Manufacturer Contact Info

The Intel Xeon 638 is a 16-core, 32-thread Granite Rapids server/workstation processor with 3.2 GHz base frequency, up to 4.8 GHz turbo, and 72MB L3 cache, suited to professional systems running demanding parallel workloads on a compatible single-socket LGA 4710 platform.

Recommended For

Workstation users running professional engineering, scientific, or media software that can use many CPU threads or Intel AVX-512/AMX instructions; the Xeon 638 combines 16 performance cores with 32 threads, though gains depend on software support.
Developers and technical teams compiling large projects or running several virtual machines on one workstation, where 16 cores, 32 threads, and Intel virtualization support suit parallel workloads.
Workstation builders handling memory-heavy projects who need ECC support and room to configure up to 2TB of DDR5 memory, provided four memory channels meet their bandwidth needs.
Professionals building a single-socket workstation with multiple PCIe devices, such as accelerators or high-speed storage, who can make use of the processor’s 80 PCIe 5.0 lanes.
