Xeon X5667 Details

Ranked #1038 of 2060 in overall performance, the Intel Xeon X5667 presents a surprisingly competitive score for a processor launched in March 2010. With a single-core score of 4789 and a multicore score of 4764, it holds its own against modern CPUs in specific workloads, particularly when compared to lower-tier mobile and desktop processors. While its performance is no match for today’s top-tier chips—such as the Ryzen Threadripper PRO 9995WX or Core Ultra 9 285K—it remains a notable performer for its era and continues to serve niche applications in legacy server environments.

The Xeon X5667 is built on Intel’s Westmere-EP architecture, fabricated on a 32 nm process, and features four cores with eight threads enabled via Hyper-Threading. It operates at a base frequency of 3.06 GHz and can boost up to 3.46 GHz under load, supported by a 12 MB L3 cache and 0.061 MiB L1 and 0.244 MiB L2 caches. The processor uses a triple-channel DDR3 memory interface, supporting speeds up to 1333 MHz and a maximum of 288 GB of ECC-qualified RAM. It is designed for high-reliability server workloads, with integrated virtualization features including VT-x, VT-d, and EPT, making it suitable for virtualized environments.

Despite its age, the Xeon X5667 maintains relevance due to its robust feature set. It supports ECC memory, a critical capability for mission-critical systems, and includes advanced security and management features like Intel vPro, TXT, and SMEP. Its 95 W TDP and FCLGA1366 socket require careful cooling, but the processor remains stable under sustained loads. Although it lacks integrated graphics, it relies on external GPUs for display output, which is typical for server-class CPUs.

In terms of benchmark performance, the Xeon X5667 achieves a Passmark overall score of 4779, placing it ahead of many modern low-power processors like the Core i3-8130U and Core i5-3470T. Its single-core performance is particularly strong for its class, ranking above several current-generation Intel CPUs, including the Core i7-5600U and Core i7-965. However, its multicore performance lags behind modern quad- and hexa-core processors, especially when compared to the top 50 multicore performers.

As of March 2026, the Xeon X5667 is best suited for legacy server environments, small-scale virtualization, or embedded systems where its stability, ECC support, and multi-threading capabilities are valued. While it no longer competes with contemporary CPUs, its enduring design and feature set ensure it remains a reliable option in specific use cases where cost and compatibility with older infrastructure are priorities.
