Here, you can have them back....
SP's alone to not make a gpu. ROPs, TMUs, cache, memory interface, and any other logic also account for die space. Since we are talking ati cards here, lets add in UVD/HDMI functionality, etc...doubling SP's @ 50% die increase seems more than reasonable to me.
I mean really, how else is R770 different from R670?
What happened to your avvy with your old case in it
Anyhoo, they have also added 32 TMUs, and though your point is valid, 800 SPs is generally believed to be overkill unless SP efficiency is REALLY bad and they need to do it just to increase performance by significant amount.
As for your point about "what difference is there between 3870 and 4870 if they do that", take a look at the prices, they are almost identical to 3870 and 3850 prices at launch. If they really wanted to launch a 800 SP monster, they would have put the price similar to the GTX 260 at $449 and not $329 and $229. We have heard news that the reason for the low 4850 clock was because ATI does not want the 4850 to beat the 3870 by a large amount otherwise no one would buy the 3870 and that makes sense.
I just don't think ATI can put 800SPs on the same 55nm architecture as the 3800 series.
