No AVX 512 in the new ones ... or old ones. Personally I wouldn't let it be a buy decision There isn't much in BOINC that can use 512.
isn't AVX-512 Intel exclusive?
Only because AMD chose not to implement it yet
The article linked earlier shows the AMD AVX2 performance is about equal to intel AVX-512. And this is on a test that usually favors intel.
When y'all upgrade let me know and I'll take that obsolete hardware off your hands.
And hide it in the closet with the rest of your gear that takes the summers off...
