They are directly connected with one another and with 2 chip low-power 128MB DDR SDRAM. Since all these components are in the same chip, they can work faster while consuming less energy than before. The A4 requires less energy because its sub-components can be enabled or disabled as needed, reducing consumption whenever possible. 

The screen
The screen measures 3.5''and has a resolution of 960 × 640 pixels. Apple calls the Retina Display, and it has 4 times more pixels than the screen of the iPhone 3G. The screen has a resolution of 326 pixels per inch, a definition higher than a traditional magazine, a quality that is seen on the screenshots.

Apple claims that the IPS screen, the same technology used in the iPad has a contrast ratio of 800:1 which is 4 times better than 3G, with a larger viewing angle.
Applications will benefit from this resolution. They display text, images and vector graphics more accurate. However, developers should include bitmap images with higher resolution for their applications are beautiful to watch. 
As for the 3G iPhone and iPad, the screen has an oleophobic layer that makes it easier to clean.
