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.
