Processor Intel Xeon Gold 6238R 2.2 GHz 16 Cores 38.5 MB LGA 3647

Processor Intel Xeon Gold 6238R operates at a base frequency of 2.2 GHz and is designed for server and workstation platforms. The CPU provides 16 physical cores with 38.5 MB of shared cache and supports advanced Intel technologies for virtualization, security and performance. Built on a 14 nm process and using the LGA 3647 socket, this Xeon supports up to 1.02 TB of DDR4 memory across six memory channels and includes instruction set extensions such as AVX-512 to accelerate compute‑intensive workloads.

Advantages

The Intel Xeon Gold 6238R integrates hardware features that enhance security, manageability and workload performance: virtualization technologies (VT-x, VT-d and EPT) enable efficient partitioning and I/O virtualization; Intel AES‑NI and Execute Disable Bit improve data protection and reduce exposure to malicious code; Intel Turbo Boost, Turbo Boost Max Technology 3.0 and Speed Shift deliver dynamic frequency scaling for better single‑thread and burst performance; AVX‑512 and DL Boost accelerate vector and AI inference tasks. Additional platform capabilities such as Intel vPro eligibility, Run Sure RAS features and support for Optane persistent memory increase platform reliability and scalability for mission‑critical server use.
