Xeon w5-2545

The Xeon w5-2545 is a 12-core / 24-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 4.7 GHz from a base frequency of 3.5 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 30 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 40,782, placing it in the Enthusiast performance tier as a Recent generation product.

The Xeon w5-2545 fits into the LGA4677 socket and supports PCIe 4.0 with 64 total PCIe lanes for expansion cards and storage. It supports DDR5-4800 memory at speeds up to 4800 (faster RAM improves bandwidth-sensitive workloads), with a maximum capacity of 2048 across 4 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: VT-x, VT-d — enables running virtual machines efficiently (important for development and server workloads). Its primary market competitor is the Threadripper 7960X.

The Xeon w5-2545 has a rated TDP (Thermal Design Power) of 210 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: LGA4677 Workstation Cooler.

At an average price of $1,100 (MSRP: $889), the Xeon w5-2545 delivers 37 PassMark points per dollar. Performance ranking position: #281 out of all indexed processors.
