> Alder Lake has its AVX-512 disabled
Alder lake has AVX-512 disabled because 512 bit data paths on atom cores don't make sense and Microsoft couldn't execute on a IHV specific scheduling change so quickly. AVX2+ and later Windows scheduler changes will take care of this. Just like P-states, Intel now has hardware scheduling hints for the OS as well.

Because arrow lake is tracking closely within 6 months and MTL/LNL are focused on the platform power efficiency.

It very much has to do with process nodes as well, with tight coupling of process to chip area (yield, thermals) and number of transistors.
- bee_rider 3y agoAVX-512 on atom is cool, KNL was a good idea. I get that they aren’t making these chips for me, but Alder lake with AVX-512 would have been so cool, it would be like having a Phi in the same package as your main cores. I’m not sure what exactly killed the Phi, but not having to talk through PCIe might have given them a chance to keep up with the inevitable march of NVIDIA Tesla bandwidth improvements.
