The M1 is a very different chip from traditional x86. It only has 128 bit vectors, which can be a major bottleneck in software that is perfectly vectorized, but it also has way more out of order execution and decode bandwidth.
- kllrnohj 4y agoThis Ryzen only has 256 bit vectors, though, it's not like the avx512 monsters that Intel randomly pushes. And in specfp2017 the M1 was overall stronger than even a 5950X ( https://www.anandtech.com/show/16252/mac-mini-apple-m1-tested/4 https://www.anandtech.com/show/16252/mac-mini-apple-m1-teste... ). It was specint2017 where it fell behind, almost the reverse of what you'd expect.
