Intel Xeon Harpertown

New Quad-Core Intel® Xeon® processor 5400 series-based servers, HPC systems, and workstations are built with 45nm enhanced Intel® Core™ microarchitecture, previously code-named “Penryn”. The Intel® 45nm technology uses high-k dielectric materials that are expected to fuel the ongoing performance advantages predicted by Moore’s Law for years to come, and significantly increases the transistor density over the previous Intel® 65nm technology.

Intel’s 45nm process packs a whopping 820 million transistors into the Intel® Xeon® processor 5400 series over the previous-generation Intel® Xeon® processor 5300 series, which had an astounding 582 million transistors.

Quad-Core Intel® Xeon® processor 5400 series-based server platforms deliver incremental headroom and performance for your two-processor general-purpose server, so you can confidently consolidate applications onto fewer systems with fewer cooling challenges, giving you more performance per square foot. Translation: lots of processor for your $.

Features	Benefits
