Xeon w7-3545

The Xeon w7-3545 is a 24-core / 48-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 2.7 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 67.5 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 58,453, placing it in the Enthusiast performance tier as a Recent generation product. Geekbench 6 single-core (the most relevant metric for gaming FPS) records 2,300, while multi-core reaches 16,200.

The Xeon w7-3545 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 w7-3545 has a rated TDP (Thermal Design Power) of 310 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 $2,039, the Xeon w7-3545 delivers 29 PassMark points per dollar. Performance ranking position: #142 out of all indexed processors.
