You won't use all calculations in FP16 like sergiodaly said. And although previous consoles could do it, the space and load on FP16 was equal to FP32, so what they have now is that in some situations they will be able to remove some of the calculations from FP32 and converte to FP16 so the 4.2TFlops will be used even more efficiantly than 1,8 TFlops of PS4 so the gains in GPU processing power is even more than a direct math calculation would show. But don't get the hopes too high before time.
