A few users might be confused about the Platinum 8156, a quad core part at $7007. This is a high cache/core part, offering 4.125 MB of L3 per core, up from 1.375MB per core for the standard parts. Intel has offered these parts for a few generations now, for customers that find their code to be L3 sensitive or have licensing agreements base on per-core/per-socket as well. What customers will have to note is that Skylake-SP has a different L3 cache compared to previous generations, by being a non-inclusive cache (and essentially a victim cache) means it will be used very differently. With a larger L2 cache as well, the L3 might become less important, or the fact it becomes a victim cache might make it useful/useless on the code. For customers after these sorts of cores, it is worth profiling the code on the CPU first, just to make sure.
