How we test

Overall score includes:

Performance (50%)
Design and use (30%)
Display (20%)

The tests we use to measure a computer's performance reflect everyday usage. Our tests look at processor and graphics performance as well as memory and storage. We compare a computer’s performance using cross-system benchmarking software to test and compare on different operating systems, such as Windows 10 and macOS Sierra.

Design and use is split into a tester assessment (40%) and an expert panel assessment (60%). The tester assessment consists of testing the recovery options, screen adjustment, manuals and information and sound quality. Our panel of three professional users assess the design, style, and keyboard and mouse use.

Display is assessed on colour, brightness and contrast (55%); glare/surface reflections (20%); viewing angle where applicable (10%); and blu-ray playback where applicable (15%).
