Whilst I hate Phil's marketing nonsense, the simple fact is that the x1x is simply a step above the ps4 in every aspect,
4k uhd bluray player
50% more GPU Tflops
50% more Ram quantity
50% more Ram Bandwidth
CPU is 10% faster and customised
In terms of 4k improvements on PS4P, I think it's fair to say that:
- It can play 4k UHD blurays
- It can have more 4k textures used more often
- is less reliant on checkerboard in etc, FM7 is native 4k 60 with 30% GPU resource left.
I know it's stretching the truth, but saying the ps4p is the same as an x1x is as wrong as saying the x1x is a generation ahead of the ps4p and the only true 4k system.
Depending on your viewpoint, to me the x1x is to the ps4p as the ps4p is to the ps4. Not a generational leap, but significant enough.
