Intel Granite Rapids and Sierra Forest will support 12-channel DDR5 and have a TDP of up to 500W

In January of this year, Intel released the fourth generation Xeon scalable processor, Sapphire Rapids. According to previous reports, Emerald Rapids, which also belongs to the Eagle Stream platform, will be released in the fourth quarter of this year and will use the Raptor Cove architecture core, providing up to 64 cores and 128 threads, but still manufactured using Intel 7 process technology.

The real transformation will come with Granite Rapids, which will use the Mountain Stream and Birch Stream platforms, the latter of which is used for high-end Xeon chips. Recently, YuuKi_AnS released information on the Avenue City reference platform motherboard, which belongs to the Birch Stream platform and uses a new LGA-7529 socket that can support processors with a TDP of up to 500W, which will be used in Granite Rapids as well as the energy-efficient core-only Sierra Forest.

The motherboard measures 16.7 x 20 inches with a 20-layer PCB, has 24 DDR5 DIMM slots supporting 12 memory channels, and can achieve a 6400 Mbps speed for 1DPC and an 8000 Mbps speed for MCR; 6 PCIe 5.0 x16 links and 6×24 UPI links.

In addition, the motherboard also provides two PCIe x2 M.2 slots, one PCIe x2 M.2 (2280) module, and one PCIe x1 LOM (Springville), and has a large number of I/O interfaces, such as rear USB 3.0+USB 2.0, USB Type-C, Mini DP, Gigabit Ethernet, RunBCM module (AST2600), as well as TPM 2.0, SPI TOM module and PFR 4.0, etc.

Intel will make significant changes to Granite Rapids, which will be based on Intel 3 process technology, use the Redwood Cove architecture core, and increase the number of cores and threads to 128 cores and 256 threads. Its base frequency is 2.5 GHz and provides 128 PCIe 5.0 channels. Intel has revealed that Granite Rapids will contain multiple small chips in a single SoC, which will be packaged with EMIB and will also provide a version with integrated HBM memory.
