 roadmap document, page 4.

“Mullins ” APU
2-4 “Puma” CPU Cores
GCN Graphics Compute Units
AMD Security Processor
~2W SDP

For the ultra low power, APU they use SDP (Scenario Design Power), whereas for the other processors, they don't mention anything, so I'd guess they use TDP (Thermal Design Power).

Anandtech says SDP is ~2W, but TDP is 4.5W for AMD Mullins APU.

I'm not sure how this can be compared to ARM SoC power consumption, as they may use a different metric.
