No.
The A7 is almost nothing like the A6. It has _double_ the number of transistors. In case it's not clear, that means that (if they were built on the same process size) the core would literally be twice as large as an A6. Each transistor is something that can fail - doubling the number definitely presents a large manufacturing challenge.
It is 64bit - which means much faster processing in floating point applications that use double precision (like iMovie and iPhoto). It will also be faster for non-floating point applications because of the increase in the number of registers on the chip.
It also has a much revamped instruction set - which will also provide performance gains once applications are recompiled to support it.
Finally, it has a MUCH faster GPU in it as well...
What exactly could they have done to the chip to make it a a significant change for you?
You know what -- don't bother. Some of us here are technologists, and enjoy learning how things work. It expands our minds, and if we play our cards right, can help us secure better careers for ourselves. And then there are the people who just want to argue and troll, and no amount of educating and explaining will help them, because they are not interested in learning about how things work (probably not capable).
