Benchmarks
Sisoft Sandra 99" (Dhrystone)
According to the Sisoft FAQ: The Sandra Dhrystone
benchmark is still widely used to measure CPU performance in industry under
various versions/variants. The benchmark is designed to contain a representative
sample of types of operations, mostly numerical, used by applications. Unfortunately
this does not always represent a true real-life performance, but is useful
to compare the speed of various CPUs. The Dhrystone benchmark used here is
a 32-bit variant of the original one which runs under UNIX. The result is
determined by measuring the time it takes to perform some sequences of instructions.
Due to various changes, the result is not directly comparable with other Dhrystone
benchmarks. However the MIPS (Million Instructions Per Second) should be the
same for the same system (+5-10% variation) between benchmarks. While the
original benchmark does not compute anything, this version does check the
results with the expected ones just in case there are problems with the CPU/memory.
Sisoft Sandra 99 (Whetstone)
According to the Sisoft FAQ: The Sandra Whetstone
benchmark is widely used in the computer industry as a measure of FPU or Co-Processor
performance. Floating-point arithmetic is most significant in programs that
require a Co-Processor. These are mostly scientific, engineering, statistical
and computer-aided design programs. The Whetstone benchmark used here is a
32-bit variant of the original one which runs under UNIX. The result is determined
by measuring the time it takes to perform some sequences of floating-point
instructions. Due to various changes, the result is not directly comparable
with other Whetstone benchmarks. However the MFLOPS (Million FLoating OPerations
per Second) should be the same for the same system (+5-10% variation) between
benchmarks
ZDnet CPUmark 99
According to Zdnet: CPUmark 99 is a subsystem-level
test that measures the speed of a PC's processor subsystem, which includes
the CPU, its internal cache (both level one and/or level two), external cache,
and system RAM.
