supports up to two processors.
All supported processors have the following characteristics:
14 nm process technology
Six DDR4 memory channels
48 PCIe 3.0 I/O lanes
1 MB L2 cache
1.375 MB L3 cache per core (except where larger, as noted with ** in the table below)
Intel Hyper-Threading Technology (except Bronze processors)
Intel Turbo Boost Technology 2.0 (except Bronze processors)
Intel Advanced Vector Extensions 512 (AVX-512)
Two Intel Ultra Path Interconnect (UPI) links at up to 10.4 GT/s (replaces QPI)
