Using CyberLink PowerDVD 9, we playback 20 minutes of Pirates of the Caribbean: At World's End Blu-ray in full-HD to see how well the GPUs offload the grunt of the work from the CPU.
No real surprises, and all three solutions do a decent job with a mid-range CPU's usage hovering at roughly 20 per cent.

In our test system, Inno3D's GeForce GT 220 proved to be thirstier under load than either the Radeon HD 4650 or HD 4670. Is the use of more power reflected in higher temperatures?

There's very little in it, and readers should note that the Inno3D GeForce GT 220 was tested on a slightly warmer day, hence the closely-matched ambient-to-load difference.
What's unfortunate, however, is that the Inno3D card - which clocks down to 135MHz when idle and runs at a cool 35°C - remains loud at all times. The lack of a PWM-controlled fan is a major oversight, we reckon.
