Intel Xeon 6505P socket: LGA 4710

What the Xeon 6505P is

The Intel Xeon 6505P is the 12-core entry member of the Xeon 6 Granite Rapids stack on Socket LGA 4710. It runs 12 Performance-cores with Hyper-Threading for 24 threads at 2.2 GHz base with boost to 4.1 GHz and 3.9 GHz all-core turbo, backed by 48 MB of cache and a 150 W TDP. Intel launched the 6700P and 6500P range on February 24, 2025 at a 676 USD recommended price, built on Intel 3 for dual-socket racks.

Twelve cores at 150 W suit branch servers, test beds, control planes and light virtualization hosts where a low price matters more than peak density. The 2.2 GHz base keeps sustained work moving, while all-core bursts to 3.9 GHz cover parallel compiles. One product brief table lists 72 MB against the ARK page value of 48 MB, and this page follows the ARK manufacturer value.

Against the 16-core Intel Xeon 6515P above it, the 6505P trims cores for the lowest Granite Rapids socketed price in this batch. Against the 8-core Intel Xeon 6507P below it, the 6505P adds 4 cores for denser tenants. 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 6505P fits LGA 4710 in the FCLGA4710 package, measuring 77.5 × 56.5 mm. Boards support one or two sockets with this dual-capable part, so one 6505P fills an entry node or pairs with an identical 6505P 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 24 threads per socket well supplied in branch and lab 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 arrays and high-speed networking without lane sharing pressure. Lane bifurcation follows board firmware, so architects confirm slot maps before committing to an entry-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 6505P starts with the 16-core Intel Xeon 6515P for more threads on LGA 4710 boards where the budget allows. The 16-core Intel Xeon 6517P 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 8-core Intel Xeon 6507P halves the cores for frequency-first licenses. A move to BGA 4368 is a different soldered platform with single-socket edge nodes. That change replaces board, memory and cooling from scratch.
