Auto GK allows us to convert movies to Divx format, a task that is quite common for many enthusiasts. It is also a key test for us because it requires a large amount of CPU attention. The Athlon 64 X2 6000+ takes advantage of the 200 MHz it has over the Athlon X2 5600+, and succeeds in pulling ahead of the Intel Core 2 Duo E6400.

Although 7-Zip can take advantage of dual-cores, it does not benefit from the additional cores the QX6700 has to offer. 7-Zip performs faster with Intel Core 2 Duo solutions; however, the margin of difference over Athlon 64 X2 processors is smaller than it was for the Auto GK test.

Lame MT is a tool that converts from Wav to MP3. Although the utility has a command line interface, it can still take advantage of multiple cores, but it still doesn't benefit from the added horsepower of the QX6700. The tests were run at a constant bit rate using the Intel compiler. Here, the Athlon 64 X2 6000+ performs on par with the Core 2 Duo E6400.

In iTunes we converted a 613 MB audio file from WAV to MP3 192Kbps. Similar to the Lame MT test, the new AMD processor ends up with conversion times equal to that of the Core 2 Duo E6400.
