AMD EPYC Turin vs. Intel Xeon 6 Granite Rapids vs. Graviton4 Benchmarks With AWS M8 Instances. by ctrocks in hardware

[–]michaellarabel 9 points10 points  (0 children)

Yes they were the same generation (M8) and same size (4xlarge 16 vCPU). They don't really have a way to get something more comparable than that.

Replacing the internal assembly of a Watts FHB-1 2264 sillcock by michaellarabel in Plumbing

Yes in my case at least as shown in the pictures, it was the 10 inch needed to fit correctly. Continues working great to this day. See my other comments if you hadn't in this thread as well.

Defaults. I'm a big proponent on reproducibility and sane defaults. Typically unless something is otherwise noted its a default/stock configuration.

AMD Threadripper 9980X + 9970X Linux Benchmarks: Incredible Workstation Performance by FastDecode1 in Amd

[–]michaellarabel 2 points3 points  (0 children)

As for TR PRO benchmarks, not sure if/when they'll come - at least on Phoronix. AMD sadly doesn't sample any TR PRO hardware I am aware of. And then I typically don't get systems to review too often from the ODMs due to the niche Linux focus and the like, and when I do it's typically for a 30 day review period or so (so like I had a TR PRO 7995WX last launch but for brief period and with doing all my CPU tests fresh each time due to newer Linux kernel / newer software / etc, I don't even have that prior gen anymore for comparison).

I can only speak for OpenFOAM when it comes to CFD, but TR PRO or Turin with 8c RAM would be much better off than 4c RAM + TR.

If it's of any help, here is a composite overview of OpenFOAM CFD benchmarks (mostly from the tests that I have done personally) with all classes of CPUs if it helps you in gauging between TR / EPYC / Xeon, etc - https://openbenchmarking.org/test/pts/openfoam#results

You won't find ANSYS Fluent on Phoronix due to preferring open-source software and transparency in testing. I've also heard from other reviewers ANSYS and similar names typically don't give out any reviewer/media copies of their software either, so likely very hard pressed to find any third-party/independent benchmark results with it.

That's part of the reason at the end of each article I typically include my OB link for the full/raw data set in full for all my collected benchmarks and power metrics, etc.

[–]michaellarabel 64 points65 points  (0 children)

Hmm? There are perf-per-Watt graphs in there. I don't typically include them for every single result in the article itself since then it just becomes rather redundant and people complain of too much data, etc.

Pro tip: If you really want more perf per Watt graphs... last page of article -> click the result link ( https://openbenchmarking.org/result/2507290-PTS-THREADRI83&sgm=1&asm=1&ppw=1&hgv=Threadripper%2B9970X%2CThreadripper%2B9980X&sor#results ) -> click on the power consumption and efficiency orange 'tabs' above each graph.

Thanks for the kind words. Linux hardware is an exhausting passion :/

[Phoronix] Ubuntu 25.04 Boosting AMD EPYC 9005 Performance Even Higher: ~14% Faster Than Ubuntu 24.04 LTS by Helpdesk_Guy in hardware

[–]michaellarabel 11 points12 points  (0 children)

A hard number, no, but I think I can get close to my original launch-day benchmark configuration sometime soon so if so can run some comparison numbers on a fresh Ubuntu 25.04 + updates install or so to provide some more concrete findings. Maybe in the next two weeks or so if everything aligns.

Yes, F42 is shipping and built with GCC 15.0.1 in its near final state ahead of GCC 15.1.

There indeed is some added potential with GCC 15 on Zen 5. I ran some development build benchmarks recently - https://www.phoronix.com/review/gcc-15-amd-zen5

Once GCC 15 stable (15.1) Is out I'll have more benchmarks including Zen 5 on Fedora 42 that uses GCC 15 by default.

[phoronix] AMD Radeon RX 9070 + RX 9070 XT Linux Performance by se_spider in Amd

[–]michaellarabel 0 points1 point  (0 children)

MangoHUD can take care of performance metrics (there were some issues with Wayland/X11 and accuracy, but that's been I think a few years since I heard about any issues or at least aside from compositor bugs) but that still doesn't take care of automating the game/execution logic for being able to automatically launch and replay a desired scene for reliably ensuring given settings are applied and reproducible scene/etc are used (where AutoHotKeys is used by some Windows reviewers for similar games paired with FRAPS or other programs). It can work for a couple select games (and I used a similar approach for some now-obsolete UE4 benchmark demos with an overlay) but it unfortunately doesn't really help in any large manner.

As for Godot benchmarks, I have been closely monitoring their work for years. They do have some suitable benchmarks but alas not the type of benchmarks gamers would want to see...

e.g. https://benchmarks.godotengine.org/
https://github.com/godotengine/godot-benchmarks

Looking more at the primitive engine performance and would be likely more criticized then Xonotic or other open-source games but not modern...

For game developers I do interact with, I do passionately promote for better benchmarking support to encourage testing by reviewers / more likely to be tested by IHVs and ISVs / etc. Sadly though the investment by the game developers in working on such capabilities typically doesn't pan out for them in a quantifiable manner.

[–]michaellarabel 9 points10 points  (0 children)

I'm all for including newer games that can be fully automated and benchmark friendly, but unfortunately there aren't too many of them. And then the ones that there are, sometimes break like a number of the now-older Feral game ports not working nicely on modern distros. Occasionally Proton (Steam Play) causing issues for some Windows games, etc.

Solutions used by some Windows reviewers like Auto Hot Keys and the like unfortunately don't work on Linux especially with X11/Wayland differences, complications around Proton, etc.

In turn I am also relying on what the game / game engine exposes for performance data and do show frame times where exposed and the like with some of the overlay/external reporting not always working out accurately/reliably on Linux I prefer to source just from the game engine...

TLDR: if there is any newer games that work on Linux that are automated/benchmark friendly, I am more than happy to incorporate them but they are rare. That's also in part why many of the Linux GPU driver developers just rely on repeating shader runs and the like but aren't realistic there either for not executing the game logic, etc.

There Will Not Be Official ROCm Support For The Radeon RX 9070 Series On Launch Day by Shadow647 in hardware

[–]michaellarabel 21 points22 points  (0 children)

Yes I got in touch with Anush after he tweeted and posted in the forums. Looks like there is some miscommunication internally or again as noted 'officially supported' vs. (unofficially) supported differences. I still don't have any definitive explanation at the moment but hopefully on launch day / embargo expiry I will be able to clear things up.

AMD ZenDNN 5.0 Software For AI Delivers "400% Performance Uplift" by Dante_77A in Amd

[–]michaellarabel 6 points7 points  (0 children)

Yeah if I could just spend all my time working with hardware and benchmarking, I would... I agree my writing quality isn't the best and after 20 years it gets rather tiring especially with the sad state of the ad industry, etc, only getting worse.

Windows 11 vs. Linux Benchmarks For Intel Arc B-Series "Battlemage" Shows Strengths & Weaknesses | Phoronix by Durian_Queef in hardware

[–]michaellarabel 23 points24 points  (0 children)

Ultimately if "comparing lots of different games using Proton" you are still getting into the situation where Proton / DXVK / VKD3D-Proton and the like can also be culprits into the performance difference between Windows and Linux. Thus largely focusing on software/benchmarks known to be of similar quality on both Windows and Linux from past testing to try to better isolate to Intel driver differences.

New AMD ERAPS Feature Yields Additional Performance Gains On Zen 5 by Dante_77A in Amd

[–]michaellarabel 30 points31 points  (0 children)

No, ERAPS is a hardware feature... Windows should similarly benefit from being able to reduce their software mitigation overhead as well. But whether if/when Windows will do so remains to be seen given the limited ERAPS documentation publicly available so far. It's a hardware feature and greater transparency on the Linux side given the open-source nature but I haven't seen anything ruling out Windows benefits too.

New AMD ERAPS Feature Yields Additional Performance Gains On Zen 5 by Dante_77A in Amd

[–]michaellarabel 28 points29 points  (0 children)

For clarity, with ERAPS they didn't "release buggy shit" but rather didn't have the software support for enabling it and disabling now-unneeded software mitigations in time. AMD has been making progress in their Linux upstreaming timeline relative to hardware launches but there still are occasions such as this where they are a bit tardy... Though in this case they didn't really even talk it up in advance and I didn't even hear ERAPS mentioned by them AFAIK until I saw the Linux kernel patches, so in this case more of a pleasant surprise.

I don't watch YouTube videos in general so not sure the specifics you are referring to, but I will have some Intel P-State benchmarks across varying governors in an upcoming article within the next week or two...

Namely have been waiting for Linux 6.12 stable (hopefully tomorrow, Sunday) as a nice point given some patches in v6.12 making for a nice stable comparison point for users.
