We have all the clarifications we need. So far, reviews show that all the AMD RX480 cards draw around 160W. This settles the question how fast the Sony SoC will be. Even the rumoured/leaked 911MHz gpu clock probably is at the high end of what goes. |
AMD has stated that the power draw of the Radeon RX 480 is not as it was designed and will be rolling out updates to rectify it.
Also keep in mind that comparing a discreet GPU to a SoC/APU is like apples to oranges, ESPECIALLY in regards to power consumption.

Er. The reason why the Nano managed to get a much lower TDP was because AMD took the fury Chip... And tested them all, all the chips which hit the lowest voltages was reserved for the Nano cards. The chips which didn't, were sold as Fury.
Voltage has a direct relationship to power consumption in processors.
Consoles don't have that luxury, they cannot take a chip and scale it's clocks and/or voltages and sell them off to different market segments, they need to be conservative and try to get as many usable chips at a certain clock as they can to keep costs low (Consoles are cost sensative remember!)
Which means voltages are likely to be conservative and thus relatively high, which impacts TDP.
They can get around that somewhat due to consolidation... There aren't multiple memory controllers, power delivery systems, memory pools, you name it.
