Manufacturer Contact Info

The Intel Xeon 658X is a 24-core, 48-thread workstation processor for professional systems running heavily threaded workloads, with a 3.0 GHz base clock, boost speeds up to 4.9 GHz, and 144 MB of L3 cache.

Recommended For

Workstation builders who need substantial memory capacity and room for several high-speed expansion cards—such as GPUs, storage, or networking—without moving to a higher-core Xeon: the 658X supports up to 4TB of memory and 128 PCIe 5.0 lanes.
Professionals running local CPU-based AI inference or workloads that can use Intel AMX, who want a workstation-class CPU rather than relying on a GPU for every inference task; StorageReview reported strong CPU-inference results for the 658X.
Engineering, design, and development teams building a single-socket workstation for mixed workloads—interactive work alongside threaded tasks—that benefit from ECC memory, eight memory channels, and broad PCIe expansion.
Workstation buyers seeking the newer Xeon 600 platform’s memory and I/O capabilities without paying for a 48-, 64-, or 86-core model, and whose work does not depend on maximum CPU-rendering throughput.
