The difference is that in 1080i only half the horizontal lines are drawn every frame. So at the 1920x1080 resolution of 1080i/p, 1080p draws 1920x1080 every 1/60th of a second and 1080i draws 1920x540 every 1/60th of a second. This even/odd rendering system allows 1080i to deliver the same temporal resolution as 1080p, but with half the horzontal resolution. It is incorrect to state that 1080i only runs at 30fps because the even and odd render fields can still contain separately rendered data from the game. 1080i and 1080p both run at 60 frames per second.
