Athlon II X4 620 CPU Review
VirtualDub + DivX
Contents
With VirtualDub we converted a full-length DVD movie to DivX format and saw how long it took for this conversion to be completed. The DivX codec is capable of recognizing and using not only more than one CPU (i.e., more than one core), but also the SSE4 instruction set (feature not available on the reviewed CPUs).
The movie we chose to convert was Star Trek – The Motion Picture: Director’s Cut. We copied the movie to our hard disk drive with no compression, so the final original file on our HDD was 6.79 GB. After compressing it with DivX, the final file was only 767.40 MB, which is quite remarkable.
The results below are given in seconds, so the lower the better.
On DivX encoding using the on-board video Athlon II X4 620 was 26.47% faster than Pentium E6300. Installing a GeForce 9600 GT increased encoding performance but Athlon II X4 620 wa
s still faster than Pentium E6300 by 21.41%.
