(initial comment deleted since one part addressed integer 'lanes' instead of the 32-bit FP that's more directly relevant in a comparison with a GPU, and the other part was incorrect.)
- vardump 7y ago> They have 16 SIMD registers. AVX-512 has 32 SIMD registers.
- jcranmer 7y agoI'm counting the number of single-precision FP units. Although, strictly speaking, AVX-512 hardware actually has two FMA units per core.
- vardump 7y agoI thought AVX-512 ALU resources varied between models?
- jcranmer 7y agoThis is Skylake server part (which should be implied by the high core count), which is using this block diagram: https://www.researchgate.net/figure/Skylake-Microarchitecture-CPU-Core-Block-Diagram-6_fig5_332543387 https://www.researchgate.net/figure/Skylake-Microarchitectur...
