Intel Xeon 6781P socket: LGA 4710

What the Xeon 6781P is

The Intel Xeon 6781P is the 80-core density member of the Xeon 6 Granite Rapids stack on Socket LGA 4710. It runs 80 Performance-cores with Hyper-Threading for 160 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 10035 USD recommended price, built on Intel 3 for single-socket dense nodes, with Speed Select server, network and compute modes.

Eighty cores in one socket suit cloud hosts, content delivery, analytics and storage clusters that scale by thread count rather than socket count. The 2.0 GHz base keeps the 350 W envelope workable for high-airflow racks, while 160 threads absorb massive parallel jobs. The 336 MB cache pool keeps data near the cores across 8 DDR5 channels.

Against the 64-core Intel Xeon 6761P below it, the 6781P adds 16 cores for sites that bill by density per unit. Against the 86-core Intel Xeon 6788P above it, the 6781P trades multi-socket scaling for single-socket simplicity. Speed Select modes tune the same silicon for server, network or compute profiles. 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 6781P fits LGA 4710 in the FCLGA4710 package with the E2A carrier, measuring 77.5 × 56.5 mm. Boards support a single socket with this 1S-only part, so one 6781P fills the densest node and there is no second-socket upgrade to plan. 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. 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 160 threads supplied in cloud, analytics and storage mixes. Population order and maximum capacity vary by board, so the vendor memory list governs every build.

PCI Express connectivity is Gen 5 with up to 136 lanes on single-socket designs. That lane budget feeds NVMe fleets, high-speed networking and accelerators on the densest node without lane sharing pressure. Lane bifurcation follows board firmware, so architects confirm slot maps before committing to a maximum-density 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, the path up from the 6781P is the 86-core Intel Xeon 6788P for more threads on LGA 4710 boards with multi-socket topologies. The move adds scaling options beside core count.

The step down to the 64-core Intel Xeon 6761P trims cores for a lower price. 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.
