Intel Diamond Rapids will support PCIe 6.0, and CXL 3.0
According to the previously compiled news, after Intel’s next-generation Xeon scalable processor Sapphire Rapids, the next will be Emerald Rapids, Granite Rapids, and Diamond Rapids. Sapphire Rapids, which was originally scheduled to ship in 2021, has been delayed many times, and it has been postponed to the 6th to the 9th week in 2023, which also directly affects the release plan of Intel’s subsequent Xeon scalable processors. Emerald Rapids’ schedule is also rumored to be moved backward.

Recently, Twitter user @yuuki_ans revealed that Intel Granite Rapids will support eight-channel DDR5 memory, PCIe 5.0, and CXL 2.0. It is rumored that the Granite Rapids is based on the Intel 4 process (the original 7nm EUV process), uses the Redwood Cove architecture core, and provides 128 PCIe lanes. Its single SoC contains multiple chiplets, packaged through EMIB, and there will also be HBM versions and Rambo Cache chips.
It has been reported in the past that, starting with Granite Rapids, Intel’s Scalable Xeon server processors will feature the latest AVX-1024/FMA3 to improve performance across a variety of workloads, though that could mean an increase in power.
At the same time, Granite Rapids will use the new Mountain Stream platform and maintain compatibility with the next generation of products.
Intel hasn’t revealed much about Diamond Rapids, not even a codename, or a specific timeline. The leaked information this time indicates that Diamond Rapids also supports eight-channel DDR5 memory, as well as PCIe 6.0 and CXL 3.0, and there will also be an HBM version.
Since the CXL 3.0 specification was only released in August of this year, it will take at least three years to appear in the Xeon Scalable processor lineup. It is rumored that Diamond Rapids will use the Intel 3 process (the original 5nm process) and use the Lion Cove architecture core.
