Intel Xeon 6728P socket: LGA 4710

What the Xeon 6728P is

The Intel Xeon 6728P is a 24-core member of the Xeon 6 Granite Rapids stack on Socket LGA 4710. It runs 24 Performance-cores with Hyper-Threading for 48 threads at 2.7 GHz base with boost to 4.1 GHz and 3.9 GHz all-core turbo, backed by 144 MB of cache and a 210 W TDP. Intel launched the 6700P and 6500P range on February 24, 2025, built on Intel 3 for clusters up to 8 sockets.

Twenty-four cores suit virtualization estates, scale-out databases, analytics partitions and shared-memory HPC jobs where balanced threads and scaling both matter. The 2.7 GHz base keeps sustained work moving, while all-core bursts to 3.9 GHz hold parallel jobs at high frequency. Eight-socket scaling spreads large working sets across many nodes.

Against the 24-core Intel Xeon 6520P below it, the 6728P adds base frequency and 8-socket scaling at the same 210 W class. Against the 24-core Intel Xeon 6527P above it, the two share clocks with different scaling stories. 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 6728P fits LGA 4710 in the FCLGA4710 package, measuring 77.5 × 56.5 mm. Boards support up to 8 sockets with this scalable part, so one 6728P fills a balanced node or groups with identical 6728P parts in large clusters. 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. Multi-socket builds require identical part numbers in every socket. 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 48 threads per socket supplied in virtualization 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 multi-socket designs. That lane budget feeds NVMe fabrics and high-speed networking without lane sharing pressure. Lane bifurcation follows board firmware, so architects confirm slot maps before committing to a cluster layout.

Cooling follows the board vendor list for the 210 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 6728P starts with the 24-core Intel Xeon 6527P for higher clocks on LGA 4710 boards with dual-socket topologies. The 32-core Intel Xeon 6530P follows for more cores. Each move keeps memory investments where the board allows, plus a BIOS that already supports Granite Rapids.

The step down to the 24-core Intel Xeon 6520P trims clocks for the same 210 W class on simpler boards. A move to BGA 4368 is a different soldered platform with single-socket edge nodes. That change replaces board, memory and cooling from scratch.
