INTEL Xeon 6238R 2.20GHz CPU
The Intel Xeon Gold 6238R is a 28-core, 56-thread Cascade Lake processor built for dual-socket servers and workstations, suited to virtualization hosts, compute-heavy workloads, and storage or database platforms that benefit from high core counts and AVX-512 support. It targets integrators and resellers refreshing LGA 3647 platforms or building capacity-dense nodes on a proven architecture. Note that features such as memory speed and multi-socket operation depend on motherboard and platform support, so verify system compatibility before ordering.

Good to know
- Compatibility: requires an LGA 3647 motherboard with Cascade Lake platform support; confirm BIOS revision and VRM/cooling headroom for the 165 W TDP, especially in dual-socket configurations.
- Family positioning: the “R” suffix denotes a higher-core-count refresh within the Xeon Gold Cascade Lake line, offering more cores than the original Gold 6238 at the same 2.2 GHz base clock, making it a common drop-in densification option for existing LGA 3647 deployments.
- Buying tip: when sourcing for capacity planning, size memory across all 6 channels per CPU to realize DDR4-2933 speeds, and confirm your workload can exploit AVX-512 (e.g., HPC, inference, simulation) to take full advantage of DL Boost support.
