Audio and Video Encoding

We see pretty similar results during video encoding tests. All contemporary codecs can really take advantage of multi-core processor features. They also get a boost from faster bus between the processor and memory subsystem. As a result, Core 2 Extreme QX6850 is a leader during video encoding tests.

As for the audio encoding with Apple iTunes, the situation here is a little different. The thing is that this codec can only create two threads at the same time, which doesn’t make the use of quad-core CPUs as efficient as it could be. However, despite this fact, Kentsfield processors can still ensure a performance boost over Conroe thanks to larger L2 cache.
