Xeon W-3265M

The Xeon W-3265M is a 24-core / 48-thread processor based on the Cascade Lake (2019−2020) architecture, manufactured on a 14 nm process node. It reaches a maximum boost clock of 4.6 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 33 MB of L3 cache, plus 24 MB of L2 cache and 1.5 MB of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 35,506, placing it in the High-End performance tier as a Legacy generation product.

The Xeon W-3265M fits into the LGA3647 socket and supports PCIe 5.0 with 64 total PCIe lanes for expansion cards and storage. It supports DDR4-2933 memory at speeds up to 2933 (faster RAM improves bandwidth-sensitive workloads), with a maximum capacity of 1024 across 6 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 7402.

The Xeon W-3265M has a rated TDP (Thermal Design Power) of 205 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: LGA3647 Workstation Cooler.

At an average price of $3,500 (MSRP: $6300), the Xeon W-3265M delivers 10 PassMark points per dollar. Performance ranking position: #338 out of all indexed processors.
