CPU - four Twister cores clocked >1.85GHz RAM - 4GB LPDDR4 GPU - ??? I will put my guess out there - the PowerVR GT7900 from Imagination. http://blog.imgtec.com/wp-content/uploads/2015/02/PowerVR-Series7XT-GPU.png http://blog.imgtec.com/powervr/powervr-gt7900-redefining-performance-efficiency It seems the only PowerVR GPU capable of powering the display with 80% more pixels than the Air 2 whilst simultaneously offering 2x the on-screen performance (as per Apple's official claims). All other iOS devices have utilised Imagination's GPUs (including the A9 powered 6S/6S+) so there is no reason to assume that the Pro will be any different. What are your predictions for the identity and performance of the GPU inside this beastly SOC?
