Intel will be >doubling the core counts of its Xeon Scalable processors over the next two generations, courtesy of advanced process and packaging technologies. The 4th Gen Sapphire Rapids-SP lineup will be the first Xeon server family to leverage a chiplet/tiled design, pushing the counts to 60 for the first time. The succeeding Emerald Rapids and Granite Rapids families will continue to focus on compute density, doubling the number of compute dies at the high end.
Emerald Rapids will allegedly pack 64 high-performance Redwood Cove cores across four compute tiles, retaining the Intel 7 node. Unfortunately, the 5th Gen Xeon Scalable processors have been delayed until late 2023, or so MLID claims. This put it just a few months before the Granite Rapids launch.
Granite Rapids will be the big one. Straight up doubling the core count to 128, it’ll be Intel’s most exciting enterprise platform in over a decade. It’ll leverage the Redwood Cove+ P-core, a minor refinement over the vanilla Redwood design. In addition to the denser compute, Granite will adopt the server-centric Intel 3 process node for better performance per mm2.
Granite Rapids-SP is slated to land in the first half of 2024 alongside AMD’s Turin family. Unfortunately for Intel, these Epyc CPUs will squeeze in as many 256 cores (512 threads) into a single socket design. Team Red is expected to pack up to 16 CCDs on the next-gen SP5 socket to achieve this feat. In addition to 256-core parts, we’ll also get 192-core SKUs.
