Introduction
The Dual-Core Intel® Xeon® Processor 5000 series are Intel dual core products for dual processor (DP) servers and workstations. The Dual-Core Intel Xeon Processor 5000 series are 64-bit server/workstation processors utilizing two physical Intel NetBurst® microarchitecture cores in one package. The Dual-Core Intel Xeon Processor 5000 series include enhancements to the Intel NetBurst microarchitecture while maintaining the tradition of compatibility with IA-32 software. Some key features include Hyper Pipelined Technology and an Execution Trace Cache. Hyper Pipelined Technology includes a multi-stage pipeline depth, allowing the processor to reach higher core frequencies. The Dual-Core Intel Xeon Processor 5000 series contain a total of 4 MB of L2 Advanced Transfer Cache, 2 MB per core. The 1066 MHz Front Side Bus (FSB) is a quad-pumped bus running off a 266 MHz system clock making 8.5 GBytes per second data transfer rates possible. The 667 MHz Front Side Bus (FSB) is a quad-pumped bus running off a 166 MHz system clock making 5.3 GBytes per second data transfer rates possible.
