86-Core Xeon 6787P for Scale-Out Servers

The Intel Xeon 6787P is an 86-core server processor built on the Granite Rapids architecture for dense compute clusters. It runs at a 2.0 GHz base frequency and reaches 3.8 GHz max turbo across its 172 threads. The FCLGA 4710 socket supports dual-socket configurations with four UPI links at 24 GT/s.

Suited for High-Throughput Workloads.

This CPU fits workloads that scale across many threads such as virtualisation farms, database clusters and HPC simulations. The 350 W thermal design power and omitted cooler require robust server infrastructure. Buyers needing a quiet single-socket workstation or a passively cooled edge node should look elsewhere.

336 MB L3 Cache Decides Fit for Memory-Bound Tasks

The shared 336 MB L3 cache is the single specification that determines whether this part matches your dataset size. Eight DDR5 channels at 6400 MT/s and MRDIMM support at 8000 MT/s feed the cores, while 88 PCIe 5.0 lanes handle accelerators and fast storage.

Questions about this item

What motherboard socket is required for the FCLGA 4710 package on this Xeon 6787P?

The processor fits an FCLGA 4710 socket, so the motherboard must provide that exact socket type.

Will the 8-channel DDR5 controller running at 6400 MT/s work with slower DDR5 DIMMs already installed in a 2S platform?

Yes, the integrated memory controller supports DDR5 at 6400 MT/s and will down-clock to match slower modules while keeping all 8 channels active.

How can I confirm the 86 cores and 172 threads are recognised after installation?

Check the operating system CPU topology or BIOS POST screen; both should report 86 physical cores and 172 logical threads for the Xeon 6787P.
