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.

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.

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.

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.
