Thanks to CTOnews.com netizens Wu Yanzu in South China for the delivery of clues! CTOnews.com Sept. 6, according to the latest tweets released by YuuKi_AnS on the X (Twitter) platform, share the relevant specifications of Intel's fifth-generation "Emerald Rapids", sixth-generation "Granite Rapids" Xeon processors, and Raptor Lake Refresh processors.

Intel's fifth-generation "Emerald Rapids" Xeon processor message says that Intel's fifth-generation Xeon (Xeon) processor is code-named "Emerald Rapids", which is suitable for data centers and is equivalent to Raptor Lake on the desktop side.

From a micro-architecture point of view, Emerald Rapids uses the Raptor Cove core and Intel 7 process nodes. The IPC improvement of Raptor Cove is lower than that of Golden Cove, and the expected performance improvement is not significant.

Emerald Rapids will provide 64 cores and 128 threads, 320MB cache, support DDR5-5600 memory, up to 80 PCIe Gen5 channels. CTOnews.com Note: most of the samples are now in the final stages of production and should be on shelves in the fourth quarter of 2023.

The sixth generation "Granite Rapids" Xeon processor Granite Rapids is the trump card against AMD Genoa, labeled "ES1", indicating that it is in the early stage of development and can be equipped with up to 56 cores.

The SP model has 2 Compute Tiles with a total of 80 or 88 P cores, and there should be 3 Compute Tiles versions with a total of 120 or 132 P cores supporting 8-channel DDR5-6400 memory.

Granite Rapids is expected to launch in the first half of 2024.

The Sierra ForestSierra Forest E-Core series is similar to Granite Rapids and is based on Intel 3 process, with up to 144cores, but it should be noted that these are efficiency cores, and two versions of SKU have been found so far.

The Sierra Forest will be available with 96core, 128core and 144core versions and support DDR5-5600 memory. These CPU support dual motherboard configuration, theoretically up to 288cores. Because SMT is disabled, each core will get only one thread.

All processors below the Raptor Lake Refreshi5-14600 reduce the supported memory speed from 5600 MT/s to 4800 MT/s. Because all CPU are in the qualification stage.
