Hmm, my memory failed me, I believed the HD7870 was weaker than the 6950, those are quite impressive, but I still wouldn't assume that Nintendo used any existing architecture, which is literally your fault
as I originally assumed that they would base it on an existing architect, but you persuaded me two or three threads ago that it would be a custom Nintendo design.
I think as to your high clocks vs higher clocks is nit picking, it means the same thing, as whatever i assume to be average clocks, higher clocks would be needed to reach high, I'm 27 and don't understand why I have to play games with words, it's virtually the same point. Nintendo choose to increase the clock speeds rather than add more muscle to the Gamecube GPU in order to create the Wii U chip, that is exactly what should point to them being able to come up with the idea of adding higher clocks to the Wii U than just adding to costs with something like 800sp shaders for the same effect.
As for the last part, you agree with the possibility of Nintendo being able to push the chip past 600mhz, but you assume they won't because they never have in the past, which I have just proved wrong...
At this point, you could be right about the chip, but it wouldn't be because what I'm saying is impossible, your estimations literally come down to "THIS F'ing COMPANY" lol (though I am paraphrasing, as you didn't say that, you only said that they wouldn't add more power that is easily available, because Nintendo doesn't like to do that.)
