Intel & JEDEC have pointed out DDR5-8800 memory capabilities for next-gen servers such as Xeon 6 "Granite Rapids" CPUs with up to 128 cores.
Intel Granite Rapids "Xeon 6" CPUs Are Running DDR5 Memory At Speeds of Up To 8800 MT/s Which Is Part of Updated JEDEC Specs For Next-Gen Servers A few days ago, JEDEC published its new JESD79-5C DDR5 SDRAM standard which mainly focuses on elevating the performance and security features of next-gen server platforms.
The main high-lights of the standard include the expansion of timing parameters definition from 6800 Mbps to a staggering 8800 Mbps speed.

The reveal comes from Intel's recent Meta Llama 3 benchmarks in which the company tested its Granite Rapids "Xeon 6" CPU. Although the information regarding the SKU is not mentioned, it is mentioned in the footnotes that the chip features 120 P-Cores based on the Redwood Cove core architecture and 240 threads (HT On).
The platform was a 2S configuration so you are looking at two 120-core chips for a total of 240 cores and 480 threads. Based
