Intel Xeon Processor X5550 (8M Cache, 2.66 GHz, 6.40 GT/s QPI) 8MB Smart Cache

Performance. Efficiency. Agility.Intel’s newest dual-core processor for dual processor (DP) servers and workstations delivers a new level of energy-efficient performance from the innovative Intel® Core™ microarchitecture, optimized for low-power, dual-core, 64-bit computing.The Dual-Core Intel Xeon processor 5100 series is ideal for intense computing environments, 32-bit and 64-bit business-critical applications and high-end workstations. Combined with the Intel® 5000 chipset family and Fully Buffered DIMM (FBDIMM) technology, the new Dual-Core Intel Xeon processor 5100 series-based platforms are expected to deliver up to 3 times the performance and 3.5 times the performance/watt of previous-generation single-core Intel® Xeon® processors. The new Dual-Core Intel Xeon processor 5100 series-based platforms are expected to deliver up to 2.25 times the performance and 2.35 times the performance/watt of previous-generation dual-core Intel Xeon processors.The Dual-Core Intel Xeon processor 5100 series is compatible with Intel® 5000P, 5000V and 5000X series of chipsets. Server boards based on these chipsets are optimized for dual core with advanced platform features of Dual Independent Bus and Fully Buffered DIMM memory technology offering up to 4X and 3X available bandwidth of current generation platforms. Improved I/O performance is possible with PCI Express* and the option of Intel I/O Acceleration Technology.Dual-core processingSignificant performance
