It may not be as big a surprise as the A4 itself was, but Apple has now confirmed via the latest iPad SDK Beta 3 documentation that the iPad does indeed use PowerVR SGX graphics hardware as part of its custom system-on-a-chip, which flatly contradicts previous reports of A4 using Mali, and lines up with what our pal Anand Shimpi has been telling us lately. What Apple doesn't confirm, unfortunately, is exactly which chip in the PowerVR SGX family the iPad uses, so it's still at least possible that it could pack a bigger punch than the iPhone or iPod touch.
