Intel Xeon 6511P socket: LGA 4710

What the Xeon 6511P is

The Intel Xeon 6511P is a 16-core single-socket member of the Xeon 6 Granite Rapids stack on Socket LGA 4710. It runs 16 Performance-cores with Hyper-Threading for 32 threads at 2.3 GHz base with boost to 4.2 GHz and 4.1 GHz all-core turbo, backed by 72 MB of cache and a 150 W TDP. Intel launched the 6700P and 6500P range on February 24, 2025 at a 978 USD recommended price, built on Intel 3 for single-socket racks.

Sixteen cores at 150 W suit branch servers, test beds, control planes and latency-sensitive services where a single fast socket matters more than socket count. The 2.3 GHz base keeps sustained work moving, while all-core bursts to 4.1 GHz hold parallel compiles at high frequency. The 72 MB cache pool keeps working sets near the cores.

Against the 16-core Intel Xeon 6515P below it, the 6511P matches clocks as a single-socket twin for simpler topologies. Against the 16-core Intel Xeon 6517P above it, the 6511P gives up base frequency for a lower price. 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 6511P fits LGA 4710 in the FCLGA4710 package with the E2B carrier, measuring 77.5 × 56.5 mm. Boards support a single socket with this 1S-only part, so one 6511P 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 32 threads supplied in branch and lab 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 frequency-node layout.

Cooling follows the board vendor list for the 150 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 6511P starts with the 16-core Intel Xeon 6517P for higher clocks on LGA 4710 boards where the budget allows. The 24-core Intel Xeon 6520P follows for more cores. Each move keeps memory investments where the board allows, plus a BIOS that already supports Granite Rapids.

The side move to the dual-capable Intel Xeon 6515P keeps similar clocks with a two-socket option for racks that outgrow one node. A move to BGA 4368 is a different soldered platform with single-socket edge nodes. That change replaces board, memory and cooling from scratch.
