I gave it a go. And yup, I see a definite improvement: it jumped from 1,583,326,242 bytes/sec to 2,376,741,703 bytes/sec on my Intel laptop using AVX2. A 50% improvement! I also *think* I'm seeing a 10% improvement in ARM using NEON. On my DE10-Nano board, BLAKE3 portable gets about 50mb/sec, and now BLAKE3 using NEON gets about 55mb/sec. (Roughly.) I might have goofed up on the old benchmarks though, or just not written down the final correct numbers. I observed no statistically significant performance change in the no-SIMD builds on Intel and ARM. p.s. in my previous comment with that table of benchmarks I said "mb/sec". I meant "bytes/sec".
