Intel · Xeon Gold · 2023 · LGA4677
The Intel Xeon Gold 5418Y is a server processor with 24 cores, released in 2023 at an MSRP of $1,483. It is part of the Xeon Gold 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 48 threads for improved parallelism. The Xeon Gold 5418Y has a base clock of 2 GHz and can boost up to 3.8 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 185W, the Xeon Gold 5418Y runs hot and requires a capable cooling setup. The cache hierarchy consists of no dedicated of L1, no dedicated of L2, and 45MB of L3 cache.
4th Gen Xeon Scalable 'Sapphire Rapids' — Intel's first Xeon generation with DDR5, PCIe 5.0, and on-die AMX AI acceleration.
