Intel® Xeon® processor 3300 series-based servers: Optimized for small business, these value-priced processors with moderate DDR2 memory platform capacity make this ideal as a first small business server.

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.

Benchmark description for SPECpower_ssj*2008: New industry-standard benchmark for measuring energy efficiency of volume servers using a Server-side Java* application (similar to SPECjbb*2005). The graduated workload measures AC system power consumption in relation to performance and is reported as overall ssj_ops / watt result.

Configuration details: Published SPECpower_ssj*2008 benchmark results as of April 4, 2008:

Intel® Xeon® Processor 3300 series-based servers: Optimized for small business, these value-priced processors with moderate DDR2 memory platform capacity make this ideal as a first small business server.

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 3085 3.0GHz 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.

Benchmark description for Fluent*: Fluent is a commercial engineering application used to model computational fluid dynamics. The benchmark consists of nine standard workloads organized into small, medium and large models. These comparisons use all but the largest of the models which does not fit into the 8GB of memory available on the platforms. The Rating, the default Fluent metric, was used in calculating the ratio of the platforms by taking a geometric mean of the eight workload ratings measured.

Configuration details: Internally measured Fluent version 6.3.33 (eight of the nine standard, jobs/day) benchmark results as of January 7, 2008.

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.
