Relation to new iPhone screen sizes to Motorola Phones

Has anybody noticed that the iPhone 5 screen EXACTLY the same size as that of the Motorola Atrix 4g, though their resolution? Now that there is a rumored iPhone 6 with a 4.7 inch screen, I am willing to speculate that it will share it's screen size with the Moto X. The rumored dimensions of the device (though not the screen) could make this very possible.
