German Website PC Games Hardware also has made their Test: http://www.pcgameshardware.de/AMD-Radeon-Grafikkarte-255597/Tests/R9-Nano-Test-Review-1170704/
Apparently, in their test the Nano clocked around 910Mhz most of the time wile the card consumes less than 200W (so pretty close to the 175W TDP). Also, like most AMD Graphic cards, gains under DX12 are considerable, especially at higher resolutions.
