AMD A10 5700 review -
Power Consumption and Temperatures
Power consumption wise, AMD was able to keep the TDP of these APUs on track, either 60W or 100W depending on your choice of APU. A higher power draw would result in unhappy customers, but obviously could also endanger heat levels.
The APU is a pretty clever product when it comes to its power design and power states. Not only can the processor cores independently be throttled down, lowering voltage and what not, there are different power states inside the APU allowing nearly complete shutdown of segments/domains within the APU. For example, if the GPU is not used, it can be powered or slowed down. The same goes for CPU cores.
We ran the AMD APU both with and without a dedicated graphics card. Without one (using the internal IGP) the PC idles at only 35 Watts, very respectable. When we place load on the CPU and we see the power draw rise the system now consumes roughly 108 Watts. This is with merely an SSD and 8GB memory installed. Your average PC will draw a little more power if you add optical drives, HDDs, soundcards etc.
It's a good chunk lower then a A10 5800 APU fot the sole reason that AMD shaved off 400 MHz on the baseclock and a little on voltages. That makes this A10 5700 a 65W TDP based APU.
When we put a dedicated graphics card into the PC (GeForce GTX 580) our IDLE power consumption immediately increases towards 69 Watts. And once we stress the CPU cores of the APU we get a 151 Watt power draw.
I want to make it very clear that power consumption measurements will differ per PC and setup. Your attached components use power but your motherboard can have additional ICs installed like audio controller, LUCID chips, network controllers, extra SATA controllers, extra USB controllers, and so on. These parts all consume power.
We review the 100 EUR AMD A10 6700 APU processor, the little brother of the 6800K we just reviewed a little while ago. Based on Piledriver architecture this processor slash graphics hybrid symbiosis called APU.

We review the 125 EUR AMD A10 6800K APU processor. Based on Piledriver architecture this processor slash graphics hybrid symbiosis called APU remains hard to beat in terms of features performance.
AMD A10 5700 review
We review the AMD A10 5700 APU processor. Based on the APU architecture and building on the strengths of the Llano design, the 2012 AMD A-Series platform has been updated to meet and exceed the increasing demands of today’s consumers.
