It doesn't say 2W - it sez 2x performance.

“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. http://www.anandtech.com/show/7514/amd-2014-mobile-apu-update-beema-and-mull...
I'm not sure how this can be compared to ARM SoC power consumption, as they may use a different metric.
The entire EOMA68-A20 dual core with RAM and ethernet working is about 0.3A @ 5V or about 1.5W. A third less if its idling.
