Phenom II X4 970 and Phenom II X6 1075T 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 the Phenom II X4 970 and the Phenom II X4 965 achieved similar performance, with the Core i5-750 being 15% faster than the Phenom II X4 970. The Phenom II X6 1090T was only 4% faster than the new Phenom II X6 1075T, but the Core i5-750 was 14% faster than this new CPU.
