So, the Rx480 has 2304 stream processors. According to the rumors, AMD's highest end Vega chip coming later this year has 4096 stream processors. Considering how impressive 480's performance is with 2304, imagine how impressive Vega will be with 4096. It might just dethrone the 1080, unless the 1080ti or a new Titan is out by then (October).

If Vega 10 or 11 don't outperform the GTX 1080, AMD is in deep trouble.

The 5TF RX 480 is 150W TDP.  I suspect power & heat will prevent a 6TF GPU console in 2017.

Before the official announcement Polaris 10 was heavily rumored to use just 110-135w of power. I get the feeling that AMD got a bit generous with their official TDP rating, I doubt it actually uses close to 150w, but I guess we'll see when the reviews start coming in later this month.

For what it's worth, the 7850 that PS4's GPU was based on was a 130w chip. 20w isn't that big of difference, MS would simply need a roomy case and a 120mm cooling fan, much like Xbox One's case and fan/heatsink. It's also worth noting that Xbox Scorpio may be using AMD's new 14nm Zen CPU architecture, so it's possible that MS could make up the difference with a lower thermal rating for the CPU part of the APU. At the very least I think MS will hit 5 tflops next year, maybe higher.

The RX 480 won't use 150W for a very simple reason: it only has a 6xpin power connector.

The card can only get 75W from that, plus another 75W from the PCIe connexion, and neither AMD nor Nvidia would launch a 150W card and feed it with just those 150W. Any small fluctuation or problem (from a not so good power supply, for example), and your game would crash.

So, if we assume a 5-10% margin, we have a 135-140W card.
