I think the Top500 benchmark is biased here. It’s a supercomputing benchmark which means it’s going to heavily weight SIMD and float64 performance, which are things that rarely matter for everyday computing. SIMD has uses in the real world - image or video editing, data crunching, graphics. But consumers basically never use fp64 any more, and so many modern chips have next to zero performance on them. That could easily skew the numbers in intel’s favor.

I run a number of other benchmarks for a better comparison (linked from my blog post: https://github.com/geerlingguy/sbc-reviews/issues/111).

The Intel chip holds its own for multicore in less bursty workloads, where the fans help.

They do in audio processing. ;)

What? Pretty much every general-purpose calculation on your computer that isn’t an integer is done with FP64. AI may not use it and games may prefer FP32 for many things, but your CPU certainly does a ton of FP64 work.
