AMD 890GX Unveiled: Three Motherboards Compared

Benchmark Results: Audio And Video Encoding

Apple's iTunes encoder responds almost exclusively to CPU clock speed, so we expect to see little to no performance difference, regardless of chipset.

The older board strangely falls behind in Handbrake, but most users wouldn’t notice a difference this small.

TMPGEnc and MainConcept get no benefit from the new chipset.
