I just got a Core 2 Duo E6700 and noticed the results from another machine. Mine scored much lower at MMX in Windws 7. I tried Windows VIsta 32 HP clean install and got about 82,000 like normal. In clean installs of Win7 HP 32 & 64 bit i get around only 25,000. Is HWINFO32 misreporting?
Note: I can't seem to upload all the files that I want to.
I'm not sure what this problem could be, but I have already seen quite big differences between results (especially in MMX score) on different operating systems XP - Vista - Win7. There are certainly differences to memory management between various systems, but I wouldn't expect such big difference.
What microcode difference you mean - the CPU Microcode Update Revision reported?
I don't have an explanation for this discrepancy and I don't see a reason why should HWiNFO32 misreport the results.
The code used in the MMX benchmark is a part of Gouraud shading algorithm implemented using MMX instruction set.
