| General Benchmarks | Description | |
| 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
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.
