Except the GK106 fully enabled with a 192 bit memory controller and all shaders is the GPU in the GTX660.

Considering the investment in these, there would be no reason to even suspect AMD will drop these.

They are using the Dresden fab to make the actually chips??

My point was that overall die size comparisons between parts with very different numbers of processors were not really comparable, in reply to someone who thought that because GK107 was much smaller than GM107 that any high-end GM GPU's would be unmanufacturable

GK106 - by a strange co-incidence - 0.23mm^2. As die size increases, the ratio of core:uncore changes. There's no magic. The transistor density is also fairly similar between the dies, if that was what you had in mind; they're still using the same node at the end of the day. (GM107 is slightly higher density, but it also has a higher ratio of cache on board, which is inherently higher density then core logic anyway)

Good point

I was being slightly ironic in a roundabout way with that line. My point wasn't that it makes the card hugely inefficient, merely that, as I said, people are making out how the efficiency is of such huge importance, then going out and buying a pre-OC card which adds little to performance, but reduces this "crucial" efficiency number...
Add another 26W, which is fairly negligible in real terms, and get a 265; a considerably faster and cheaper card. Considering the price difference at launch, we worked out it would take a few years of fairly heavy gaming use, and with UK electricity prices, for the 750Ti to work out cheaper in terms of TCO.

---

I won't pretend at all that the lower power usage has any part in the value of the card for the cards we're discussing, the only real benefit IMO for the lower power cards is less heat needs to be removed from your case (as in a ~20% reduction in the heat going through your GPU heatsink when comparing the 265 to the 750ti OC)

I should have made it clearer, when I mentioned performance I was comparing the GK107 650 vanilla to the cut-down GM107 750 vanilla (384 Vs 512 processors at about the same speed)
