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 platforms 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.

What is performance per system watt?
Performance per system watt is calculated by taking the performance score from a benchmark or application and dividing it by the average system power usage (AC power from the wall). The corresponding performance/power or performance per watt scores are normalized to a baseline platform for comparison purposes. In these measurements, the Intel® Xeon® processor 3.80GHz is the base platform (1.0).

Intel focuses on performance per watt comparisons using power measured at the system level as opposed to component level TDP or max power ratings. Measured system level power is a more accurate representation of the customer's true energy cost.

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.

SPECint*2000/SPECint*2006 and SPECfp*2000/SPECfp*2006 benchmark tests reflect the performance of the microprocessor, memory architecture and compiler of a computer system on compute-intensive, 32-bit applications. SPEC benchmark tests results for Intel® microprocessors are determined using particular, well-configured systems. These results may or may not reflect the relative performance of Intel® microprocessor in systems with different hardware or software designs or configurations (including compilers). Buyers should consult other sources of information, including system benchmarks; to evaluate the performance of systems they are considering purchasing.

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 www.intel.com/products/processor_number for details.
