark and see what you come up with. 12 Features Are Super Exciting With Real-Time, Sched_ext, Intel Xe2 Here are our first 5th Gen AMD EPYC Turin benchmarks in looking at the EPYC 9575F, EPYC 9755, and EPYC 9965 processors across many workloads and testing in both single and dual socket configurations. 1 May 16:12. The only benchmark I could find is a phoronix test comparing archlinux vanilla and zen kernels 5. 0 Compiler On 5th Gen EPYC. 4 and found the gaming performance to be rather disappointing for that kernel flavor derived from the "Zen" patches and more. 21 Sep 13:27. Edit: I have installed the Liquorix kernel, it has been excellent. They still beat OpenBLAS et al. Damentz, the maintainer of the Liquorix patchset, is a developer for the Zen patchset as well. The Linux kernel may move to unconditionally enabling 5-level paging support for x86_64 kernel builds. I found this gentoo wiki page, with instructions on compiling the kernel for Zen arch CPUs. The Arch Zen kernel doesn't use MuQSS, just CFS with optimized settings. We are using a third party service to manage I tried testing two kernels on EOS. Get plenty of data points. 70GHz (32 Cores / 64 Threads), Motherboard: ASUS ROG ZENITH II EXTREME (0601 BIOS), Chipset: AMD Starship/Matisse, Memory: 64512MB, Disk: 1000GB Force MP600, Graphics: AMD Radeon VII 16GB (1802/1001MHz), Audio: AMD Timed Linux Kernel Compilation 6. With 2024 in the books, here is a look back at the most popular Linux hardware reviews and benchmark articles for 2024. thats because i am using 4gb ram laptop . It also enables more upstream kernel hardening features than Linux. If you're worried about the mainline getting "bloated" (which is not a thing you should be worried about), Zen is even worse by your own metric. From a resort in Texas, AMD just announced their initial Ryzen 7000 series line-up as the highly anticipated Zen 4 desktop processors as well as touching ever so lightly on Zen 4 based AMD EPYC 'Genoa' and teasing RDNA3 graphics Zen-kernel is a modified linux kernel with some out of box config changes and patches. Last week I shared some initial numbers how surprisingly when disabling Zen 4 CPU security mitigations can actually *hurt* the Ryzen 7000 series CPU performance. Below is an overview of the generalized performance for components where there is sufficient statistically significant data based upon user-uploaded The Liquorix kernel continues to be a bit more unique and among its alterations compared to a generic kernel is Zen interactive tuning, making use of the MuQSS process scheduler, hard kernel preemption, For these tests were benchmarks of 4. Mostly because of some points written here List of benefits that Zen offers · Issue #30 · zen-kernel/zen-kernel · GitHub While not having specific issues, some crashes/slowdowns and hangs are happening here and there and i like to try stuff. sched_wakeup_granularity_ns And the factors that are used are these here (the number stops increasing after more than 8 CPUs): cpus The review embargo just lifted for the AMD Ryzen 7000 series "Zen 4" desktop processors ahead of their retail availability this week. Liquorix vs. Zen can be installed with the command. Linux 6. 13 PCI: AMD Enables PCIe TPH For Zen 5 Servers, Intel Adds In total I ran 333 benchmarks across the Ryzen 9 7900X, Ryzen 9 7950X, and other tested comparison parts. 17 and a premium patron requested some fresh benchmark results. New AMD ERAPS Feature Yields Additional Performance Gains On Zen 5. 0 Zen Kernel Zen1 FPS: 215. Fortunately, the Zen kernel patches now include a fix that should make their gaming performance more competitive. 5 kernel. In addition to the three thousand original Linux/open-source news articles last year, there was 191 Linux hardware reviews / multi-page benchmark articles written by myself. Here are the specs: CPU: Intel i5-10210U (8) @ 4. And I like it. Since AMD Ryzen 7 1800X Python Linux Kernel Compile Benchmark. The downside is that other processes Zen kernel is a set of patches on top of the mainline. 7-zip Compression Performance. With zen kernel I can still use the computer while compiling. 13 AMD : 2024-11-25: AMD Bus Lock Trap Support Merged For Linux 6. 10 and the Linux 6. 15 LTS Fio is an advanced disk benchmark that depends upon the kernel's AIO access library. The main issue with it right now is that it's experimental and not well tested, yet, so you can try it if you want but you'd have to wait a few days until everything is working as expected (binaries aren't released yet either). The main advantage I find from custom kernels is responsiveness/multitasking under load rather than raw performance numbers. Older No idea at the moment what scheduler the "zen" jernels use. gz | grep ZEN CONFIG_ZEN_INTERACTIVE=y # CONFIG_MZEN is not set. Code: emerge --ask sys-kernel/zen-sources * IMPORTANT: 7 news items need reading for repository 'gentoo'. Liquorix employs the MuQSS scheduler, Zen interactive tuning, a 1000Hz tick rate, hard kernel preemption, BFQ for the I/O scheduler, and other tweaks. XanMod vs. I used the zen kernel for a while. Then I reinstalled everything, since I didn’t have anything important on the PC. All the assumptions for ANOVA are met: Having one Zen 4 and one Zen 4C core enabled led to a 30 Watt average (32 Watt peak) while compiling the Linux kernel compared to two Zen 4 cores leading to a 34 Watt average and 36 Watt peak. 2 compiler and other stock packages. This one we had a little bit of fun with. sudo pacman -S linux-zen Afterwards be sure to boot from it during startup! ¶ Hardened kernel. The past two weeks I have been eagerly running many benchmarks of AMD Zen 5 on Linux with Strix Point via the Ryzen AI 9 365 and Ryzen AI 9 HX 370 with great results. For this Ryzen 9 7950X desktop going from Linux 5. 6 patch-set; KSM patch for proper working of uksmd daemon from pf; Memory management tweaks from zen-kernel (MGLRU, Compaction, Watermark) With Zen 4 you can still boot the kernel with mitigations=off to disable the SSB, Spectre V1, and Spectre V2 mitigations applied while leaving the system in a "vulnerable" state. Last Thursday AMD finally sent out the basic enablement patch for AMD Zen 4 "znver4" with the GCC compiler. OpenBLAS (with VORTEX/ ARMV8 kernel) vs Veclib vs MKL vs OpenBLAS (ZEN kernel) With large matrices, MKL on the Ryzen significantly outperforms vecLib on the M1. 7 Score: 5435 Min FPS: 27. 10 Kernel Features So Far: AMD Zen, TBM3, More ARM Linux Kernel : 2016-12-16: Early Independent Benchmarks Of The MuQSS Scheduler Linux Kernel : When running various Java benchmarks against the CachyOS-supplied OpenJDK packages, there was a slight uptick in the x86-64-v4 packages. The Ryzen AI 9 365 has two less Zen 5C cores than the Ryzen AI 9 HX 370 but equates to a build time just a few seconds slower. OpenJDK Java workloads, database workloads, web browser tests, and No one has the time to compile the kernel every minor patch, but for the people that want every percent out of their system, then it's pretty solid. If someone has a good kernel-centric benchmark, I am interested to see a controlled comparison. Performance benchmarks of Arch Linux Kernels Zen Benchmark. 5 Max FPS: 420. The code is compiled with GCC 14. Let's see how CachyOS This are my results Maybe do some maps and repeat Mostly better lows on Tkg-BMQ MOBO b350gaming3 OS: Garuda Linux DE: Plasma 5. Page 4 of 22. 14. Afaik, Zen kernel based on Liquorix with additional tweaks, but I can't find any relevant comparisons of these two. Look at all the Phoronix benchmark, or other independent benchmarks. Dabbling with a few HPC benchmarks on the AMD Ryzen 9 7900 series has me all the more excited for EPYC "Genoa" processors. 11 Different kernels are hard to benchmark in a practical way. In both instances I have noticed less input lag and have seen in benchmarks less stutters compared to linux-zen on Arch. They can however be measured by benchmarking tools. Liquorix is an enthusiast Linux kernel designed for uncompromised responsiveness in interactive systems, enabling low latency compute in A/V production, and reduced frame time deviations in games. Phoronix's testing confirms that AMD has a very performant and highly power-efficient AVX-512 implementation in Zen 5. Designed for desktop, multimedia, and gaming workloads, it is often used as a Debian Linux performance replacement kernel. Because every benchmark seems to favour zen kernel over You can try some artificial benchmarks, like running kernel compilation and cyclic test, or trying to open some big file in something, start chrome and measure time etc. Liquorix for those out of the loop is a configured and patched kernel intended to deliver an optimal experience for desktop, multimedia, and The problem with benchmarks will always be to choose what types of loads you test. Borderlands 3: 45min So I figure it's better not to be GPU bound for testing different schedulers and kernels because I would be testing the CPU. Before it was patched CFS. While during the development stages of AMD Ryzen 7 7840U Performance Benchmarks On Linux: Great Uplift For Zen 4 Laptops. Take for instance the Linux kernel build performance, x265 Using an optimized kernel improves performance. The zen kernel actually has a 3% advantage in the tested games. Latest & improved ZSTD 1. That being said, there have been many benchmarks over the years that show that custom kernels at the very least do slightly improve average framerate. 10 vs. Following the EPYC 7763 benchmarks I will have more AMD INVLPGB Linux benchmarks in the new year when having more time for testing and trying out the patched kernel on an increased range of hardware. Zen is a great generic performance kernel, while linux-tkg is more of a build system for various patches, cpu schedulers, and optimizations for a kernel. The Zen 2 equipped model featured a Ryzen 7 4700U 8-core processor with 8 cores, 8 threads, 8MB of L3 Some people install zen kernel for anbox support I believe. Written by Michael Larabel in Processors on 28 July 2024 at 09:00 AM EDT. You have to configure the kernel and compile it yourself if you want to use MuQSS. in benchmarks, even on Zen. these patches are often ones unapproved by mainstream either for them being "unready" on unsafe. Written by Michael Larabel in Processors on 26 September 2022 at 09:00 AM EDT. 200GHz GPU: CometLake-U GT2 (integrated UHD Graphics) Memory: 5388MiB / 7716MiB See more Arch Linux has five different officially supported kernel builds: stable, hardened, long-term. I have terrible habit of opening far more browser tabs in the course of a day than anyone ever should and I Default Garuda kernel, up to date with current repos. AMD Ryzen 7 1700X Python Linux Kernel Compile Benchmarks. //EDIT: another source for benchmarks kernel benchmark Linux 6. 13 kernel cycle is the AMD P-State driver to be used by default with the new EPYC 9005 series processors. That's a xanmod kernel built with -O3 and -march=znver2 being beaten out by a kernel with no such optimizations, though I have no idea how much difference those optimizations actually make anyway Of course this is an synthetic benchmark, and I can't tell the difference by eye anyway, but I'd rather not leave performance on the table TBH. The effects of optimization are often difficult to judge. Processor: AMD Ryzen Threadripper 3970X 32-Core @ 3. This is why I switched to the linux-tkg kernel some time ago. I use ZEN Kernel mainly due to 2 reasons: a) everything works (like for mainline) and maybe there is some minor benefit compared to mainline AMD's Ryzen 7000 "Zen 4" CPUs are shown to feature better performance with Spectre V2 mitigations kept enabled. Benchmarking. cfg. We are expressing results in terms of complies per hour to make the results easier to read. We delivered many benchmarks of Clang 10. real-time, and Zen, but which of these is the fastest for desktop Arch Linux users? Here are some fresh benchmarks looking at the Following the recent Linux kernel tests of Liquorix and other scheduler discussions (and more), some requests from premium supporters rolled in for seeing the performance of Phoronix often runs kernel benchmarks. git as of this month!) and then the Raphael audio driver is only appearing in Linux 6. Even if Phoronix Test Suite is fine to highlight differences between different kernel revisions you can't use it yourself to prove your kernel performs better for your own load because you don't ask it the same operations on a day to day basis. For Zen 3 and Zen 4 though the kernel-only mitigation solution is also available in the event your system doesn't yet have updated firmware/microcode. 6. Next, regenerate your Grub configuration: sudo grub-mkconfig -o /boot/grub/grub. Contribute to zen-kernel/zen-kernel development by creating an account on GitHub. Zen+ Benchmarks. AMD Ryzen 9 7900X / Ryzen 9 7950X Benchmarks Show Impressive Zen 4 Linux Performance. 21. My hypothesis would be that something is wrong with the i/o scheduler (disk, not cpu), because waiting on i/o has a tendency to block entire processes. Ryzen 5 4500U Scientific Workloads And More. The zen kernel is in the official repositories and is as well supported as the vanilla kernel. 69 Comments. sched_min_granularity_ns kernel. then the Ryzen 7 1700 may be the better option as we surmised in AMD Ryzen 7 1700 Linux Benchmarks – The Zen you should buy. AMD EPYC 9004 Genoa Linux Kernel Compile Benchmark. I've done a few benchmarks on my system, and even run linux-zen for a while (6 or so months), and I can confirm it has a slight performance benefit, ranging from 1-2%, but frankly I don't think it's worth the hassle, especially if you depend on out-of-tree drivers, like nvidia, etc. AMD Zen 5 on Linux easily dominated the list of most popular This weekend I posted some fresh benchmarks of the Liquorix kernel against upstream Linux 5. That was fun, but now with Zen 5 desktop processors in I used Zen on Arch. . Ready modules for binary kernel builds can be found in the repository. AMD Ryzen 7 1700 Python Driven Linux Kernel Compile Benchmark Arch Linux has five different officially supported kernel builds: stable, hardened, long-term. 12 Git with all the default mitigations and then repeated the benchmarks on Linux 6. Enabling one Zen 4C core led to the CPU power consumption average going up by just three Watts. But from my experience, this kernel has a higher average CPU frequency when no apps are running in the background, which could negatively impact the battery. People wonder which Linux Kernel is best to use to boost performance on your system. All three laptops have 16GB of dual channel memory and NVMe storage and were cleanly loaded with Ubuntu 23. Xanmod gaming kernel benchmarks by Michael Larabel for a future article. If you are unsure just use the default kernel, if you want to you can benchmark it against zen, but its unlikely to see a big difference. 12 Kernel Benchmarks Showing Some Nice Gains On AMD Zen 5 With the Linux 6. Now I use kernel-tkg with BORE scheduler (before it was patched CFS, now it's the new eevdf also patched). Phoronix recently had an article on that If you want to get into schedulers PDS is supposed to reduce input lag, at the cost of potential stuttering For Zen 3 and Zen 4 processors AMD is in the process of rolling out new microcode while for Zen 1 / Zen 2 there is simply a kernel-based mitigation needed. 10 kernel with KPTI patched), 4. Kernel replacement built using Debian-targeted configuration and the Zen kernel sources. Learn more via the OpenBenchmarking. Reply reply -Luciddream- • The last time I had a reason was when I was running a pre-Polaris AMD graphics card not supported by the in-kernel driver I just found a comment on the zen-kernel which confirms my suspicions, so I guess I Not only is the AMD 'CPU frequency invariance regression' from that new support with the in-development Linux 5. There was only 1 title where I experienced worse performance in benchmarks compared to the Zen kernel, and that was Cyberpunk 2077. Of the many new features in Linux 6. 5. Linux 4. Generally, linux-zen is a good option. I will boot into cachyos-bore and check for intel_pstate sadly this benchmark is really worse in benchmarking kernels directly in the detail, its okay if you want to compare the windows performance with your linux performance of your rig, but actually it The changes I made between the two benchmarks are as follows: I enabled SMV (AMD-V) in bios. 8 Build: defconfig. 6. It really depends on the workloads and your exact system. The 16-core Zen 4 desktop CPU was running Ubuntu 22. if you have some good amount of ram , you may not able to see the perfomance improvement.

I enabled "Memory Integrety" in Windows 11 I enabled "Kernel-mode Hardware-enforced Stack Protection" in Windows 11 The difference in performance are as follows (first figure pre enabling of VBS second figure post enabling of VBS): Stemming from last weeks Linux kernel patches suggesting an -O3 experimental option for all CPU architectures and Linus Torvalds rather quickly shooting it down, here are some fresh benchmarks looking at the Linux kernel performance when the kernel image is rebuilt with the -O3 optimization level rather than -O2. The Linux-focused review outlet used four generations of Lenovo Thinkpad laptops for testing. compound-optimisation-test. At this point I see custom "performance" kernels like Zen, Liquorix etc as simple snake oil They were useful in the past when ESync/FSync wasn't implemented in the mainline kernel, but nowadays they only add extra potential points of failure compared to the mainline kernel imo. For comparing Vanilla Linux vs Liquorix, this recent Phoronix article compares many versions of the Linux kernel in a wide variety of benchmarks. 12-rc1 kernel release expected on Sunday. to my knowledge zen and lqx are the same kernel but with different configurations. GNOME Shell 48 Alpha Introduces Screen Time / Health Breaks, Mutter 48 Alpha Out Too With the zen kernel my cpu load can be just as high but I can still change desktops and windows. While as of today this -march=znver4 support has been merged into GCC 13. 12. While many route to the mitigations=off approach to avoid the performance penalties attributed to the different mitigations, in the case of AMD Zen 4 on the Ryzen 9 Arch Linux based CachyOS has released their 'July 2024' release that also introduces an AMD Zen 4 optimized repository that caters to current Ryzen 7000/8000 and EPYC 4004/8004/9004 (Zen 4) procssors and Standard kernel scheduler gets higher throughput for most tasks. You can install a second kernel and The stable Arch Linux kernel was basically tied with the Zen kernel performance followed by the hardened kernel. What matters is how the kernels work for you. 26 at present. A security-focused Linux kernel applying a set of hardening patches to mitigate kernel and userspace exploits. The RocksDB embeddable persistent key-value store was showing some real-world benefits from the AMD ERAPS patched kernel on this Zen 5 server by avoiding the explicit RET stuffing/filling on context switches. org test page. Vanilla on servers all day though. So it's not worth using the zen kernel if you don't even notice a difference. AMD posted the various JSON files needed for the PMU events for various It's been a while since last benchmarking the Liquorix kernel that is a modified version of the Linux kernel. navjack27. PD: Also for gaming, the zen kernel includes the Valve fsync patches Reply reply [deleted] • Comment deleted by user So in the end, other people's benchmarks (especially if measuring only fps) have a somewhat limited use. This will be a long-ish post. 2 on Ubuntu 24. I have been running zen for years and I have had no problems. Compare your own system(s) to this result file with the Phoronix Test Suite by running the command: phoronix-test-suite benchmark 2001094-PTS-LIQUORIX33 The Liquorix kernel continues to tweak its Linux kernel configuration and add in extra patches for aiming to optimize the kernel for gaming/desktop-type workloads. With these EPYC Turin CPUs the AMD P-State "active" mode is the default. What are your benchmarks going to be? Or do you just want Zen because somebody told you it was better? That said, experiment with it. Since the initial reviews on Phoronix I continue running more benchmarks on the AMD Zen 3 CPUs on Ubuntu 20. Phoronix - review Motivated in part by the recent le9 kernel patches that are already carried by XanMod and not having benchmarked the XanMod or Liquorix Linux kernel downstreams in a while, here are some fresh benchmarks of Liquorix Is linux-zen still the best kernel to use? Or are we missing out on even better kernels? I want to suggest that we should have a thread pinned in the forum for discussing different kernels, where anyone can share their experiences and benchmarks about the different kernels they use. AMD EPYC 7642 Linux 5. Liquorix was recently updated against Linux 4. 2 Million Lines Of Code Linux Kernel : The New Linux 4. 13-rc1 Released With Many New Features Linux Kernel : 2024-12-01: Apple M4, More AMD Zen 5 Benchmarks & Linux Kernel Drama From November Phoronix : 2024-12-01: Linux 6. Zen Interactive Tuning: Tunes the kernel for responsiveness at the cost of Arch Linux Kernels Zen Benchmark. On my nicer laptop with 32G of memory I don't notice much of a difference. Sent out this morning were the initial patches around AMD Zen 5 performance monitoring and events for the perf subsystem. Then I have a zen kernel built for zen processors, so that is called "arch-zen-custom" because "arch-zen-zen" would sound odd. 12 benchmarks on different Intel and AMD systems following the Linux 6. real-time, and Zen, but which of these is the fastest for desktop Arch Linux users? The zen kernel is supposed to increase responsiveness at a small cost in power usage and overall performance, so this was unexpected. Queued up this week via the tip/tip. I was already loving the Ryzen 7000 series Across dozens of different workloads the Ryzen AI 9 HX 370 was a very interesting Zen 5/5C processor both in raw performance and especially for performance-per-Watt.

To remove zen kernel from modules, we'll cd into that directory and list the contents: cd /lib/modules && ls -a. across nearly 400 benchmarks these new Zen 5 desktop CPUs impress, and these new Zen 5 desktop processors are priced competitively. 5 WM: KWin WM Theme: Sweet-Dark Terminal: konsole CPU: AMD Apple M4, More AMD Zen 5 Benchmarks & Linux Kernel Drama From November. Or the AMD Ryzen 9 7950X can achieve a default Linux kernel build in just under 40 seconds! The Ryzen 9 5950X meanwhile took one minute. (Image Credits: Phoronix) In Spectre V1, from a Linux 6. For example, I have "arch-zen" but also "arch-ck-zen". zen-kernel was distributing it before the Linux kernel was. However, the default kernel can be tweaked as shown in certain parts of this article to perform better. 8 on a threadripper cpu. The CFS config changes and the 1000 Hz clock are nice from my point of view. org patches that provide Reiser4 support and other features. Reply reply I use the Zen kernel, because claims are it tightens up timings a bit, which I figure may help with real-time video conference recording and streaming, and other multimedia intensive tasks. Heres an example with the zen kernel albeit now out-of-date. Below is an overview of the generalized performance for components where there is sufficient statistically significant data based upon user-uploaded The AMD Ryzen 7 9700X boasts a robust eight-core design and exceptional single-threaded performance with great power efficiency. The main difference between zen and nitrous is that nitrous is compiled using clang 10 See all the benchmarks in full from this Linux kernel comparison on the Ryzen 5 5500U laptop over on OpenBenchmarking. 0 perspective, Spectre V1 Support for building NVIDIA modules with some patches. 13 PCI: AMD Enables PCIe TPH For Zen 5 Servers, Intel Adds PCIe Cooling Driver Hardware : 2024-11-25: New AMD Zen 5 Perf Events Going Into Linux 6. Reply reply PostgreSQL benchmark: Docker versus native There is no "benchmark a kernel", there is "benchmark this specific task given this specific scenario with these specific criteria". 13-041413-generic as You can see a significant difference in the benchmarks of linux-amd. With zen I can saturate 16C/32T at 80-100% and still have a very responsive desktop, but when testing network and disk speed I It turns out EPYC Turin / Zen 5 does contain enhancements to its design for benefiting AMD P-State usage. For those enterprise Linux users, hyperscalers, and others typically jumping from one annual LTS kernel to the next, in this holiday article are some benchmarks looking at the performance benefits of Linux 6. 13 AMD : 2024-11-22 Right now I am booted into stock Garuda zen kernel while obtaining the results above. org metrics for this test profile configuration based on 2,332 public results since 13 March 2024 with the latest data as of 8 January 2025. metal-48xlarge instance with 192 cores across 2 sockets. Timed Linux Kernel Compilation 6. Unigine Heaven Benchmark 4. The zen kernel prioritizes the processes that you interact with directly, giving you the illusion that your machine is running faster. Like this one we had some time before: Kernel Benchmarking Results - Zen, $ zcat /proc/config. 11 vs. 1 Git kernel build. In any event nice seeing these gains that benefit going back to Zen 3 albeit a bit surprising that the Linux kernel wasn't pursuing AMD INVLPGB for broadcast TLB invalidation until now. Featured Kernel Comparison.
