Intel Core 2 Extreme QX9650 Quad Core CPU
Compression & Encoding Benchmarks
ViMark is designed to take the inaccuracies and guesswork out of measuring the time taken to encode video files, and produces easily comparable and consistent results for encoding raw video into Windows Media, Quicktime, AVI and Gif formats. As always, a total of 5 benchmark runs were performed with the highest and lowest scores removed and an average calculated from the remaining 3 scores.
With the E6850 matching the performance of the QX9650 in both the GIF, AVI and Quicktime benchmarks, it's clear to see that these specific encoding routines do not support symmetrical multiprocessing. Windows Media on the other hand shows significant performance increases for both the QX9650 and the Q6600 over the E6850, with the increased clock speed and cache of the QX9650 allowing it to take quite a substantial lead.
7-Zip is an open source winzip-style file compression utility that has the ability to compress and decompress many file formats including its own .7z compression scheme. 7-Zip also comes complete with its own benchmarking utility for gauging the compression and decompression speed of the system that it is installed on.
Yet again the E6850 and QX9650 are on similar ground, quite possibly indicating that 7-Zip isn't multi-threaded. However, even with the 7-Zip not making full use of the processing power available, the extra cache and other optimizations of the QX9650 allow it to gain a significant lead over the other processors in the compression benchmark.
