Would a 660ti in a console be more powerful & efficient than a 660ti in a PC?

Console's GPUs are only based on desktop GPUs. PS3 has GPU based on nvidia 7800 G70 chip. But it is only based on that. They do their magic and boom...
RSX is much faster than 7800GT

what do you mean is much faster? the hardware is not, there is nothing special, just higher clock, but a 7800GTX have 256bit memory bus (RSX = 128bit DDR3) and twice the ROPs

the magic comes from how the software is made and optimized, compared to a PC.

now the Xbox 360 GPU is a different beast, it's 1 year older, but it's a custom design, with edram, and different shader architecture compared to the ATI cards from the period...

I would not overestimate the "programming direct to metal" aspect. I think that the biggest issue PC game programmers have is that every game that comes out must be usable on a HD 5450 512 MB at 768p and still be appealing on a GTX 690 at 1440p. This is a huge chasm in fillrate, memory size, memory bandwidth and shader power. On the console, even if the game creator doesn't program "to metal" and uses the APIs, they have a very specific target for all of these variables. For example, if Diablo III crashed to desktop if less than 1 GB of texture memory was present, Blizzard fans would be sad pandas - but this is not an issue for XBox users.

yes yes i think its just semantics: faster/more poweruful/more efficient, the point is a 660ti on a console can render more because of the software's efficiency and because of its more direct integration into the console's system. add to that some extra optimizations like edram, special software coding, and a 660ti can render the same scene with more FPS.

Granted, this is 3 years ago, but it shows that it isn't all about "to the metal" on the consoles either

Watch until at least 5 minutes.
