PS4 may in fact have Native Built in Hardware to Run PSVita Game's!

Wow, that's wrong. The ARM used in PS4 is compatible with other ARMs but it's compatible as a Pentium 1 was with Pentium 4, e.g., if you leave out the new instructions that P4 offered. The ISA (Instruction Set Architecture) is the same but not performace, so no, this won't happen.

no read it againL:

The Cortex-A5 processor provides full instruction and feature compatibility with the higher performance Cortex-A8, Cortex-A9, and Cortex-A15 processors - all the way down to the operating system level. The Cortex-A5 processor also maintains backwards application compatibility with Classic ARM processors including the ARM926EJ-S, ARM1176JZ-S, and ARM7TDMI®.

remember this is not about the x86 part its about the Arm cortex part, which you pointed out is not the same performance, but aaah we do not know what speed or how many cores does this A5 have?

Say IF is this is a

Ok, again: You say PS4 has an A5 in it, right? How many cores? Clocked with which frequency? Also the A9 used in Vita is, as you already said, has more performance *and* 4 cores. Compatible means just compatible, not "is able to run the same apps with the same performance". That's what I meant when using the comparison in x86-terms. The A9 doesn't have a better performance because of frequency but because of a better internal architecture/better pipeline/branch-prediction and so on - as every processor iteration evolves.

And obviously it would have to feature Vita's PowerVR-GPU ...
