same for iphone but this processor is inside the x _
But you're asking about replacing laptops with the iPad, the iPhone's use of the Bionic chip is immaterial because you're not looking to use the iPhone to replace a laptop.
As it stands for some people the current iPads can and do replace laptops, for many others, it cannot. The use of a faster chip (in my opinion) does not in any way alter the equation, so if the iPad Pro in 2017 cannot replace a laptop for your needs, then a new iPad Pro with the A11 Bionic will not either
