(Numbers taken from Anandtech)

	HD 7970	HD 7900M
Stream Processors	2048	1280
Texture Units	128	80
ROPs	32	32
Core Clock	925MHz	850MHz
Memory Clock	1.375GHz (5.5GHz effective)	4.8GHz
Memory Bus Width	384-bit	256-bit
Memory	3GB GDDR5	2GB GDDR5

As you see, the cards are not exactly the same.

Forget GPUs with 384 bit paths instantly, even 256 bit paths is unlikely. Count the numbers of board layer any stable PC graphics card has - way too expensive for a console. As I have explained before, a (simplified) AMD7770 (which has a 128 bit bus) is cheap and more than powerful enough for 1080p/60Hz.

I was only comparing the 2 top of the line GPUs from AMD. the desktop and mobility ones.

I agree that there is no need for 384-bit GPUs in consoles, mainly because I don't think they will use GDDR5 memory but DDR3, and with DDR3 being slower it wouldn't be worth it.

And yes, an HD 7770 in a console would be powerful enough to play at 1080p (not sure at 60fps as developers always try to put more on screen rather than making it run faster). But the rumor we started discussing talked about a GTX570, and the 7770 don't reach that performance.
