Hey guys, to clear up Signature vs foundation:
-Signature will have 2-3c better performance over Foundation in XOC scenarios. In everyday usage, the performance is very similar.
-All our blocks use the same cold plate, including the upcoming GPU. (Though threadripper will use the XL version of our cold plate)
-The Signature performs better because there is zero flex in the block, not necessarily because it acts as a heatsink. It's possible some extra heat is wicked away by the block, but the real performance has to do with the precision of the compression of the CPU to the cold plate.
-The profile of the Signature internals and structure is different and tailored specifically for the latest "tall" consumer and HEDT Intel CPUs. While the Foundation is slightly different for more general performance.
-The latest gen of CPUs are weird, results can vary quite a bit depending on tim spread, tightening, etc (as JPM found).
-So not super surprising to see strange individual core counts on 18 core CPU. There are so, so, so many variables in XOC situations, especially with latest CPUs.
