Power, heat and noise

The fastest single-GPU card is also impressively frugal in terms of power. Evaluated as a system, it consumes fewer watts than a Radeon HD 7970 GHz Edition. We've demonstrated that TITAN doesn't have the wherewithal to properly challenge dual-GPU behemoths, but its performance-per-watt rating is beyond reproach.

Those who have read the architecture analysis will know that the GPU strives for a certain temperature target - 80°C being the default - so it's no surprise to see a figure close to this. All setups produce decent temperatures, it has to be said.

Relatively low power-draw and excellent engineering combine to offer best-in-class acoustics. The card really is quiet - you can barely hear it under load - and its noise profile is in stark contrast to the real din produced by the Radeon HD 7990 and two-board HD 7970s.
