1080p = 1920x1024 1080i=960x512
This being said 1080i still has to draw the entire resolution. The 1080p displays the entire image 60 times a second, the 1080i alternates displaying between each half of the image.
This is still rather confusing ....
You are halfway there. 1080p = 1920x1024. 1080i=1920x512.
At 1080p the framrate is 60 times a second. At 1080i the framerate is still technically 60 frames per second but it only displays 30 unique frames. For the display of 1080i it will show all the even lines of the frame and then all the odd lines of the frame. This means 1080p is more taxing on hardware because it needs to output 60 frames per second as opposed ot the 30 needed for 1080i. Hopefully this helps a little.
Also the PPC cores in the Xbox 360 are assumed to be simple in-order cores. See Anandtechs article on the cell CPU to get a description of the difference betweein and in-order core and and out of order core that AMD and Intel make. What this basically means is that the cores in the Xbox 360 will be great at some operations and complete crap at others. Another good read is the interview with Tim Sweeney at Anandtech where he talks about multithreading and the Unreal 3 engine.
I just love technology. It will be fun to see what this thing can do. And count me in the crowd who can't wait to hook this up the HDTV and Stereo and let it rip.
