Xeon w7-3445 Details

The Intel Xeon w7-3445 stands out as a high-end workstation processor designed for demanding professional workloads, particularly in content creation, 3D rendering, and scientific computing. Launched in February 2023, this CPU is built on Intel's Sapphire Rapids architecture, a 10 nm process node that delivers strong multi-threaded performance while maintaining robust feature support. With 20 cores and 40 threads enabled via Hyper-Threading, the Xeon w7-3445 offers substantial parallel processing power, making it competitive in the high-end workstation segment. Its 2.5 GHz base frequency and up to 4.8 GHz turbo boost provide strong single-threaded responsiveness, though it's the core count and memory bandwidth that define its strength.

The processor is built on a 477 mm² die, fabricated using Intel's 10 nm process, and features a large 52.5 MB L3 cache that significantly reduces memory latency for data-intensive applications. It operates at a 270 W TDP, indicating a high-power design that demands efficient cooling solutions, and is packaged in the FC-LGA16A socket with Socket 4677. The Xeon w7-3445 supports eight-channel DDR5 memory, with a maximum rated speed of 4800 MT/s and ECC support, ensuring data integrity in mission-critical environments. It also supports PCIe 5.0 with 112 lanes directly from the CPU, enabling high-speed connectivity for modern storage and expansion cards.

In benchmark testing, the Xeon w7-3445 achieves an overall score of 6730, ranking #90 among 2060 processors, with a multicore score of 7211 (#82) and a single-core score of 6409 (#133). These results place it just behind higher-end Xeon models like the w7-3455 and w7-3465X, but ahead of most mainstream consumer CPUs. Its multicore performance is particularly strong, outperforming many desktop processors despite its higher TDP and server-oriented design. However, its single-core performance, while respectable, trails behind top-tier consumer chips like the Core Ultra 9 285K and Ryzen 9 9950X3D.

The Xeon w7-3445 lacks integrated graphics, requiring a discrete GPU for visual output, which is typical for workstation-class processors. It supports a wide range of advanced instruction sets, including AVX-512, AVX2, SSE, and Intel's virtualization technologies like VT-x and VT-d, making it ideal for virtualized environments and data-heavy applications. With no locked multiplier, it offers some overclocking headroom, though this is limited by its high power consumption.

As of March 2026, the Xeon w7-3445 remains a viable option for professionals requiring high core counts and ECC memory in a workstation setup. While newer processors have since entered the market, its balance of core density, memory bandwidth, and enterprise-grade features ensures it remains relevant for tasks such as video editing, CAD, and simulation workloads. Its main limitation lies in its power consumption and cooling requirements, which make it less suitable for standard desktop use.
