The Intel Xeon Processor MP is exclusively designed for enterprise server workloads and provides significant productivity gains over previous IA-32 server platforms. The combination of Intel NetBurst microarchitecture, Hyper-Threading Technology and integrated Three Level Cache subsystems provide the performance and scalability required for demanding enterprise applications and strategic consolidation projects. These breakthroughs enable innovative and enhanced processor execution allowing the processor to run at twice the core frequency, thereby executing machine instructions in one half of the internal core clock cycle. These technology advances provide tangible server applications productivity increases in the area of transaction processing, support for additional end users and faster response time for Web sites and e-business applications. The scalability of the Intel Xeon Processor MP allows businesses to derive optimal business value by investing in fully populated IBM eServr xSeries server platforms. By taking advantage of the performance, flexibility and compatibility of this new Xeon Processor MP, businesses can closely match each server-unique solution to specific application and business requirements. The result is a more cost-effective infrastructure and a standards-based computing environment that can adapt quickly to changing needs. The additional performance headroom and scalability features of MP-based servers offer unique performance advantages over dual-processor or cluster-based servers.This processor is not supported on the following IBM eServer xSeries 445 models: 8870-1RX, 8870-2RX, 8870-4RX, 8870-3RY, 8870-4RY, 8870-1AX, 8870-2AX, 8870-4AX.
