Intel's Turbo Boost technology provides a mechanism for improving system performance most significantly in lightly-threaded apps, even at peak loads. But what is the feature's impact on a Gulftown-based Core i7-980X processor with different core counts?

Benchmark Results: Audio/Video

We’ve said repeatedly that iTunes wasn’t thread-optimized. It appears that this statement isn’t entirely accurate. The app is multi-threaded, but the "benefit" is pathetic.

The Lame MP3 encoder is also better off with a fast dual-core rather than a massive six-core processor.

MainConcept and HandBrake for video transcoding both scale well with additional CPU cores.
