Intel "Sapphire Rapids" Brings PCIe Gen 5 and DDR5 to the Data-Center
As if the mother of all ironies, prior to its effective death-sentence dealt
by the U.S. Department of Commerce,
Huawei's server business developed an ambitious product roadmap
for its Fusion Server family, aligning with
Intel's enterprise processor roadmap.
It describes in great detail the key features of these processors,
such as core-counts, platform, and I/O.
The "Sapphire Rapids" processor will introduce the biggest I/O
advancements in close to a decade, when it releases sometime in 2021.

2021Q1那時DDR5(4800??)跟PCIE 5.0一起上

2020Q2上市的Icelake就支援PCIE 4.0，但是隔年Q1就上5.0
唉! LGA1200是最後一代DDR4&PCIe 4.0平台
