Intel · Xeon Gold · 2019 · LGA3647
The Intel Xeon Gold 6238 is a server processor with 22 cores, released in 2019 at an MSRP of $2,612. 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 44 threads for improved parallelism. The Xeon Gold 6238 has a base clock of 2.1 GHz and can boost up to 3.7 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 140W, the Xeon Gold 6238 sits in a typical power envelope for a modern desktop CPU. The cache hierarchy consists of no dedicated of L1, no dedicated of L2, and 30.25MB of L3 cache.
Standard-configuration Cascade Lake part at this core count, distinct from the memory-capacity-enhanced 6238L.
