Intel · Xeon Gold · 2019 · LGA3647
The Intel Xeon Gold 6238L is a server processor with 22 cores, released in 2019. 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 6238L 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 6238L 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.
Shares the 6238's core count and clocks but adds Intel's 'L'-suffix higher maximum memory capacity support.
