Intel LGA-7529 socket exposure, Granite Rapids package area may increase by 70%
Intel released its fourth-generation Xeon Scalable processors, code-named Sapphire Rapids, last month. Emerald Rapids, which also belongs to the Eagle Stream platform, may be launched within this year, but the real qualitative change is Granite Rapids and the new Mountain Stream (or Birch Stream) platform, and the Sierra Forest equipped with an energy-efficient core will also use the same platform.
Recently, Twitter user @SkyJuice60 exposed a new Intel LGA-7529 socket, which will be the new socket used by Granite Rapids and Sierra Forest. Compared with the LGA-4667 socket currently used by Sapphire Rapids, it is obviously much larger, and the pins have increased by 61%. It is estimated that the packaging area of the chip is 105 × 70.5 mm, which means an increase of 70% compared to the existing Xeon products.
Intel will make major changes to Granite Rapids, which will be based on the Intel 3 process, use the Redwood Cove architecture core, and increase the number of cores and threads. It is rumored that it will reach 128 cores and 256 threads, and the L3 cache will be 240MB. Its base clock is 2.5 GHz, providing 128 PCIe 5.0 lanes and 12-channel DDR5 memory. Intel has revealed that Granite Rapids will contain multiple small chips in a single SoC, packaged through EMIB, and will also have HBM and Rambo cache chips.
Unlike Granite Rapids, Sierra Forest is all equipped with smaller power-efficient cores. It can have up to 334 cores and is also manufactured using the Intel 3 process, supporting 12-channel DDR5 memory and PCIe 5.0. It is understood that Intel may also develop some special versions, but there is less relevant information. It is rumored that Intel will have a similar product code-named Clearwater Forest in the future to succeed Sierra Forest.
