Intel Xeon 6776P socket: LGA 4710

What the Xeon 6776P is

The Intel Xeon 6776P is a 64-core high-frequency member of the Xeon 6 Granite Rapids stack on Socket LGA 4710. It runs 64 Performance-cores with Hyper-Threading for 128 threads at 2.3 GHz base with boost to 3.9 GHz and 3.6 GHz all-core turbo plus Priority Core Turbo to 4.6 GHz on up to 8 cores, backed by 336 MB of cache and a 350 W TDP. Intel launched the part in the second quarter of 2025 at a 11060 USD recommended price, built on Intel 3 for dual-socket performance racks.

Sixty-four fast cores suit databases, analytics clouds, HPC partitions and latency-sensitive platforms where per-thread speed matters alongside density. Priority Core Turbo lifts up to 8 favored cores to 4.6 GHz for licensed single-threaded work, while all-core bursts to 3.6 GHz hold parallel jobs at high frequency. The 336 MB cache pool keeps large working sets near the cores.

Against the 64-core Intel Xeon 6767P below it, the 6776P trades sustained clocks for higher peak turbo with Priority Cores. Against the 64-core Intel Xeon 6774P beside it, the two share the May 2025 wave with different frequency bins. Dual-socket support doubles the node where boards allow. 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 6776P 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 6776P fills a performance node or pairs with an identical 6776P in a dual-socket rack. 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 128 threads per socket supplied in database 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 performance 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 6776P has no larger dual-socket 64-core part above it in this batch besides the 86-core Intel Xeon 6787P on LGA 4710 boards where licenses allow. The 64-core Intel Xeon 6774P beside it shares the May 2025 wave at higher base clocks.

The step down to the 64-core Intel Xeon 6767P trims peak turbo for a lower price. A move to BGA 5026 is a different soldered platform with single-socket edge nodes. That change replaces board, memory and cooling from scratch.
