In a rare first ahead of more official outlets, XBMC forum member aicjofs has posted a teardown of the newer 1080p-capable Apple TV that shows a number of changes. As suspected, it has upgraded from an A4 to an A5, although it's now using a slight variant on the iPad 2/iPhone 4S version with an APL2498 part number. Apple's media hub now has 512MB of RAM as well, which along with a second core should improve performance across the device, not just in the higher resolution video.
