Intel Xeon 6787P socket: LGA 4710

What the Xeon 6787P is

The Intel Xeon 6787P is the 86-core high-frequency member of the Xeon 6 Granite Rapids stack on Socket LGA 4710. It runs 86 Performance-cores with Hyper-Threading for 172 threads at 2.0 GHz base with boost to 3.8 GHz and 3.2 GHz all-core turbo, backed by 336 MB of cache and a 350 W TDP. Intel launched the 6700P and 6500P range on February 24, 2025 at a 11648 USD recommended price, built on Intel 3 for dual-socket performance clusters.

Eighty-six cores suit HPC partitions, large databases, analytics clouds and AI data pipelines where maximum threads and socket count both matter. The 2.0 GHz base keeps the 350 W envelope workable across two sockets, while bursts to 3.8 GHz clear single-threaded spikes. Four UPI links at 24 GT/s tie two sockets into one shared-memory node.

Against the 86-core Intel Xeon 6788P twin beside it, the 6787P shares clocks as a companion bin for dual-socket topologies without 8-socket validation. Against the 64-core Intel Xeon 6767P below it, the 6787P adds 22 cores for denser clusters. The E2A carrier marks the large-die package. See Socket vs chipset: what decides whether a CPU works for how socket, platform and firmware fit together on server boards.

Socket and motherboard compatibility

The 6787P fits LGA 4710 in the FCLGA4710 package with the E2A carrier, measuring 77.5 × 56.5 mm. Boards support one or two sockets with this dual-capable part, so one 6787P fills a dense node or pairs with an identical 6787P in a dual-socket cluster. LGA 4710 boards are platform designs with vendor-qualified power delivery, memory lists and firmware.

Granite Rapids shares the LGA 4710 socket with Sierra Forest E-core parts, so a board can host either family where the vendor lists it, after a BIOS update where needed. Dual-socket builds require identical part numbers in both sockets. Moving from any other socket is a full platform change with board, memory and heatsinks replaced together.

Memory, PCIe and cooling

Memory on LGA 4710 for this class is DDR5 up to 6400 MT/s in eight channels. Eight channels at these rates keep 172 threads per socket supplied in HPC and analytics mixes. Population order varies by board, so the vendor memory list governs every build, with matched DIMMs across sockets.

PCI Express connectivity is Gen 5 with up to 88 lanes on dual-socket designs. That lane budget feeds NVMe fabrics, 100-gigabit and faster networking and accelerators without lane sharing pressure. Lane bifurcation follows board firmware, so architects confirm slot maps before committing to a cluster layout.

Cooling follows the board vendor list for the 350 W class. No cooler ships with the tray server part. Firmware power limits can cap draw below the default where a cabinet demands it, at some cost in sustained clocks.

Upgrade paths

On the same socket, there is no larger dual-socket part above the 86-core 6787P in this batch besides the 8-socket Intel Xeon 6788P twin for larger topologies. The 64-core Intel Xeon 6767P below it keeps high clocks with fewer cores.

The step down to the 64-core Intel Xeon 6776P trims cores for peak-turbo bins. A move to LGA 7529 is a different larger platform with 12 memory channels for the biggest nodes. That change replaces board, memory and cooling from scratch.
