Intel · Xeon Gold · 2019 · LGA3647
The Intel Xeon Gold 6240Y is a server processor with 18 cores, released in 2019 at an MSRP of $2,726. It is part of the Xeon Gold lineup, using the Xeon Scalable platform, and fits the LGA3647 socket. Internally, it is built on the "Cascade Lake" architecture. Thanks to Intel Hyper-Threading, each core can handle two instruction streams simultaneously, yielding a total of 36 threads for improved parallelism. The Xeon Gold 6240Y has a base clock of 2.6 GHz and can boost up to 3.9 GHz depending on workload and thermal headroom. Intel manufactures the "Cascade Lake" silicon on a 14nm process node. This processor supports DDR4 memory across 6 channels, up to 1TB total, with ECC support standard for data integrity in server workloads. It supports both single-socket (1P) and dual-socket (2P) configurations, with 48 lanes of PCIe 3.0 available for storage, networking and accelerators. With a TDP of 150W, the Xeon Gold 6240Y runs hot and requires a capable cooling setup. The cache hierarchy consists of no dedicated of L1, no dedicated of L2, and 24.75MB of L3 cache.
Carries Intel's 'Y' suffix, enabling Intel Speed Select Technology (SST) — allowing the chip's core count and frequency profile to be dynamically reconfigured post-deployment for different workload priorities.
