Intel Xeon 6781P 80-core desktop processor

The Intel Xeon 6781P is an 80-core desktop processor built on the Granite Rapids architecture for LGA 4710 platforms. It delivers 160 threads with a 2.0 GHz base frequency and a 3.8 GHz max turbo frequency, supported by 336 MB of L3 cache. This CPU targets high-throughput workloads such as virtualisation, database serving and compute-intensive analytics on single-socket systems.

Upgrade from lower-core Xeon or workstation CPUs

Moving to this 80-core part makes sense when thread count and memory bandwidth become the primary bottlenecks. The jump is worth it for workloads that scale across 160 threads and can exploit eight channels of DDR5 at 6400 MT/s or MRDIMM at 8800 MT/s. Systems limited by PCIe lane count also benefit from the 136 lanes of PCIe 5.0 connectivity.

4 TB memory capacity with eight-channel bandwidth

The integrated memory controller supports up to 4 TB of ECC DDR5 or MRDIMM across eight channels, providing ample headroom for large in-memory databases and virtualised environments. Bandwidth scales with MRDIMM at 8800 MT/s for memory-bound kernels. The 350 W TDP and lack of included cooling mean thermal infrastructure must handle sustained 3.2 GHz all-core turbo operation.

Questions about this item

What LGA 4710 socket and 350 W TDP cooler clearance does the Xeon 6781P require?

The processor fits an LGA 4710 socket and has a 350 W thermal design power, so the cooler must be rated for at least that heat load and clear the socket's mechanical keep-out zone.

How is the Xeon 6781P installed in the LGA 4710 socket, and which step is most often missed?

Align the gold triangle on the processor with the socket marker, lower it gently without forcing, close the load plate, then torque the four captive screws in a cross pattern to the board-maker's specified value — skipping the cross-pattern torque is the common error.

When will the thermal interface material on the Xeon 6781P need replacement?

Replace the paste whenever the cooler is removed or if temperatures rise above normal after several years of continuous 350 W operation.
