Xeon w7-3465X

The Xeon w7-3465X is a 28-core / 56-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 4.8 GHz from a base frequency of 2.5 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 75 MB of L3 cache, plus 2 MB (per core) of L2 cache and 80 kB (per core) of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 62,663, placing it in the Enthusiast performance tier as a Recent generation product. Geekbench 6 single-core (the most relevant metric for gaming FPS) records 1,959, while multi-core reaches 16,351.

The Xeon w7-3465X fits into the LGA4677 socket and supports PCIe 5.0 with 112 total PCIe lanes for expansion cards and storage. It supports DDR5-4800 memory at speeds up to DDR5-4800 (faster RAM improves bandwidth-sensitive workloads), with a maximum capacity of 4096 GB 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 features an unlocked multiplier, allowing enthusiasts to overclock beyond stock frequencies for additional performance. It supports AVX-512 instructions — specialized SIMD operations that significantly accelerate AI inference, scientific computing, and video encoding workloads. Virtualization: true — enables running virtual machines efficiently (important for development and server workloads). Its primary market competitor is the Threadripper PRO 7965WX.

The Xeon w7-3465X has a rated TDP (Thermal Design Power) of 300 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: High-end Liquid.

At an average price of $468 (MSRP: $2889), the Xeon w7-3465X delivers 134 PassMark points per dollar. Performance ranking position: #114 out of all indexed processors.
