Very Debatable, G7x has had quite a useful lifetime and offers great performance acorss the spectrum.
ATI's has some edge in the image quality department, but nothing too dramatic.
OpenEXR HDR FP16 with MSAA, and Angle Independent AF, are the two things that stand out and in exchange for these 2 features, ATI made it's GPU's much more costly to make as well as significantly higher power consumption.
Those two things should easily be fixed with G80, Nvidia had Angle Independent AF prior to NV40, and the Open EXR + MSAA should be a given for next generation.
I do agree that the 7 series has had a productive lifespan. However, I do have to give ATI some major credit for some of their offerings, even though they were delayed. They have made some of the biggest transistions in between card launches. Heck, even the upcoming X1950's are going to have a completely different GDDR than the previous version. They could have just shrunk the die between the X1800's and X1900's and then merged two X1900's together and claimed it was one X1950. Both camps have contributed a good amount of technology, Nvidia with their GPU multiplications and ATI with their GPU/Mem interactions and IQ offerings. I've enjoyed both over the course of DX9 so far and am hoping that they continue to do different things.
Well judging from what I have heard of the X1950 Series, only the top model will be equipped with GDDR4, the Pro will be souped up X1900 GT with the Crossfire functionality on the die itself as well as higher clocks on the memory and GPU.
Shrinking the die of the R580 to 80nm wouldn't have done much good as it would still be 280mm2 which is about the level of the old R520.
The way they did it, is just implement increased memory bandwidth and that was basically it, that requires changing the PCB some, but the die functionality remains the same, the ring bus memory controller already support GDDR4.
It makes sense since R600 is a tad further off in the distance. They wanted a little something to bridge the gap.
Nvidia doesn't want to refresh again with NV4x/G7x based technology, they will skip to G80.
Yeah I do enjoy the competition between the two, as it provides me with choice and that is always a good thing.
