This speed boost applies not only to graphics, such as drawing polygons in a video game or rendering fonts in a productivity app, but video processing as well. The A4 includes hardware acceleration for video decoding and encoding, and both appear to be used to support high quality video conferencing in Apple's FaceTime on iPhone 4. FaceTime and a front facing camera did not make the cut in the original iPad, but are expected on the new iPad 2.Full details can be read over here.
Faster video processing could also enable Apple to upgrade the iPad and iPhone 4 from VGA-style component video output to the more modern HDMI, which is already used by the new iOS-based Apple TV. Some high end smartphones and tablet devices already support HDMI output, although not flawlessly.
