GENERAL NOTES: -Displayed CPU speed may be wrong with some custom CPU. Exec returns my 1.4Ghz G4 to run 400Mhz. MIPS NOTES: -Benchmarking MIPS is NEVER relevant. From a benchmark to another, the loop used is not the same, giving different results. -Benchmarking MIPS is in most case optimised for a particular CPU, and irrelevant for a CPU with a different architecture. -The real "maximum MIPS" capability of a CPU can be known just with its datasheet, without any benchmark. It's "CPU Frequency * Instruction dispatcher outs". -This is the value I try to bench. IU32 vs FPU64 NOTES: -Since v0.37, benchmarks are done two times. Integer 32 and Floating point 64. -Depending of the benchmak done (L1, L2, Memory...), of CPU architecture, of bus bandwidth, sometime IU32 is faster, sometime it's FPU64. AONE NOTES: -Some people use SetA1. Superb tool, thanks to its author! -ECC ram are a bit slower. HISTORY v0.37 -Added a small MIPS benchmark. -Now bench with IU32 and FPU64 instead of only FPU64. -Maybe the "Slow L1" problem on Sam440 is solved. v0.36 -Tryed something different for the video bus speed, results may differ a bit from older versions. -The way I use to read/write video memory is very crap, but at least it should work this time. (I hope so) (really...) (sigh) v0.35 -DO NOT USE ANYMORE THIS PRIVATE VERSION, RESULTS ARE WRONG! v0.34 -First release |
