Here is a email to tom and his response . These is a honest test that I did and I get different results from Tom on the performance beteen intel and amd cpu . This was snet to Tom and he did not seem to like it too much . See for yourself
PS. If you would like an exe and source code for the benchmark email me at yvonbou@videotron.ca
Hello Tom
Here are the test results on my system
Pentium II 450 MHz, ASUS P2B-F
Execution time: 68.739723 ms (nPixel: 1048576)
Execution time: 29.851272 ms (nPixel: 524288)
Execution time: 14.981788 ms (nPixel: 262144)
Execution time: 7.431389 ms (nPixel: 131072)
Execution time: 3.676723 ms (nPixel: 65536)
Execution time: 1.711390 ms (nPixel: 32768)
Execution time: 0.496152 ms (nPixel: 16384)
Execution time: 0.257295 ms (nPixel: 8192)
Athlon Thunderbird 1 GHz, ASUS A7V motherboard
Execution time: 87.334843 ms (nPixel: 1048576)
Execution time: 41.203840 ms (nPixel: 524288)
Execution time: 20.452879 ms (nPixel: 262144)
Execution time: 10.227277 ms (nPixel: 131072)
Execution time: 5.110985 ms (nPixel: 65536)
Execution time: 2.562616 ms (nPixel: 32768)
Execution time: 1.129473 ms (nPixel: 16384)
Execution time: 0.372394 ms (nPixel: 8192)
Here is the test software exe and source code . This allocates a buffer and does a mmx funtion between 4 source buffers and writes the result to a destination buffer. The function does image lookup function then a recursive average .

Subject: RE: Your Benchmarks results
How can my test show different results from yours if you are actually using proprietary benchmarking software that is unavailable to me? A different benchmark gives different results and in fact I am trying to stick to real world benchmarks as much as I can.
I don't apprecaite your slight implication that my testing would not be reliable. What claims to fame in terms of benchmarking have you got ?
Regards,
Tom

Hello Tom
I am an avid reader of your reports. I work in the image processing field and use embedded pentiums. We recently looked athlon 1 Ghz AMD and ran our image processing code . On raw memory access the AMD with the VIA 100mhz FSB required twice as many CPU clock cycles as the INTEL 933mhz 815 system. The MMX image processing functions also require 50 % more time on the AMD . I do not favor one or the other but my tests show a different result from yours . If you are interested I will email executables and source code of these simple tests . I am curious to why I see this discepency between what you note and what I can measure .
