Processor options
The SN850 supports the Intel Xeon Processor Scalable Family options that are listed in the following table.
The server supports two or four processors. When four processors are installed, they are connected in the
Mesh topology to maximize inter-processor communication (requires processors with three UPI
connections).
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
Intel Turbo Boost Technology 2.0
Intel Advanced Vector Extensions 512 (AVX-512)
Intel Ultra Path Interconnect (UPI) links at 10.4 GT/s (replaces QPI)
Depending on the processor model installed, the processors are connected together using either two or
three UPI links. Processors with a T suffix are those that have more robust thermal characteristics (higher
T-case). Processors with an M suffix support support greater than 768 GB per processor.
Note: The SN850 processor part numbers listed include two processors.
