alt Hacker NewsThe H100 has 16,000 cuda cores at 1.2ghz. My rough calculation is it can handle 230k concurrent calculations. Whereas a 192 core avx512 chip (assuming it calculates on 16 bit data) can handle 6k concurrent calculations at 4x the frequency. So, about a 10x difference just on compute, not to mention that memory is an even stronger advantage for GPUs.
A Zen 5 core has four parallel AVX-512 execution units, so it should be able to execute 128 16-bit operations in parallel, or over 24k on 192 cores. However I think the 192-core processors use the compact variant core Zen 5c, and I'm not sure if Zen 5c is quite as capable as the full Zen 5 core.
