64-core Xeon 6 for single-socket servers

The Intel Xeon 6 6761P is a 64-core, 128-thread server processor built for single-socket platforms. It targets compute-dense workloads such as virtualization, database analytics and high-performance computing where core count and memory bandwidth matter more than multi-socket scaling.

FCLGA 4710 socket and 1S-only scalability

This CPU fits the FCLGA 4710 socket and is validated for 1S-only configurations. The socket choice and single-socket limitation are the decisive compatibility factors; systems designed for dual-socket operation or a different socket generation cannot use this processor.

336 MB L3 cache, 4 TB DDR5 across eight channels

The 336 MB L3 cache and eight-channel memory controller supporting DDR5 at 6400 MT/s and MRDIMM at 8000 MT/s provide ample bandwidth for large working sets. Memory capacity tops out at 4 TB, while 136 PCIe 5.0 lanes handle high-throughput I/O; beyond that ceiling, additional memory or expansion requires a different platform.

Questions about this item

How does the 3.6 GHz all-core turbo behave inside a real server?

When all 64 cores are active the processor sustains 3.6 GHz within its 350 W thermal envelope, so heavily threaded workloads run at that frequency rather than dropping to the 2.5 GHz base.

What does the PCI Express 5.0 interface with 136 lanes cap in practice?

The 136 lanes of PCIe 5.0 provide enough bandwidth for multiple high-speed accelerators, storage controllers and network adapters without forcing lane-sharing compromises.

What does the FCLGA 4710 socket require for mounting and cooling?

The FCLGA 4710 land-grid socket needs a compatible server board and a cooler rated for 350 W TDP; no cooling device is included with the processor-only package.
