Intel Xeon 6731P socket: LGA 4710

What the Xeon 6731P is

The Intel Xeon 6731P is a 32-core single-socket member of the Xeon 6 Granite Rapids stack on Socket LGA 4710. It runs 32 Performance-cores with Hyper-Threading for 64 threads at 2.5 GHz base with boost to 4.1 GHz and 3.9 GHz all-core turbo, backed by 144 MB of cache and a 245 W TDP. Intel launched the 6700P and 6500P range on February 24, 2025, built on Intel 3 for single-socket racks.

Thirty-two cores suit virtualization hosts, storage controllers, branch consolidation boxes and test labs where balanced threads matter more than peak clocks. The 2.5 GHz base keeps sustained work moving, while all-core bursts to 3.9 GHz cover parallel compiles. The 144 MB cache pool keeps working sets near the cores across 8 DDR5 channels.

Against the 32-core Intel Xeon 6530P below it, the 6731P trades dual-socket scaling for single-socket simplicity at similar clocks. Against the 32-core Intel Xeon 6730P above it in cache, the 6731P trades cache depth for a lower 245 W class. Single-socket validation trims firmware paths. 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 6731P fits LGA 4710 in the FCLGA4710 package, measuring 77.5 × 56.5 mm. Boards support a single socket with this 1S-only part, so one 6731P fills the 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 64 threads supplied in virtualization and storage mixes. Population order varies 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 arrays and high-speed networking without lane sharing pressure. Lane bifurcation follows board firmware, so architects confirm slot maps before committing to a balanced-node layout.

Cooling follows the board vendor list for the 245 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 6731P starts with the 32-core Intel Xeon 6730P for more cache on LGA 4710 boards where the budget allows. The 32-core Intel Xeon 6745P follows for higher clocks. Each move keeps memory investments where the board allows, plus a BIOS that already supports Granite Rapids.

The step down to the 32-core Intel Xeon 6530P adds dual-socket scaling at similar clocks. A move to BGA 4368 is a different soldered platform with single-socket edge nodes. That change replaces board, memory and cooling from scratch.
