AVX-512 in GB6.3 is almost useless.

Please before jumping to conclusions wait for @Hail The Brain Slug to get back to us: both of his runs seem to have been with AVX2 only.

Here are the two runs without the compare feature.

I think the AVX2 executable of GB has the AVX-512 codepath built into it. There isn't a separate binary for that.

Don't disable AVX-512 from UEFI. Keep it on.

Instead, go into the GB6 folder from CMD using CD /D folder_path

Then run geekbench6.exe (not the one with a space between letter h and 6).

Then run geekbench AVX2 exe.

Let's compare those scores.

That’s an interesting idea, though it will also remove AVX2 codepath.

Benchmark results for a Gigabyte Technology Co., Ltd. X670E AORUS XTREME with an AMD Ryzen 9 7950X processor.

A run from geekbench6.exe with AVX512 left enabled. Directly comparable to
AVX512 enabled,. standard run : https://browser.geekbench.com/v6/cpu/6830619
AVX512 disabled, standard run: https://browser.geekbench.com/v6/cpu/6830875

Seems like AVX in general has virtually no bearing on scores. Excellent to see they just included it to check a box and nothing more.

Sorry, my mistake. Geekbench6.exe is the AVX2 one. The x64 one doesn't have AVX.

HWINFO shows AVX512 support disabled when I disable it in the UEFI, so I can only assume the UEFI disable works correctly and there is indeed no meaningful change in score without it.

That's not what @igor_kavinski and I found on Intel chips. Without access to any Ryzen 4 machine, I can't check what's going on.

Yes, but I also showed some Ryzen 3 vs Ryzen 4 results with large outliers that might indicate AVX-512 benefits. I'd need access to a Ryzen 4 machine to run tools to count instruction categories usage to understand what @Hail The Brain Slug found.
Click to expand...

Yeah, I’d say the Ryzen 3 to 4 results indicate as much but the AVX512 on/off results pretty strongly refute that conclusion. Can Zen 4 support AVX-VNNI (non 512 version)? That could explain the discrepancy. I didn’t think Zen 4 had support for it, but maybe?

I think I've verified the UEFI AVX512 disable works. Passmark 11 uses AVX512 in the CPU Extended Instructions test. I did 3 runs with it enabled and disabled. Note, Passmark says the fallback in this case is FMA, not AVX2.

After some Google'ing and some Linux perf play, I found out that geekbench_x86_64 still uses AVX2 instructions.

Beware with Geekbench v6 results! | Theldus's blog

AVX-512 instructions are used in both cases, while the number of AVX2 instructions is reduced, but they are still in use:

Code: 
perf stat -e cycles:u,instructions:u,fp_arith_inst_retired.512b_packed_single:u,fp_arith_inst_retired.256b_packed_single:u,fp_arith_inst_retired.512b_packed_double:u,fp_arith_inst_reti\

I will let @Hail The Brain Slug post his own results, both with AVX-512 disabled and enabled at BIOS level.
