Xeon E5620 Details

As of March 2026, the Intel Xeon E5620 remains a relic of the early 2010s server and workstation landscape, having been launched in March 2010. While it is no longer relevant in modern computing, its performance in historical benchmarks still offers insight into the evolution of multi-core processors. With a base clock of 2.4 GHz and a turbo frequency of 2.66 GHz, the Xeon E5620 is built on Intel's Westmere-EP microarchitecture, fabricated on a 32 nm process and featuring 1.17 billion transistors. It is designed for server environments and supports dual-processor configurations, making it suitable for mid-tier workstations and entry-level servers of its era.

The processor features four cores with simultaneous multithreading, effectively delivering eight threads, and includes a substantial 11.444 MiB L3 cache, which was significant at the time. It supports up to 288 GB of DDR3 memory across a triple-channel memory interface, with a maximum bandwidth of 25.6 GB/s. The Xeon E5620 operates at a TDP of 80 W and requires a Socket FCLGA1366, which was common for Intel’s high-end desktop and server platforms during its era.

In terms of performance, the Xeon E5620 achieves an overall score of 4377, ranking #1436 out of 2060 processors in the benchmark database. Its single-core score is 4304, placing it at #1484, while its multicore score stands at 4487, ranking #1251. These scores indicate that the processor is outperformed by nearly all modern CPUs, particularly in single-threaded tasks, where it ranks behind many low-power and mobile processors. However, its multicore performance remains competitive against older dual-core and early quad-core designs.

The Xeon E5620 supports a wide range of Intel technologies, including Hyper-Threading, AES-NI, AVX2, and virtualization features such as VT-x and VT-d. It also includes ECC memory support, making it suitable for mission-critical systems where data integrity is essential. Despite its age, the processor still holds value in legacy systems and for enthusiasts running vintage or specialized software.

In conclusion, the Intel Xeon E5620 is best suited for legacy server environments, retro computing projects, or educational use. It is not competitive with current-generation processors but remains a notable example of early 2010s server architecture. Its performance, while outdated by today’s standards, reflects the capabilities of its time and provides a baseline for understanding advancements in CPU design over the past decade.
