Intel · Xeon Gold · 2021 · LGA4189
The Intel Xeon Gold 5318Y is a server processor with 24 cores, released in 2021 at an MSRP of $1,273. It is part of the Xeon Gold lineup, using the Xeon Scalable platform, and fits the LGA4189 socket. Internally, it is built on the "Ice Lake-SP" 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 5318Y has a base clock of 2.1 GHz and can boost up to 3.4 GHz depending on workload and thermal headroom. Intel manufactures the "Ice Lake-SP" silicon on a 10nm process node. This processor supports DDR4 memory across 8 channels, up to 6TB total, with ECC support standard for data integrity in server workloads. It supports both single-socket (1P) and dual-socket (2P) configurations, with 64 lanes of PCIe 4.0 available for storage, networking and accelerators. With a TDP of 165W, the Xeon Gold 5318Y runs hot and requires a capable cooling setup. The cache hierarchy consists of no dedicated of L1, no dedicated of L2, and 36MB of L3 cache.
Adds Intel Speed Select Technology (SST) support over the base Ice Lake-SP configuration, allowing post-deployment reconfiguration of core count and frequency priorities.
