Temperature To emulate real-world usage scenarios, we record GPU core temperature both when idle and whilst playing Just Cause 2.
Noise A PCE-318 noise level meter is placed at front of a Corsair 600T chassis with side panel on.

Notes

We've grouped together as many mainstream GPUs as we could get our mitts on. While not directly comparable, we've thrown in the next model up from both AMD and NVIDIA - HD 6790 and GTX 550 Ti, respectively.

It's more than a little unfair to put the HD 6450 through this mid-range wringer, but we do it to see what a genuinely entry-level card makes of quality settings at 720p and 1080p resolutions.
