New Quad-Core Intel® Xeon® processor 5400 series based servers: New Quad-Core Intel Xeon processor 5400 series based servers, HPC systems, and workstations are built with 45nm enhanced Intel® Core™ microarchitecture previously code-named "Penryn." The Intel® 45nm technology uses high-k dielectric materials that are expected to fuel the ongoing performance advantages predicted by Moore's Law for years to come, and significantly increases the transistor density over the previous Intel® 65nm technology. This second generation Quad-Core Intel Xeon processor 5400 series based platform extends the performance, energy-efficiency and virtualization leadership established by the Quad-Core Intel® Xeon® 5300 series. The breakthrough performance, energy efficiency and reliability of the new Quad-Core Intel® Xeon® processor-based systems make them the best choice for virtualization and business critical applications, enabling IT to become more efficient and responsive.

Performance tests and ratings are measured using specific computer systems and/or components and reflect the approximate performance of Intel® products as measured by those tests. Any difference in system hardware or software design or configuration may affect actual performance. Buyers should consult other sources of information to evaluate the performance of systems or components they are considering purchasing. For more information on performance tests and on the performance of Intel products, visit Intel Performance Benchmark Limitations.

Relative performance for each benchmark is calculated by taking the actual benchmark result for the first platform tested and assigning it a value of 1.0 as a baseline. Relative performance for the remaining platforms tested was calculated by dividing the actual benchmark result for the baseline platform into each of the specific benchmark results of each of the other platforms and assigning them a relative performance number that correlates with the performance improvements reported.

64-bit Intel® Xeon® processors with Intel® EM64T requires a computer system with a processor, chipset, BIOS, OS, device drivers and applications enabled for Intel EM64T. Processor will not operate (including 32-bit operation) without an Intel EM64T-enabled BIOS. Performance will vary depending on your hardware and software configurations. Intel EM64T-enabled OS, BIOS, device drivers and applications may not be available. Check with your vendor for more information.

Intel® processor numbers are not a measure of performance. Processor numbers differentiate features within each processor series, not across different processor sequences. See http://www.intel.com/products/processor_number for details.
