Intel Xeon 638 Granite Rapids 3.2 GHz 72MB L3 Cache LGA 4710 180W Server Processor - OEM

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.

Real-World Use Scenarios

• When compiling a large software project while keeping development tools, tests, and other work running, the 16-core Xeon 638 can handle multiple CPU tasks concurrently; build times still depend on the software and how well it uses parallel processing.
• For a workstation used for 3D rendering, media processing, or other CPU-based production tasks, its 16 cores can work on parallelizable jobs while the user continues other work; expect results to vary with the application, project, and graphics card.
• When developing or testing CPU-based AI and machine-learning software, compatible applications can use Intel AMX to accelerate supported operations; actual gains depend on software support, and this 16-core model is better suited to modest workstation workloads than assuming large-model training will run quickly on the CPU alone.
• For engineering or creative work that needs several expansion cards—such as a graphics card plus high-speed storage or networking—the Xeon 638 can support a workstation built around multiple PCIe devices; the number and bandwidth of usable slots depend on the motherboard and its layout.
• When running virtual machines for software testing, isolated development environments, or small lab services, the Xeon 638 can host several CPU-sharing workloads; practical VM count and responsiveness depend heavily on memory, storage, and each VM’s workload.
