Not much variance here. The 790GX manages to serve up a slightly faster time in our iTunes audio conversion. But the difference is small, at best.
We get similar results in our MainConcept video conversion test, where the 790GX wins, but only by a scant two seconds. The 780G board takes second place and is followed by Nvidia’s GeForce 8300 platform — separated again by only two seconds.
Blu-ray playback using PowerDVD is a light-duty affair with both AMD and Nvidia solutions. Using the quad-core Phenom X4 9850 CPU, we saw utilization numbers in the two percent range on the 790GX. The GeForce 8300 wasn’t much higher, nearly two and a half percent. Of course, as you shed processing power, the task becomes more demanding.
