Xeon W-3265M Details

With a 205 W TDP and 24 cores delivering 48 threads, the Intel Xeon W-3265M stands as a high-performance workstation processor rooted in the Cascade Lake SP architecture. Launched in the mid-2010s, it is now considered a legacy part, though its capabilities remain relevant in professional environments requiring substantial compute throughput. The processor operates at a base frequency of 2.7 GHz, with a turbo boost reaching 4.4 GHz, supported by a 14 nm manufacturing process and a 3647-pin LGA-3647 socket. It supports up to 2097152 MiB of DDR4-2933 memory across six channels, enabling a peak memory bandwidth of 131.13 GiB/s, which is essential for data-intensive applications like rendering, simulation, and scientific computing.

The Xeon W-3265M features a robust cache hierarchy, including 0.75 MiB of L1 instruction and data cache per core, 24 MiB of L2 cache, and a shared 33 MiB L3 cache, enhancing memory access efficiency. It also includes advanced instruction set support such as AVX-512, AES-NI, and Intel Deep Learning Boost, making it well-suited for machine learning, encryption, and high-performance computing workloads. The processor integrates features like Intel vPro, VT-x, VT-d, and Intel Secure Key Technology, providing strong virtualization, security, and management capabilities for enterprise environments.

In benchmark testing, the Xeon W-3265M achieves an Overall Score of 6091, placing it at #217 among 2060 processors, and a Multicore Score of 6965, ranking #104. Its Singlecore Score of 5509 places it at #544. While it trails behind modern high-end CPUs like the Ryzen Threadripper PRO 9995WX and Core Ultra 9 285K, it remains competitive with other Xeon W-series and high-core-count processors such as the Xeon Gold 6150 and Xeon W-3345. The multicore performance is particularly strong, outperforming many desktop and server chips with fewer cores, though its single-core performance is less competitive compared to current-generation consumer processors.

The Xeon W-3265M is best suited for professional workstations in engineering, video editing, 3D modeling, and data analytics, where sustained multi-threaded performance and ECC memory support are critical. As of March 2026, while newer processors have surpassed it in both raw performance and efficiency, the W-3265M continues to serve as a reliable option in legacy or specialized environments where its architecture and feature set are still valuable.
