PowerPC vs Intel: G3/450Mhz
Dukes It Out With The Pentium III/550Mhz. And The Winner Is......
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:
SPEC
CINT95: a set of eight compute-intensive integer/non-floating
point benchmarks SPEC
CFP95: a set of 10 compute-intensive floating point 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.
