General Benchmarks
Power Consumption To emulate real-world usage scenarios, we record mains power draw both when idle and while playing Batman: Arkham City
Temperature To emulate real-world usage scenarios, we record GPU core temperature both when idle and while playing Batman: Arkham City
Noise A PCE-318 meter is used to record noise levels when idle and while playing Batman: Arkham City

Notes

We're using this review as an opportunity to introduce a new test platform and a refreshed benchmark suite. Our trusty-ol' Sandy Bridge rig has been retired in favour of a new Ivy Bridge system that consists of an Intel Core i7-3770K processor, a Gigabyte GA-Z77X-UD5H motherboard and 8GB of G.Skill memory. DiRT Showdown and LuxMark 2.0 have been added to the benchmark suite.

In the interests of fairness, any GPU vendor-specific technologies are disabled during benchmarking. For example, NVIDIA-exclusive features such as PhysX in Batman: Arkham City and the Bokeh Filter in Just Cause 2 are not enabled.
