Here's a list/infographic of all of the common resolutions out there: http://en.wikipedia.org/wiki/Display_resolution
The more pixels you have, the more power you need to draw an image on them, so generally 720p is faster than 16x12 is faster than 1080p given a constant system setup, and of course, image quality would go the other way.
