Intel® Xeon® Processor 5400 Series: Datasheet
The quad-core Intel® Xeon® processor 5400 series is a server/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 low-power microarchitecture. The quad-core Intel® Xeon® processor 5400 series maintains 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 processors’ Data Prefetch Logic speculatively fetches data to the L2 cache before an L1 cache request occurs, resulting in reduced effective bus latency and improved performance. The 1066 MHz Front Side Bus is a quad-pumped bus running off a 266 MHz system clock making 8.5 GBytes per second data transfer rates possible. The 1333 MHz Front Side Bus 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 is a quad-pumped bus running off a 400 MHz system clock making 12.80 GBytes per second data transfer rates possible.
Enhanced thermal and power management capabilities are implemented including Intel® Thermal Monitor 1, Intel® Thermal Monitor 2 and Enhanced Intel SpeedStep® Technology. These technologies are targeted for dual processor configurations in enterprise environments. Intel® Thermal Monitor 1 and Intel® Thermal Monitor provide efficient and effective cooling in high temperature situations. Enhanced Intel SpeedStep Technology provides power management capabilities to servers and workstations.
