SPEC - Processor Benchmarks

A computer benchmark is typically a computer program that performs a strictly defined set of operations (a workload) and returns some form of result (a metric) describing how the tested computer performed. Computer benchmark metrics usually measure speed (how fast was the workload completed) or throughput (how many workloads per unit time were measured). Running the same computer benchmark on multiple computers allows a comparison to be made.

SPEC^® is an acronym for the Standard Performance Evaluation Corporation, a non-profit organization composed of computer vendors, systems integrators, universities, research organizations, publishers and consultants whose goal is to establish, maintain and endorse a standardized set of relevant benchmarks for computer systems. Although no single set of tests can fully characterize overall system performance, SPEC believes that the user community will benefit from an objective series of tests which can serve as a common reference point.

SPEC CPU2000 is the next-generation industry-standardized CPU-intensive benchmark suite. SPEC designed CPU2000 to provide a comparative measure of compute intensive performance across the widest practical range of hardware. The implementation resulted in source code benchmarks developed from real user applications.

SPEC CPU2000 focuses on compute intensive performance, which means these benchmarks emphasize the performance of:

• the computer's processor (CPU),
• the memory architecture, and
• the compilers.

It is important to remember the contribution of the latter two components; performance is more than just the processor.

CFP2000 is a subcomponent of SPEC CPU2000 which measures and compares compute-intensive floating point performance. Aspen Systems recommends the SPEC CPU2000 CFP2000 benchmarks as a good measure for high-performance systems.

Aspen Systems has compiled a comparison of peak SPEC CPU2000 rates for processors used in our high-performance systems. The charts and tables compare SPEC peak values for speed (CINT2000, CFP2000) and throughput (CINT2000 Rate, CFP2000 Rate).
