Benchmark description for SPECpower_ssj*2008
SPECpower_ssj2008* is the first industry-standard SPEC* benchmark that evaluates the power and performance characteristics of volume server class computers. The benchmark uses a graduated workload using server side Java* to measure server performance in relation to power at 11 different load levels, from 100 percent load down to idle in ten percent increments. For more information, refer to http://www.spec.org/power_ssj2008/.

Benchmark description for SPECint*_rate_base2006
SPECint_rate_base2006 is a compute-intensive benchmark that measures the integer throughput performance of a computer system carrying out a number of parallel tasks. The benchmark consists of a suite of twelve integer workloads developed from actual end-user applications. System throughput is measured by running multiple copies of the benchmark simultaneously with the number of copies typically set to the number of logical hardware cores seen by the operating system. The performance score reported is a measure of the throughput of the system measured in jobs/hour. Higher score indicates better performance.

Benchmark description for SPECfp*_rate_base2006
SPECfp_rate_base2006 is a compute-intensive benchmark that measures the floating point throughput performance of a computer system carrying out a number of parallel tasks. The benchmark consists of a suite of seventeen floating point workloads developed from actual end-user applications. System throughput is measured by running multiple copies of the benchmark simultaneously with the number of copies typically set to the number of logical hardware cores seen by the operating system. The performance score reported is a measure of the throughput of the system measured in jobs/hour. Higher score indicates better performance.
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.
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 www.intel.com/performance/resources/benchmark_limitations.htm.
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® microprocessors 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 require 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 family, not across different processor families. See www.intel.com/products/processor_number/ for details.

Intel encourages all of its customers to visit the referenced Web sites or others where similar performance benchmarks are reported and confirm whether the referenced benchmarks are accurate and reflect performance of systems available for purchase.
