Sorry if this is stupid, but not being a gamer I'm having trouble understanding the following: GPU power equates to running a high resolution game at high frame rates (right?) So if the iPad can run Infinity Blade Dungeons at native resolution at usable fps, that makes it a pretty beefy gpu, even by desktop standards right? I mean people were complaining that the GPU in the 27'' iMac was not powerful enough to drive its huge display at proper fps! And if so, why can it be so much better with so little power usage? I mean its not like the ARM vs Intel debate where ARM 'seems' faster and cooler because its outputting to the iPad, in this case both are drawing pixels, which should be the same on an iPad or iMac. Any knowledgeable input is appreciated.
