We have developed our own suite of benchmarks using real-world and open source applications to simulate how PCs are actually used. The suite comprises an image editing test using Gimp, a video encoding test using Handbrake and a multi-tasking test using 7-Zip to archive and encrypt a large batch of files while a HD movie plays in mplayer.

A score of 1,000 means that the test system is as fast as our reference PC, which used a 2.66GHz Intel Core 2 Duo E6750 at stock speed, 2GB of Corsair 1,066MHz DDR2 memory, a 250GB Samsung SpinPoint P120S hard disk and an Asus P5K Deluxe WiFi-AP motherboard. The scoring is linear, so a system scoring 1,200 points is 20 per cent faster than our reference system. Equally, a system scoring 1,200 is 4 per cent faster than a system scoring 1,150.

Multi-tasking with 7-Zip and mplayer

Websites: www.7-zip.org and www.mplayerhq.hu

Multi-tasking is a phrase that we're all familiar with, because most of us are now used to running multiple applications at the same time. However, to run multiple applications well you need a powerful (ideally multi-core) CPU and plenty of RAM.

Our multi-tasking test performs a massive file backup (with encryption) using 7-Zip, while simultaneously playing back a HD movie file using mplayer, making it a demanding test for any PC.

Overall Score


The overall score is an unweighted mean average of the scores of the three individual tests. A score of 1,000 means that the test system is as fast as our reference PC, which used a 2.66GHz Intel Core 2 Duo E6750 at stock speed, 2GB of Corsair 1,066MHz DDR2 memory, a 250GB Samsung SpinPoint P120S hard disk and an Asus P5K Deluxe WiFi-AP motherboard. The scoring is linear, so a system scoring 1,200 points is 20 per cent faster than our reference system. Equally, a system scoring 1,200 is 4 per cent faster than a system scoring 1,150.
