I can't find the link to site where I picked up rumoured 720/PS4 rumoured specs (it was some German site), but it was more or less detailing diagram in following http://www.pcmag.com/article2/0,2817,2405922,00.asp, with some additional info, crunching numbers to equivalent of slightly overclocked 7850. Some other rumours for PS4 (http://www.vgleaks.com/world-exclusive-ps4-in-deep-first-specs/) are also putting it in this range, some even mention downclocked 7950 type performance. That's just few I came across in last few months, so either 7850 or 7970m (which is downclocked mobile 7870) could be decent starting points in lack of exact specs, considering they are around 8x (indicated next-gen projections) more powerfull than current-gen GPUs.

I have a hard time believing the PS4 and XBox 8 will feauture such powerful (and powerhungry) graphics cards. The diagram shows the XBox will use around 120 Watts total with the SOC around 50 Watts. That leaves less then 70 Watts for the GPU. A 7770 already uses 80 Watts of power.
And then there's the cost. Every rumor suggests the new XBox will be packaged with Kinect 2.0. I don't know what price Kinect 2.0 will be but I doubt it will be 50 dollars or less so unless Microsoft will release the XBox at a price range of 499 dollars (highly doubtful in the current market) or higher I doubt the new XBox will feature powerful and costly hardware like the 360 did at the time.
As for the link to the supposed PS4 specs, I don't believe them for a second. DirectX 11.5? The Tahiti supports 11.1, next up is DX12. A Graphics card of at least 399,- in retail? That's about the same price as the 7800 GT in which the RSX was based. If that rumor is true the PS4 will be the PS3 all over again. They could sell it for 499,- and still make a massive loss. Sony can't afford that.
And then there's the fact Sony has already said they wouldn't be gunning for the most powerful console next gen as that has only cost them money.
So I doubt the XBox and PS4 will use anything close to the tahiti cards. Even if they're underclocked a card based on those chips will require at least over a 100 Watts of power. That doesn't fit the diagrams 120 Watt of system power at all. An underclocked 7770 though (or an overclocked 7670 or equivalent) does fit the diagram. Those will still be more powerful than the rumored Wii U GPU though but nothing like 8 or 10 times more powerful.

I agree, Tahiti based card do seem bit of a stretch, especially considering it's tied to some of PS4 rumours, and knowing Sony's financial situation.....
On the other hand, 7850 equivalent card (or performance) does not sound that crazy - it's nowhere near high end card even at this moment (can be found for 180$ or even less), let alone one year from now, it's in the line of that 8x Xbox360 power performance target (not 8x WiiU, it's 10x e6760 in OpenCL fluid simulation and RayTracing), and if you look at 7970m (not saying they're actually using this one), which is downclocked mobile version of 7870, it's rated at 75W TDP - how they manage to do that compared to desktop version is beyond my knowledge to be honest. Add 95W Bulldozer 8-core CPU (not saying they're actually using this one)....still sounds reasonable I'd say (though not 120W as in that diagram) - original 360s were peaking around 185-190W in games, IIRC, PS3 even more.
