SPEC marks of some NOT current CPUs.

SPEC marks are the most common means by which CPUs are benchmarked. They involve running a number of real world applications. These are generally considered fairly accurate but like any benchmarks do not tell the whole story.

KEY

MHz - CPU Clock speed in millions of cycles per second.
SPEC Int 95 - Benchmark result for interger processing.
SPEC fp95 - Benchmark result for floating point processing.
