The CPU Scorecard
benchmark score for the G4 was originally based on Apple's published test,
as linked to our Benchmark Links page.
However, this test was optimised to exploit the G4's new Velocity Engine
technology, supporting Apple's "supercomputer" marketing claim
and showing how the G4 can run almost three times faster than a Pentium.
Other tests have since pointed out the strong performance of the
G4--particularly in floating-point calculations--but without the VE
optimisations. Without VE, the performance advantage of the G4 is still
evident, just not quite as high. VE will not provide the same performance
boost for those applications not specifically written to take advantage of
its instruction set. Therefore, The CPU Scorecard G4 score now
incorporates the more recent non-VE tests along with the original VE
scores to provide a kind of average 'real world' estimate of its speed.
As new benchmarks are published and updated, the CPU
Scorecard scores are often adjusted and tweaked to provide the most
relevant and accurate processor comparisons anywhere.
