12000 x 12000 = 1.44 * 10^8 pixels. 120 x 120 = 1.44 * 10^4 pixels. 4 orders of magnitude. And in addition to that, the RAW sensor information from the camera has given each pixel more 'depth'. Often times, each color is 12bit (36bit per pixel). There's more to each pixel than what's displayed on the screen: its not just a JPG you're viewing.
