that is why i use the term, modified
they can bring the GPU clock speed down and bring the memories speed down... also, that power output is for the entire card, and here sony will only use the GPU, and mems, the rest could be taken down or rearranged in the motherboard...
they cut by half the power used by ps3 from the 1st fat to the 2nd slim... until then same things could be done to improve the power usage!
lots can happen until then!

They also cut down the chip sizes from 90 nm to 40 nm. You won't go from 180 to 100 just going from 28 nm to 22 nm. You also don't count the entire PCB board when calculating the TDP of a GPU...you count only the GPU. The rest of the board is minimal anyway.
Scoobes, the HD 7870 is a 180 watt GPU. Not going to happen.
As for downclocks to keep thermals in check. May was well use a different chip instead of a bulky HD 7970 or HD 7870. Why pay for silicon you don't need?

I was thinking something in between 7850-7870. From my understanding, the 7850 isn't a power hog but is still quite poweful. Maybe add in a couple of extra bits here and there depending on exactly what Sony and their devs are asking for. They may even cut out some of the features they don't need.

Drop some clocks on the HD 7850 and you might have a suitable GPU. Depends on whether they can get better performance from a smaller chip with higher clocks. Depends on silicon yeilds offer good pricing on chip sizes. Lots of factors come into play that tend to rule out bigger, faster, hotter chips.
