I like that they seemed to include a stability test for Zen2 CPUs, but I am not sure if there's a need for a vendor specific benchmark... unable to be compared to Intel, AMD's competitor.

the benchmark could measure things that intel does not have. latency between chiplets or whatever. It does not have to be power measurement or a speed index of some sort for all the cpu. Also consider this is pretty normal considering not all cpus have same instruction sets, avx, avx2, sse4.1 and sse4.

I wonder if it means that developers have to utilize their software/engines for Zen2.

Feiry does ASM level optimizations for each cpu, so in all fairness, aida's benchmarks are only valid between the same generation of cpu's.

If you want ideal performance, thats pretty much true for every CPU - especially those that change their SIMD behavior. And in the case of Zen2, they are expanding their AVX/AVX2 SIMD to operate on full 256-bit, like Intel, instead of the 128-bit engine that Zen/Zen+ had.

Retired SHA1

finally, it was meaningless with todays CPUs having built-in extensions..
