High-end-Speeding dual core SGX543 graphics is moving onto iPad 2, iPhone 5

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. 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.

Apple TV has its own share of HDMI problems being reported by users, including handshaking problems that appear to affect nearly every Philips HDTV model and many Sony sets. Apple's existing A4 chip, used across all of its iOS products introduced in 2010 (iPad, iPhone 4, iPod touch fourth generation and Apple TV), pairs an ARM Cortex-A8 general purpose CPU core with an Imagination Technologies PowerVR 535 graphics and video processing core.

Samsung sells its own chip with an identical ARM core and a similar overall design, under the model number S5PC110A01, also known as "Hummingbird." Samsung used this chip in the Samsung Wave smartphone, which uses the company's own Bada OS, as well as the similar Galaxy S line of Android models, including a range of smartphones sold as Captivate by AT&T, Vibrant by T-Mobile, Epic 4G by Sprint, Fascinate and Continuum by Verizon and marketed as the Google-branded Nexus S. The chip is also used in Samsung's Galaxy Tab and the forthcoming Galaxy Player.
