Where are you getting that? I thought Intel was at 180 physical integers registers for the same core microarchitecture shared by both desktops and servers.

- baybal2 5y agoThe number of "hidden" registers for register renaming is few times that number.
- Symmetry 5y agoThe last I heard about the number of physical integer registers changing at Intel was the increase from 168 to 180 with Skylake. https://en.wikichip.org/wiki/intel/microarchitectures/skylake_(client) https://en.wikichip.org/wiki/intel/microarchitectures/skylak... If you have a source I'm happy to read it but otherwise I think you're confused. Especially about Intel client and server cores having different numbers of registers. The lowest level difference between them I've heard of that wasn't features being fused off is different L3 cache sizes.
- stephencanon 5y agoYeah, all the public documents I've seen say the Sunny Cove PRF has no change from Skylake, so 180 INT registers and 168 FP.
- baybal2 5y agoI think I am confused. I do remember I heard that physical register file was around 500 registers, but I believe my memory fails me now.
