Which CPU option on the iMac Pro gives you two FMAs? I know for Skylake X you need a 61xx or better CPU to get two FMAs, but it’s not clear what the situation is with Skylake W ? Everything I have found for Skylake W just says “up to two FMAs”, without any specific detail as to which CPUs have 1 and which have 2?
Only a few low-end 4 core Skylake W CPUs are limited to one FMA. Even the entry-level iMac Pro has an 8 core CPU, so it would appear that all iMac Pro configurations will have two FMAs.
