Wheres your proof the iPad 2 is using the SGX543MP2? Oh wait I know! Its because thats assumption of the people because they are all figuring it uses the Orion which has the SGX543MP2.
Too freaking easy.
My assumption is based on the actual drivers for the SGX543 found in iOS 4.3 Beta, and the rumour which said it'd have the MP2. I can dig these up if necessary. Taking into account that Apple says it offers up to 9x the performance, it has to be at the very least the MP2.
Where's your proof it uses the Orion?
And, IF IT IS using the Orion and the Orion has the SGX543MP2 then IT IS more powerful than the Tegra 2's graphics.
