About Intel Xeon E5450

The Intel Xeon E5450 is built on the 45 nm Harpertown microarchitecture, a derivative of the NetBurst design that implements a 4‑core, 4‑thread layout on the Socket 771 platform. Its 3.0 GHz base clock, combined with a 6 MB shared L2 cache, delivers respectable single‑thread throughput, as evidenced by a Cinebench R23 single‑core score of 308 points and a R20 single‑core result of 129 points. In multi‑core workloads the processor reaches 2,187 points in Cinebench R23 and 918 points in the older R20 suite, reflecting the modest scaling typical of a four‑core server chip from the 2007 era. With an 80 W thermal design power, the E5450 balances modest energy draw against its performance envelope, making it suitable for dense blade or rack‑mount servers where heat density must be managed. The chip supports dual‑channel DDR2‑667 memory up to 8 GB, and its memory controller, integrated into the northbridge, provides sufficient bandwidth for legacy database and virtualization workloads, though it cannot match the throughput of modern DDR4 designs. Consequently, the E5450 is best positioned for legacy enterprise applications, small‑to‑medium virtualization hosts, and compute‑intensive tasks that rely on stable, long‑term platform support rather than raw performance. For organizations maintaining older infrastructure, the E5450 Xeon offers a reliable, low‑cost solution that still delivers enough horsepower for many traditional server roles.
