Thanks to the leaked slides obtained by @InstLatX64, we have more details and some performance estimates about Intel's upcoming 5th Generation Xeon "Emerald Rapids" CPUs, boasting a significant performance leap over its predecessors. Leading the Emerald Rapids family is the top-end SKU, the Xeon 8592+, which features 64 cores and 128 threads, backed by a massive 480 MB L3 cache pool. The upcoming lineup shifts from a 4-tile to a 2-tile design to minimize latency and improve performance. The design utilizes the P-Core architecture under the Raptor Cove ISA and promises up to 40% faster performance than the current 4th Generation "Sapphire Rapids" CPUs in AI applications utilizing Intel AMX engine. Each chiplet has 35 cores, three of which are disabled, and each tile has two DDR5-5600 MT/s memory controllers, which operate two memory channels each and translating that into eight-channel design. There are three PCIe controllers per die, making it six in total.
Newer protocols and AI accelerators also back the upcoming lineup. Now, the Emerald Rapids family supports the Compute Express Link (CXL) Types 1/2/3 in addition to up to 80 PCIe Gen 5 lanes and enhanced Intel Ultra Path Interconnect (UPI). There are four UPI controllers spread over two dies. Moreover, features like the four on-die Intel Accelerator Engines, optimized power mode, and up to 17% improvement in general-purpose workloads make it seem like a big step up from the current generation. Much of this technology is found on the existing Sapphire Rapids SKUs, with the new generation enhancing the AI processing capability further. You can see the die configuration below. The 5th Generation Emerald Rapids designs are supposed to be official on December 14th, just a few days away.
