The only indication received is a whirring noise of the fan at the time the Radeon starts especially under gaming modes.
the ratings achieved by MacBook Pro on the scoring of Geekbench and Xbench were 9,943 and 227.97. While this does not clearly nails the Apple claim of providing twice the speed of the existing processors, still, it does puts the MacBook Pro up from various other laptops in the market.
