> It costs a lot of area for something that's doesn't move the needle for the majority of desktop applications But that could be a bit of a chicken and egg sit

  Absolutely. It's useful in text processing, it's useful in emulation, it's useful for doing bit-math for various encodings and checksumming, etc. The newer revisions don't have any downclocking either. https://old.reddit.com/r/emulation/comments/lzfpz5/what_are_the_implications_of_avx512_for_emulation/ https://old.reddit.com/r/emulation/comments/lzfpz5/what_are_... https://travisdowns.github.io/blog/2020/08/19/icl-avx512-freq.html https://travisdowns.github.io/blog/2020/08/19/icl-avx512-fre... People have made some incredibly broad assertions about the technology as a whole on the basis of a first-gen product that lingered on the market for far too long because of the 10nm woes. People also hang on Linus's words far, far too much. He's incredibly toxic and willing to opine about stuff he's been disconnected from for 20 years. Lisa Su is putting her money where her mouth is, AMD is making a billion-dollar bet on AVX-512 at a time when Intel has actually abandoned it in the consumer market entirely. Maybe she's doing it just for the server market, but that still means she thinks server-market customers are going to see an actual benefit on normal server tasks, such that it will be worth making every single customer pay more for a larger piece of silicon. It's not the kind of thing you do "just to win a couple HPC benchmarks". Sorry, I trust the person with the financial stake in this discussion a lot more than I trust Linus's spit-takes.
