Custom PC Media Benchmarks 2007

Gimp and Handbrake tests

Download from: www.custompc.co.uk/benchmarks

Custom PC, bit-tech's sister magazine, has developed its own Media Benchmarks to simulate the tasks that most of us perform on a regular basis. There are three tests, each of which measure different aspects of a PC's performance.

You can download the suite from the link above, and submit your score to the benchmark leaderboard to see how your PC compares with those of others.

The scores are normalised against a reference PC that includes a stock-speed Core 2 Duo E6700, 2GB of DDR2 memory and a fast P45 motherboard, as you can see below. This PC scores 1,000 points, so if your PC scores 1,300, it's 30 per cent faster than the reference system, and if it scores less than 1,000 points, it's slower.

Intel Core i5 and Core i7 Lynnfield review Image Editing and Video Encoding

Image editing with Gimp

Website: www.gimp.org

Far from being some kind of pr0n-filtering tool, Gimp is an open source image editing application - Gimp is an acronym of GNU Image Manipulation Program. Our test simulates how well a PC can manipulate a collection of large digital photos, and to achieve a low time requires a PC with a powerful CPU, plenty of quick memory and efficient hard disk drive access.

Video encoding with Handbrake

Website: http://handbrake.fr

We use the open-source, GPL-licensed, multi-platform, multi-threaded video encoder Handbrake to encode a HD video using the H.264 codec. This primarily tests multi-threaded CPU and memory subsystem performance.
