> Moreover, that bad review has not tested the domains where Zen 5 has up to double performance when compared to any previous desktop CPU, like floating-point computations, cryptography or ML/AI. These use cases alone are a good enough reason for upgrades for many of those who use such CPUs for professional purposes and not for games.
I hope AVX512 dies a painful death, and that AMD starts fixing real problems instead of trying to provide magic instructions to then create benchmarks that they can look good on.
Because absolutely nobody cares outside of benchmarks.
The same is largely true of AVX512 now - and in the future. Yes, you can find things that care. No, those things don't sell machines in the big picture.
I hope AMD gets back to basics: gets their design process working again, and concentrate more on regular code that isn't HPC or some other pointless special case.
I want my power limits to be reached with regular integer code, not with some AVX512 power virus that takes away top frequency (because people ended up using it for memcpy!) and takes away cores (because those useless garbage units take up space).
Stop with the special-case garbage, and make all the core common stuff that everybody cares about run as well as you humanly can. Then do a FPU that is barely good enough on the side, and people will be happy. AVX2 is much more than enough.
