iOS 4.3 beta contains Imagination SGX543 GPU driver

New code found within the first iOS 4.3 beta suggests Apple is planning to incorporate the POWERVR SGX543 GPU from Imagination Technologies into an upcoming product or products. Mac Rumors reports that the SGX543 is said to deliver seven million more polygons per second and double the fillrate of the older SGX535 that is found in Apple’s A4 chip. In addition, the new GPU offers support for the Apple-backed OpenCL specification, which allows applications to tap unused GPU processing power for general computing tasks, as well as support for multi-core configurations. Notably, a rumor from late 2009—the chip itself was announced that January—suggested that Sony was interested in using the chip as the graphics processor for its second-generation PSP handheld gaming console, suggesting that Apple and Sony are on a similar path when it comes to portable gaming.
