Questions about the upcoming platform Intel Hedt are still more than answers. Officially, Intel has not yet mentioned its Sapphire Rapids-X series, but its launch is unofficially expected at the end of this year, perhaps about the third quarter.
According to recent notes to the AIDA64 patch, Intel can develop a series of 12-year-generation processors "ALDER LAKE-X", presumably based on the same 16-nuclear silicon as the LGA1700 series.
Thus, the future Xeon / Hedt platform can be divided into the Sapphire Rapids and Alder Lake series. SAPPHIRE RAPIDS-X is the long-awaited successor to Cascade Lake-X, and it will be primarily focused on the workstation market, and not on the game systems for enthusiasts. In this regard, Intel will follow the path of AMD ThreaDripper, which is now concentrated on the Pro series. The Alder Lake-X series can be considered the successor of the Kaby Lake-X series, released in 2017 along with SkyLake-X.
There are rumors that from the point of view of specifications, Sapphire Rapids is divided into two series: High-class workstations and workstations of mass demand. The first can have more cores and support for 8-channel ECC memory, as well as 112 PCIE GEN5 lines. It is expected that in the main series there will be no support for EEC, and support for PCIE lines will be limited 64. In addition, at least two SPR matrices are discussed: XCC (Xtreme Core Count matrix) with 56 cores and HCC / MCC (High Core Count) with uncertain The number of cores. It can be assumed that the ALDER LAKE-X will be part of the main platform of workstations by filling out the space in the "low-core" processor segment.
In addition, since Intel eliminated the support of the AVX-512 instructions from the SKU Core series "S", it can be assumed that the "X" series can return this feature. And Sapphire Rapids-X, and Alder Lake-X should be part of the future Intel Fishhawk platform.
