Xeon Platinum 8470

The Xeon Platinum 8470 is a 52-core / 104-thread processor based on the Sapphire Rapids (2023−2024) architecture, manufactured on a Intel 7 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 105 MB 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 80K (per core) of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 89,850, placing it in the Enthusiast performance tier as a Recent generation product.

The Xeon Platinum 8470 fits into the LGA4677 socket and supports PCIe 5.0 with 80 total PCIe lanes for expansion cards and storage. It supports DDR5-4800, DDR5-4400 memory at speeds up to DDR5-4800 (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 Platinum 8470 is primarily designed for Cloud Infrastructure. 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 9534.

The Xeon Platinum 8470 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 $9,359, the Xeon Platinum 8470 delivers 10 PassMark points per dollar. Performance ranking position: #48 out of all indexed processors.
