The iPad Air and iPhone 5S GPU measures out around 150 gflops, the Wii U is rumoured to be around 350 gflops (possibly more), the PS4 can peak around 1,84 tflops or 1840 gflops, while the tablets and smartphones make leaps in technology, I'd say give them 3 years to match the Wii U's graphics performance, by the time the tablets and smartphone's reach the PS4, we'll probably be well in the 9th gen. Don't forget dedicated GPU and CPU technology make leaps too (Nintendo's rumoured Fusion console was rumoured to have a GPU performance of 4,6 tflops or 4600 gflops)
