Intel Xeon 6788P socket: LGA 4710

What the Xeon 6788P is

The Intel Xeon 6788P is the 86-core flagship 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 21280 USD recommended price, built on Intel 3 for clusters up to 8 sockets.

Eighty-six cores suit HPC clusters, large databases, analytics clouds and AI data pipelines where thread count and memory bandwidth decide throughput. The 2.0 GHz base keeps the 350 W envelope workable across many sockets, while bursts to 3.8 GHz clear single-threaded spikes. Four UPI links at 24 GT/s tie up to 8 sockets into one shared-memory node.

Against the 80-core Intel Xeon 6781P below it, the 6788P adds 6 cores and multi-socket scaling for cluster growth. Against the 64-core Intel Xeon 6761P below it, the 6788P adds 22 cores with full 8-socket topologies. 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 6788P fits LGA 4710 in the FCLGA4710 package with the E2A carrier, measuring 77.5 × 56.5 mm. Boards support up to 8 sockets with this scalable part, so one 6788P fills a single node or groups with identical 6788P parts in large clusters. 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. Multi-socket builds require identical part numbers in every socket. 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 supplied in HPC, database and analytics mixes. Population order and maximum capacity vary 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 multi-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 with an 80 degree case limit. 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 Granite Rapids part above the 86-core 6788P in this batch, so growth on LGA 4710 means adding sockets up to 8 rather than a bigger chip. The 80-core Intel Xeon 6781P beside it keeps high density on single-socket boards.

The step down to the 64-core Intel Xeon 6761P trims cores for single-socket nodes. A move to BGA 5026 is a different soldered platform with 64 single-socket cores for edge nodes. That change replaces board, memory and cooling from scratch.
