Doesnt that mean it'll be half as fast? Overly-simplistic perhaps, but you get the idea.

Windows Mobile PDAs had a similar issue when they went from QVGA to VGA, though that only doubled the number of pixels but the gfx power stayed the same. The VGA PDAs were comparitively sluggish in anything graphics-intensive.

If you read the article carefully (it's not very clear on this), the new GPU core has 2x the performance of the old one. But it's a multi-core capable chip that scales fairly linearly, and apple are rumoured to be including 2 GPU cores. This would make it 4x faster, for 4x the pixel count, so existing apps will run at the same speed at the new resolution.

Kind of makes it easy for devs - not much work needed to use the new display, so long as your graphics can scale you can just tell it to run at full res and forget about it.
