10nm for desktop based chips are still on the roadmap, at least Intel debunked that somewhat, however newly leaked slide confirms a thing or two more in the server market as well, including 10nm server processors based on Ice Lake.
A slide originating from Asus lists a number of product characteristics and launch data for Xeons processors. As you can see Cascade Lake products will be succeeded by Cooper Lake in the second quarter of 2020, and here we see Ice Lake-Xeons will arrive in the third quarter. Cooper Lake will fit on the new Socket P + and get a TDP of up to 300 watts. It is striking that the number of cores per socket has doubled to 48 cores, while a maximum of two sockets can fit on one motherboard.
The number of pcie 3.0 lanes has been increased from 48 to 64 lanes (Gen4 for Ice Lake), and the number of interconnects per processor has also increased to 4. The ram now has eight memory channels via ddr4-3200 instead of six channels with a maximum of ddr4-2666. Ice Lake will get the same Socket P + platform, but the tdp has been lowered to 270 watts per processor. The number of calculation cores is also slightly lower with 38 cores and 72 threads, the number of sockets per motherboard is two equal to Cooper Lake. The number of memory channels is equal to Cooper Lake, but there is support for the second generation of Intel's 'persistent memory', or Optane.
