45nm Intel® Xeon® Processors 5400/5200 Series: Brief
These Intel® Xeon® processors, with extended lifecycle support, utilize Intel’s Hafnium-based 45nm Hi-k silicon process technology to reduce power consumption, increase switching speed, and significantly increase transistor density over previous 65nm technology to 820 million transistors. The Intel® Xeon® processor E5440 delivers a 27 percent performance gain within the same thermal profile over the previous-generation Intel® Xeon® processor E5345, making it an excellent choice for compute-intensive embedded, storage, and communications applications.
Lower thermal design power and higher Tcase temperature options are ideal for low-power consumption and/or compliance with the AdvancedTCA* form factor and NEBS level-3 thermal specifications. The Intel® quad-core processor 5400 series supports 12 MB on-die L2 cache (2x6 MB) and the Intel® dual-core processor 5200 series supports 6 MB on-die L2 cache. All processors integrate Intel® Virtualization Technology (Intel® VT), Intel® 64 architecture, Intel® VT FlexMigration, and Intel® VT FlexPriority.
These quad- and dual-core processors utilize a common microarchitecture and common socket with the previous generation Intel® Xeon® processor 5300 series and 5100 series, providing a simplified path to upgrades.
