Benchmark Results: Media Encoding
The iTunes benchmark is our only audio-encoding test, and the new system snags an easy win here with stock performance besting the previous system’s overclock.
Of course, because we know that iTunes is single-threaded, we can be relatively sure that the Sandy Bridge-based system's win is attributable to a combination of its high clock rates and improvements to its IPC throughput.
These three video encoding applications deliver the same result as iTunes: the overclocked Core i5-750 barely meets stock Core i5-2500K performance levels, and the new processor shows a huge improvement when pushed past its stock specification.
