Multi-tasking test and overall score

multitasking 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.
