The latest version of SiSoft Sandra offers up a lot of new features including GPU performance, OpenCL, etc.
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.
In the x264 benchmark, both the first pass and second pass results are consistant with what we expect from the 3770k.
This rendering benchmark based off of the Cinema 4D engine is a terrific indicator for multi-threaded processing.
TrueCrypt is one of the most popular pieces of software for disk encryption and it includes a handy benchmark mode to test the capabilities of your processor. Keep in mind that many modern CPUs include AES acceleration which is used throughout TrueCrypt.
While testing encryption within Truecrypt, which tends to showcase hyperthreading performance, the Z77A-GD80 provides expected results in both AES encryption and the average of all of the individual tests.
