Xeon 6781P

The Xeon 6781P is a 80-core / 160-thread processor based on the Granite Rapids (2024−2025) architecture, manufactured on a Intel 3 nm process node. It reaches a maximum boost clock of 3.8 GHz from a base frequency of 2 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. With a massive 336 MB (total) L3 cache (3D V-Cache technology), this processor has a significant gaming advantage — the large cache drastically reduces memory latency in game engines., plus 2 MB (per core) of L2 cache and 112 kB (per core) of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 117,946, placing it in the Enthusiast performance tier as a Current Gen generation product.

The Xeon 6781P fits into the LGA4710 socket and supports PCIe 4.0 with 136 total PCIe lanes for expansion cards and storage. It supports DDR5(6400MT/s), MRDIMM(8800MT/s) memory at speeds up to DDR5-6400 (faster RAM improves bandwidth-sensitive workloads), with a maximum capacity of 4 TB across 8 channels (dual-channel doubles bandwidth). It supports ECC memory, providing error-correcting capabilities — essential for mission-critical workloads and servers.

The Xeon 6781P is primarily designed for Data Center / Cloud Scale. Virtualization: VT-x, VT-d, VT-x EPT — enables running virtual machines efficiently (important for development and server workloads). Its primary market competitor is the EPYC 9655.

The Xeon 6781P has a rated TDP (Thermal Design Power) of 350 Watt — this indicates the amount of heat generated under sustained load and determines what cooling solution is needed. No stock cooler is included — you will need to purchase an aftermarket cooler separately. Recommended cooling: Server Grade Air/Liquid.

At an average price of $8,960, the Xeon 6781P delivers 13 PassMark points per dollar. Performance ranking position: #21 out of all indexed processors.
