It seems that people think “Tegra” and all it’s marketing is the most powerful thing around. They use their marketing blitz to push the Tegra Zone with non-standard graphical tricks that make the games look better. People see this and think it’s due to the raw “horsepower” (or whatever term you prefer.)
Take the Tegra 3; people think it’s the best SoC around. You’ll hear stuff like “I don’t want the AT&T One X cause it’s only a stupid dual core.”
Wouldn’t it be nice to drop the dirty tricks and just make a very powerful chip in its own right? They seem to have no problem with desktop GPUs.
