Will PS4 and X1 be maxed out sooner because their x86 architecture?

[freedquaker]

depends on what you mean "maxed out".

In terms of "unoptimized PC ports", yes, they are already maxed out in some ways (mostly GPU but not memory capacity or CPU).

But in terms of optimizations go, they are nowhere near as being maxed out. Neither of them will be maxed out before several years down the road. It will not be easier for PS4 to max due to relatively easier development but the bottlenecks in XB1, namely low memory bandwidth, missing rasterizers, simultaneously running virtual machines, reserved CPU/GPU cycles etc, will usually cause a performance differential in favor of PS4, more so than the compute units differential between the two machines.

Just remember that this console generation has unprecedented memory capacity, and it will take a VERY LONG TIME to entirely tap because it means a lot of work to fully utilize that capacity while most PCs don't have that kind of assets. This never happened before.
