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.
In addition, the Quad-Core Intel Xeon Processor 5400 Series supports the Execute Disable Bit functionality. When used in conjunction with a supporting operating system, Execute Disable allows memory to be marked as executable or non executable. This feature can prevent some classes of viruses that exploit buffer overrun vulnerabilities and can thus help improve the overall security of the system.
