HP 459489-L21 Processor Computer Component

The Quad-Core Intel® Xeon® Processor 5400 Series is a workstation processor utilizing four 45-nm Hi-k next generation Intel® Core™ microarchitecture cores. The processor is manufactured on Intel's 45 nanometer process technology combining high performance with the power efficiencies of a low-power microarchitecture. These processors maintain the tradition of compatibility with IA-32 software. Some key features include on-die, primary 32-kB instruction cache and 32-kB write-back data cache in each core and 12 MB (2 x 6MB) Level 2 cache with Intel® Advanced Smart Cache Architecture. The 1333 MHz Front Side Bus (FSB) is a quad-pumped bus running off a 333 MHz system clock making 10.66 GBytes per second data transfer rates possible. The 1600 MHz Front Side Bus (FSB) is a quad-pumped bus running off a 400 MHz system clock making 12.80 GBytes per second data transfer rates possible. Quad-Core Intel Xeon Processor 5400 Series supports Enhanced Intel SpeedStep® Technology. This technology enables the processor to switch between multiple frequency and voltage points, which results in platform power savings.
