Now that we've covered both ends of hyperbole, it's maybe worth noting that a lot of CPU parallel tasks can be well accelerated by ISPC, which can make reasonably effective use of AVX512 (with the aforementioned clock speed caveat): https://www.mail-archive.com/ispc-users@googlegroups.com/msg... Also, AVX512 is a much nicer (orthogonal) ISA than SSE or AVX2. While there are some niche applications that need larger amounts of memory than GPUs can offer, it's worth noting that this speedup comes from making the CPU act more like a GPU, and they aren't as fast as GPUs acting like GPUs (which are essentially many 32-wide vector units, rather than AVX512's 16-wide). |
