Before bringing this article to a close, we'll take a look at power consumption of the AMD A6-3650 and some competing platforms. Throughout all of our benchmarking and testing, we monitored how much power this new APU was consuming with a power meter, versus other test systems we used for benchmarks in the previous pages. Our goal was to give you an idea as to how much power each configuration used while idling on the desktop and while under a heavy workload Keep in mind, this is total system power consumption being measured at the outlet and not the the individual CPUs or GPUs alone.

** The Phenom II X4 980 System Used A Radeon HD 6570 Discrete GPU

Power consumption, especially when idle, is a strong point for AMD's Llano, and the A6-3650 in particular. We saw idle power consumption of only 51W from the 3650 and peak power consumption of 144W (while taxing the CPU and GPU cores), which was right on par with the Intel Core i5-2500 based system.

With some lower-speed / lower-voltage system memory and a bit of CPU undervolting, it would be interesting to see how low a Llano system could go. Mid 40 Watt territory should be doable.
