| General Benchmarks | Description | |
| Power Consumption | To emulate real-world usage scenarios, we record mains power draw both when idle and while playing Far Cry 3 | |
| Temperature | To emulate real-world usage scenarios, we record GPU core temperature both when idle and while playing Far Cry 3 | |
| Noise | A PCE-318 meter is used to record noise levels when idle and while playing Far Cry 3 | |
Notes
For the purpose of this evaluation, we're focussing specifically on the high-end by comparing the Inno3D iChiLL against single-GPU cards costing between £350-£800.
