At their Architecture Day 2020, Intel also confirmed the launch of its upcoming Sapphire Rapids CPU platform in 2021. Sapphire Rapids will feature support for DDR5 memory and PCIe 5.0 and will truly be a "next-generation" data center chip with the addition of the CXL 1.1 interconnect. The company has also plans to release the OneAPI (going gold) later this year which should tie up their master plan of a unified datacenter ecosystem quite nicely.

While the company did not reveal the exact process Saphire Rapids is based on, we can infer that it will likely be based on the company's 10nm SuperFin Enhanced process because it succeeds Ice Lake processors (which are based on vanilla 10nm) and because it uses TME. Total Memory Encryption is an architectural design that encrypts the memory completely so even if someone dumps the RAM - they would just get garbage data. This feature is also present in Tiger Lake - which is based on 10nm SuperFin - which lends credence to Sapphire Rapids being based on the same (or more advanced) process as well.
