The processor platform will come enable six-channels DDR4 (384-bit wide controller, up-to DDR4-2666), and a new 100G OmniPath interconnect.
The Omni-Path Interconnect is a fiber-optic technology with bandwidth starting at 100 Gbps. The Omni-path controller will be codenamed "Storm Lake." A new 10.4 GT/s UPI interconnect will maintain communication and each socket will get three UPI channels.
Purley will support 8 processor sockets and will come with 'Cannonlake' graphics and media transcode, QuickAssist encryption and compression offloads and FPGA integration. The PCH is designed under code-name Lewisburg and it will ship with new 10G Ethernet controllers.
Purley will be the basis for 14nm processors running up-to 28 physical CPU cores, with HyperThreading enabled. This means that we are talking about up to 56 logical CPUs. The TDP is 45W up-to 165W depending on the processor model, and Socket P is the new socket to use.
