The updated smaller A5 chip found in the the new Apple TV features significant power savings, according to an AnandTech report.

The power savings are nothing short of significant. The previous generation Apple TV wasn’t really a power hog, with platform power maxing out at around 1.6W, but the new model tops out at just a watt. Overall the power savings seem to be around 800mW across the board.

Since there is not a change to the process technology, it appears the reduction in power consumption is from other architectural or silicon optimizations.

Notably, since the Apple TV already used hardly any power there isn't much to be saved in costs.

Assuming you’re using the Apple TV for watching video 8 hours a day, every day of the year, you’d save about $0.26 per year on your power bill (assuming $0.11/kWh). You’d break even on the $99 cost of a new Apple TV in about 385 years.

'Me' may not care, but anyone with an iphone should. The Apple TV is a test bed for the chip being used in the iphone. A 1/3 reduction of power consumption, all other things staying the same, will make an 8-10 hour iphone battery last 10 to 13 hours. No, I wouldn't buy the new Apple TV for this reason, but the future iphone is looking good.
