Xeon 6505P

The Xeon 6505P is a 12-core / 24-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 4.1 GHz from a base frequency of 2.2 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 48 MB (total) of L3 cache, 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 39,341, placing it in the High-End performance tier as a Current Gen generation product.

The Xeon 6505P fits into the LGA4710 socket and supports PCIe 5.0 with 88 total PCIe lanes for expansion cards and storage. It supports DDR5(6400MT/s) memory at speeds up to 6400 (faster RAM improves bandwidth-sensitive workloads), with a maximum capacity of 4096 across 8 channels (dual-channel doubles bandwidth). It supports ECC memory, providing error-correcting capabilities — essential for mission-critical workloads and servers. Integrated graphics: None — allows display output without a dedicated GPU, useful for troubleshooting and light tasks.

It supports AVX-512 instructions — specialized SIMD operations that significantly accelerate AI inference, scientific computing, and video encoding workloads. Virtualization: VT-x, VT-d — enables running virtual machines efficiently (important for development and server workloads). Its primary market competitor is the EPYC 9334.

The Xeon 6505P has a rated TDP (Thermal Design Power) of 150 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: Granite Rapids Server Grade.

At an average price of $563, the Xeon 6505P delivers 70 PassMark points per dollar. Performance ranking position: #298 out of all indexed processors.
