First of all. I was not pitting it deliverately and second, I extended my argument with the inclusion of HD4890, the result is the same, and you decided to forgot about that little fact. How convenient, the HD4890 is not doing any better than if it had 512MB, but let's just forget about that and say the point is flawed.
Third the GTX285 doesn't need to run at 850 Mhz to be 40% faster than the HD4890, so that perf/transistor count is the same.
And finally, you are just trolling. My original claim is that we don't know the clocks of Fermi. If it is 600 Mhz like GT200, then it's twice the GT200, but if it runs at say 750 Mhz (still much less than 850Mhz) it will smoke the HD5870 big time.
In fact, I choose 2560x1600 in order to my claim NOT being flawed. ROPs make a card faster at higher resolutions and GT200 has twice as many. Where do all those extra transistors come from??? A LOT come from those extra ROPs, so we have to find a setting where both chips are using all their power, if we want to compare perf/transitors.
Anyway I'm done with the topic so don't bother replying.
Plz don't call people trolls based on that,
Since the GT300 is based on a totally new archtecture saying if its ???Mhz it will be faster than a HD5870 does not mean anything in reality because nobody knows exactly how that architecture will perform, for all we know it will be a bust, or maybe it will be the next step(which it will probably be) and in terms of saying rops give more performace at higher res, Rops instead of pixel rate are more tied to how fast the card can write the memory to the frame buffer and it changes depending on the memory bus they are connected to and since GDDR3 and GDDR5 don't have similar write clock and the 2 cards use different architectures comparing rops is iffy.
Do the Bulk of the Transistors come from rops, . . . . no(not much of the die at all is part of the rop domain), the bulk of the transistors are processing cores(IE, shaders.)
and from what I have seen having had a 9800GTX+ 512 and a GTS250 1GB, an extra 512mb can do wonders at high res but in the same right, ATI cards are better with higher resolutions with less memory(but more does always help) since the HD4K series so saying oh if the card were 1GB, it would perform better is not very right, a HD4870 with 1GB isn't going to perform much differently than a HD4870 with 512MB, why . . . look at most of the benchmarks on TPU and you will see why, its obvious that HD4K cards only need 512MB, any more than that dosen't give much of a boost and the reason you see the HD4890's being a good bit faster is because of their clocks, ben is right in my mind(Of course I only look at TPU info since this is TPU).
