TP2 & TP1 Are The Same Spec Wise, Why Is The TP2 So Much Better?

[deadwrong03]

From what i've noticed and friends noticed the touch pro 2 is way better than the touch pro 1 even tho the specs are basically identical, i think the only thing different is the CPU Chipset that it uses if im not mistaken, but the Touch Flo (or sense ui in some tp2 cases) runs better than the touch flo did on the tp1

what makes the difference between the 2? the tp2 doesnt even lag anywhere near as much as the tp1 did. Does the newer touch flo on the tp2 use less memory or something? im just curious as to why the tp2 performs much better than the tp1
