Actually, the graphics processor (GPU) in the Droid 2 series is a PowerVR SGX530. The Bionic's PowerVR SGX540 has significantly more power.

The Bionic's display, however, is about as good as they come when reading outdoors in the sunlight. The very thing that makes it look "pixelated" also makes it much more glare resistant.
