Just before Christmas, Dan and I took delivery of a dual core and a quad core machine, and we thought we’d see if it’s actually worth putting four cores into your computer, rather than two. We ran four processor-intensive concurrent tasks – a virusscan, a DVD encode, a 3D game, and then we measured how long it took to unzip a zip file.

The results? Well, you’ll have to watch the video to find out. I’ll just say that I was surprised by the outcome. Let us know your experiences of Quad core vs Dual core chips in the comments below.
