The Intel Xeon Platinum 8460Y+ is a server processor with 40 cores, released in 2023. It is part of the Xeon Platinum lineup, using the Xeon Scalable platform, and fits the LGA4677 socket. Internally, it is built on the "Sapphire Rapids" architecture. Thanks to Intel Hyper-Threading, each core can handle two instruction streams simultaneously, yielding a total of 80 threads for improved parallelism. The Xeon Platinum 8460Y+ has a base clock of 2 GHz and can boost up to 3.7 GHz depending on workload and thermal headroom. Intel manufactures the "Sapphire Rapids" silicon on a Intel 7 process node. This processor supports DDR5 memory across 8 channels, up to 4TB total, with ECC support standard for data integrity in server workloads. It supports both single-socket (1P) and dual-socket (2P) configurations, with 80 lanes of PCIe 5.0 available for storage, networking and accelerators. With a TDP of 300W, the Xeon Platinum 8460Y+ runs hot and requires a capable cooling setup. The cache hierarchy consists of no dedicated of L1, no dedicated of L2, and 105MB of L3 cache — a substantial cache pool well suited to memory-bound enterprise and virtualization workloads.
4th Gen Xeon Scalable 'Sapphire Rapids' — Intel's first Xeon generation with DDR5, PCIe 5.0, and on-die AMX AI acceleration.
