Performance Summary
It looks like the new e6750/8800 GTS 320 MB combo enjoys an advantage over the e4300/8800 GTX combo, but this isn't really true: at 1600x1200 and above, the 8800 GTX will perform better, even when paired with a slower CPU. This will become more apparent in our summary article, when our e6750/8800 GTS 320 MB goes up against the midrange system, which sports an 8800 GTX.
There's no special interpretation to be made here: the e6750 CPU performs software applications at about one-and-a-half times the speed of the e4300. This is an incredible speed difference, one that really matters in real-world applications.
The synthetic benchmark summary is a little fudged, because we don't have proper results for PcMark 2005 - as we stated, we couldn't get a total system score due to a benchmark glitch. We brought down the new system's average score by assigning it an arbitrary 100% compared to the old system, even though its actual score would likely have been much higher. Even with this artificial handicap, though, the PcMark results were on average 133% faster than the old system.
3dMark 2005 is a synthetic graphics benchmark, and tells pretty much the same story as actual gaming benchmarks did. Looking to Specviewperf and Sisoft Sandra, we see the same 150% performance numbers from the new system that we saw in the application benchmarks.
When we average everything out for a figure to represent the overall performance of the new system vs. the old system, we get a figure of 136%. The interesting part is that the new system costs less than the old one! This will make for an interesting value analysis indeed.
