Manufacturer Contact Info

The Intel Xeon 676X is a 32-core, 64-thread Granite Rapids server processor for single-socket systems that need high parallel compute capacity, with boost speeds up to 4.9 GHz and 144MB of L3 cache.

Recommended For

Workstation users running CPU-parallel rendering, simulation, engineering, or scientific jobs can use its 32 cores and 64 threads for workloads that keep many cores busy.
Professionals building a workstation around several GPUs, high-speed storage, or other PCIe devices can use the platform’s 128 PCIe 5.0 lanes to support high-connectivity configurations.
Scientific, analytics, or engineering teams working with large in-memory datasets can build around eight memory channels, ECC support, and capacity of up to 4 TB, subject to compatible memory and motherboard support.
Developers and technical teams running CPU-based machine-learning or other AVX-512/AMX-enabled workloads can consider it when their software benefits from those instruction sets and sustained workstation-class CPU resources.
