The only test here that shows a noticeable difference in the results is the Light-04 test, which has the AMD 760 just about 3% faster than the KT266, though they are both above the KT133A A7V133. More results like this are showing that DDR is becoming the mainstream option.
While the read scores on par for both DDR chipsets, for some reason the write speed on the KT266 falls dramatically behind: about 40%. While the effects of this aren’t exactly evident from the tests that we have run here, my personal feelings are that read speed is much more important than write. The most common bottleneck in CPU speed is reading in data from memory, not writing to it from the hard disk.
The KT266 chipset pulls just ahead on this atomic-synthesis test. Notice that the KT133A is still very close to these results. Obviously, then, the benchmark is much more CPU intense than memory speed.
