i have a 6s plus with a9 processor and graphics and play games like modern combat 5 and other fps on multi player and i wonder if i get a ipad for example with a9x processor or the not one to buy now Iphone 7 with a10 processor , can you see and feel the performance diffrence while playing or is it just numbers , and can the games perform more fps the better the processor and graphics are or is it limited by say 60 fps always or how does it work in ios and apps?
