Steve Jobs said that the graphics performance on the iPad 2 was 9 times faster than on the iPad 1. That’s a bold claim, but recent testing by Anandtech confirms that the iPad 2 is a beast. The GPU powering the iPad 2 is the PowerVR SGX543MP2.
Architecturally the 543MP2 has more than twice the compute horsepower of the SGX 535 used in Apple’s A4. Each shader pipeline can execute twice the number of instructions per clock as the SGX 535, and then there are four times as many pipes in an SGX 543MP2 as there are in a 535.
Peep the results over here.
