New speed testing program | |
Here is a new version of the speed testing program. This one allows the pipeline to fill up and as such will give different results than before. This test seems to run a lot better for me which suggests the the P4 pipeline is quite nasty for floating point.
Here are my numbers for the new program (1.8Ghz P4)
Integer: 1.462
Single: 1.311
Double: 1.292
As you can see, the numbers are a lot closer now. This makes floating point worth it.
PS: The attached program was compiled unoptimized and compiled for a 386 so anyone should be able to run it. If compiled optimized the three numbers are basically equal. |
