Wait the iPhone 4s can handle it I'm sure the A5 not that far off from the A6 (like the A4 which is 7X slow at graphics than the A5 the A6 is only 2X better at graphics than the A5 its not a giant leap like the A4 vs A5 it is a leap in graphics power but I was hoping the A6 would of been like 6X or 7X faster than the A5 I think I will stay with an iPhone 4s in tell a quad core phone comes out by appl or maybe will get the iPhone 5 )
It's too late though. I've sold my 4s and will have the 5 next week. Luckily it's only a one year contract so can do same thing next year if quad core arrives.
Or just buy a new newer iPad (4) in march ish.
I am definitely curious to see what, or if there are any, differences between RR3 on a 4s and a 5. I can see that the quad cores on the gpu on a 5 will have a definite advantage along with the ram increase.
My only real concern was with the iPad 2 versus 3. But then again the gpu on the 3 is necessary to push for the retina screen. So other than retina I can't see there being too much difference between the effects on them.
Because its Real Racing, if there did turn out to be a big difference, I'd just have to get the iPad 3 rather than wait for the 4.
