Processor Performance Comparisons -SPEC 95
Below you will find various processor comparisons for PowerPC and Intel based chips. Testing was done using SPEC 95 the industry standard for measuring raw processor performance and scores are based on the manufacturer's published results.
The results directly below were obtained by using the benchmarking program SPECint 95 which measure Integer intensive tasks
The results below were obtained by using the benchmarking program SPECfp 95 which measures Floating Point intensive tasks

SPEC, the Standard Performance Evaluation Corporation, is a non-profit corporation formed to "establish, maintain and endorse a standardized set of relevant benchmarks that can be applied to the newest generation of high-performance computers" (quoted from SPEC's bylaws). The founders of this organization believe that the user community will benefit greatly from an objective series of applications-oriented tests, which can serve as common reference points and be considered during the evaluation process. While no one benchmark can fully characterize overall system performance, the results of a variety of realistic benchmarks can give valuable insight into expected real performance.
SPEC is a non-profit corporation registered in California.
SPEC basically performs two functions:
SPEC develops suites of benchmarks intended to measure computer performance. These suites are packaged with source code and tools and are extensively tested for portability before release. They are available to the public for a fee covering development and administrative costs. By license agreement, SPEC members and customers agree to run and report results as specified in each benchmark suite's documentation. SPEC publishes news and benchmark results in The SPEC Newsletter and The GPC Quarterly. Both are available electronically through http://www.spec.org/ (and available in paper as a quarterly publication if necessary) this provides a centralized source of information for SPEC benchmark results.
SPEC95 refers to the total SPEC95 product provided by SPEC. SPEC95 is composed of two suites of benchmarks:
These are intended to provide a measure of compute-intensive performance of the processor, memory hierarchy and compiler components (the 'C' in CINT95 and CFP95) of a computer system for comparison purposes.
