#dotnet #AVX512 code gen is unfortunately not great in the face of masks which Sep uses heavily. This means AVX-512 is slower than AVX2 
cc @tannergooding can this be improved?
PS: While I understand the arguments for not having explicit mask types in dotnet I still think it will never be great, since it will be an endless whack-a-mole around code gen... compared to letting devs be able to do what they want.
#AMD #Ryzen9000 vs. #Intel #CoreUltra #ArrowLake On #Linux For Q1-2025 In ~400 Benchmarks
In cases where #AVX512 can be utilized, the Ryzen 9000 series is the definitive winner over the Intel Core Ultra Series 2 desktop processors. In some HPC applications the Core Ultra 9 285K with 24 physical cores does well in scenarios where SMP isn't leveraged.
Overall the #Zen5 based #Ryzen9 #9950X straight-up won 50% of the time with a first place finish.

The Compelling #AVX512 Performance Advantage On #AMD #EPYC 9005 "Turin"
Workloads tested on this #EPYC9655 Supermicro server, with AVX-512 yielded 1.57x the performance of the same hardware/software but with AVX-512 forced off.

How many xmm/ymm/zmm registers did x86 have vs. x86-64? I'm seeing conflicting information on Google, claiming that x86 had zmm0-zmm31 while others claim it only had up to xmm15/ymm15/zmm15. (This might be because some webpages are confusing x86-64 in 32bit mode as being the same as the x86 architecture proper.)
GNU Coreutils 9.6: A Leap Forward with Enhanced Performance and POSIX Compliance

#FFmpeg devs boast of up to 94x performance boost after implementing handwritten #AVX512 assembly code
The developers have created an optimized code path using the AVX-512 instruction set to accelerate specific functions within the FFmpeg multimedia processing library. By leveraging AVX-512, they were able to achieve significant performance improvements -- from three to 94 times faster -- compared to standard implementations.

Klingt zu gut um generalisierbar wahr zu sein, ich vermute dahinter letztlich einen von Intel finanzierten Image-Stunt.

#Intel #CoreUltra 9 285K "#ArrowLake" Delivers Strong #Linux Performance Review
Power efficiency improvements with Arrow Lake are real. Core Ultra 9 285K on average was at 136W, right inline with 137W Ryzen 9 9950X and much lower than 156W average with the Core i9 14900K. Core Ultra 9 285K was very competitive but if running a lot of #AVX512 workloads and areas where Zen 5 was delivering striking wins, Ryzen 9 9950X and the ~$429 Ryzen 9 9900X can deliver great value.
