Media Encoding

 

Handbrake


Known mainly for its DVD re-encoding prowess, our test uses the Handbrake command line interface on a full DVD rip to gauge CPU performance.

Interestingly, the Core i7-3770K runs a bit faster in our Handbrake testing when we disable HyperThreading to simulate the Core i5-3570 CPU; the same is seen with the 2600K/2500 scenario.  Still, the new Ivy Bridge processor is faster than the Core i7-3820 and within a reasonable margin of the 6-core 3960X.

 

x264 HD Benchmark


The popular x264 benchmark available from graysky does a two-pass H.264 encode on 720p video.  The first pass appears to be more clock sensitive while the second pass is more heavily threaded.

The first pass shows the same kind of results that Handbrake did – higher performance with HyperThreading disabled.  The second pass is very different though as we see nearly a 20% gain in performance by enabling it.  The i7-3770K is 16% faster than the i7-2600K and 11% faster than the Core i7-3820 SNB-E.
