Xeon X5687 Details

The Intel Xeon X5687, launched in February 2011, stands as a relic of the early 2010s server and workstation landscape, now more than 15 years old. Despite its age, it remains a notable example of Intel's Westmere-EP architecture, built on a 32 nm process and designed for high-performance multi-threaded workloads in enterprise environments. With a base clock of 3.6 GHz and a turbo boost up to 3.866 GHz, the processor leverages Intel Hyper-Threading to deliver eight logical threads across four physical cores. Its 130 W TDP reflects the power demands of that era, requiring robust cooling solutions, and it operates on the Socket 1366 platform, which was common for high-end desktop and server systems at the time.

The Xeon X5687 features a substantial 11.444 MiB L3 cache, a significant advantage for data-intensive tasks, and supports triple-channel DDR3 memory, allowing for high memory bandwidth critical in server applications. ECC memory support ensures data integrity, making it suitable for mission-critical systems. While lacking integrated graphics, the processor relies on external GPUs for visual output. It supports advanced instruction sets including AVX, AVX2, AES-NI, and SSE4.2, enhancing performance in encryption, multimedia, and scientific computing. Virtualization features like VT-x and TXT further strengthen its enterprise credentials.

In benchmark testing, the Xeon X5687 achieves an Overall Score of 4607, ranking #1186 out of 2060 processors, with a Singlecore Score of 4732 (#1131) and a Multicore Score of 4420 (#1408). These results place it behind many modern processors but ahead of several mid-range and low-power chips from the same generation. For example, it outperforms the Core i5-6200U and Athlon II X2 265, yet trails behind the Core i7-4650U and Intel Core i3-7100U in single-threaded tasks. In multi-threaded performance, it surpasses the Xeon X3470 and Core i7 860 but falls short of the Xeon D-1527 and Core i7-4510U.

When compared to today’s top-tier processors, the Xeon X5687 is far from competitive. The highest-performing CPUs, such as the Ryzen Threadripper PRO 9995WX and Core Ultra 9 285K, achieve scores over 9000, dwarfing the X5687's capabilities. Even within its own era, it was outpaced by newer Xeon models like the Xeon E5-2690 and Xeon X5670. However, for legacy systems or specific use cases where backward compatibility is required, it still offers a reliable platform. Its strong multithreaded performance, combined with ECC memory and virtualization support, makes it a viable option for older server workloads, though it is no longer suitable for modern, high-demand applications.

As of March 2026, the Xeon X5687 serves primarily as a historical benchmark and a testament to Intel’s early 32 nm server processor design. While it lacks the efficiency and performance of contemporary CPUs, its architectural features—such as simultaneous multithreading, AVX support, and ECC memory—were groundbreaking at the time. For users maintaining legacy infrastructure, it remains a functional, albeit outdated, option. Newer systems demand processors with higher clock speeds, advanced instruction sets, and lower power consumption, leaving the X5687 firmly in the past.
