Xeon X5670 Details

The Intel Xeon X5670, launched in March 2010, represents a significant step in server and workstation computing during the early 2010s, built on Intel's Westmere-EP architecture at a 32 nm process node. While now nearly 14 years old, it was once a cornerstone in multi-threaded workloads, offering six cores and a base clock of 2.93 GHz, with a turbo boost up to 3.33 GHz. The processor's design emphasizes scalability, supporting up to two CPUs in a symmetric multiprocessing (SMP) configuration, making it ideal for high-throughput server environments. It operates on Socket 1366 and features a 95 W TDP, which, while moderate by today's standards, required effective cooling solutions due to its power draw. The Xeon X5670 lacks integrated graphics, necessitating a discrete GPU for display output, and includes ECC memory support, a critical feature for mission-critical systems where data integrity is paramount.

In terms of performance, the Xeon X5670 achieves an overall Passmark score of 4600, placing it at rank #1191 out of 2060 processors. Its single-core performance scores 4543, ranking #1255, and its multicore score reaches 4685, placing it #986. These results highlight a processor balanced for multi-threaded tasks, though its single-core performance is less competitive by modern standards. The multicore score is particularly strong when compared to some of its contemporaries, such as the Xeon X3460 and Xeon E3-1270 v3, and it narrowly edges out the Xeon W3570 and Core i5-3470 in multicore performance. However, it trails behind newer Intel and AMD processors like the Core i5-4440 and Core i7-2760QM, which achieve slightly higher scores despite having lower core counts.

The Xeon X5670 supports a wide range of instruction sets, including AVX, AES-NI, and Hyper-Threading, which doubles the effective thread count to 12. This enables efficient handling of virtualization workloads, thanks to technologies like VT-x and EPT, and makes it suitable for running multiple virtual machines simultaneously. Its cache hierarchy includes 61 MiB of L1, 244 MiB of L2, and a substantial 11.44 MiB of L3 cache, which aids in reducing memory latency for data-intensive operations. The triple-channel DDR3 memory interface further enhances bandwidth, though it is now outdated compared to modern memory standards.

Despite its age, the Xeon X5670 remains a reliable option for legacy systems and specific server applications where its ECC support and SMP scalability are essential. As of March 2026, while it is far from the top-tier performance seen in today’s processors like the Ryzen Threadripper PRO 9995WX or Core Ultra 9 285K, it still holds value in environments prioritizing stability and backward compatibility. Its strengths lie in multi-threaded server workloads, virtualization, and systems requiring ECC memory, though it is outpaced by modern CPUs in single-core performance and power efficiency.
