The graphics processing unit in iPad 2 has been identified as the PowerVR SGX543MP2, as step up in speed and performance from its previous version found in iPad 1 and iPhone 4.
Anadtech has run some benchmark tests for speed and performance of iPad 2 against the first-generation iPad and its most worthwhile competition, the Motorola Xoom.
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. There are also efficiency improvements as well. Hidden surface removal works at twice the rate in the 543MP2 as it did in the 535.
Apple claimed an improved 9x graphics speed with the new iPad 2 at the media event to announce the new tablet on March 2. Anadtech was not able to confirm that claim, but approached 7x speed in the various tests they performed with different games. In each graphics test, iPad 2 was much faster than the Xoom.
