Does it have a Rogue GPU? 2X GPU is only a bit faster than Galaxy S4. If not, why Rogue comes so slow into market?????

That's great news
Faster than most would have thought...
Twice as fast, half of it due to the CPU(s) ?
Oops...
2 x CPU speed, 2 x GPU speed compared to A6 in iPhone 5.

That's certainly not what we've seen with x86.
Furthermore, anand seems to disagree with you:
anandtech said:
What do you mean? Performance-oriented applications benefit from the architectural changes.
x264 is ~10% faster in 64 bit. I believe the same applies to Cinebench, but I've no personal experience with that.

And how is 10% "a lot more"?
The dropped the "this is SLR level" comment about the camera. Yay for trying to be taken seriously.
Larger pixels (1.5um), which is cool. Still no OIS, which is less cool.
Fingerprint sensor, now.

Now that is cool, looking at how they assembled it into the home button ;-)
Think Apple should step up on the camera. Agreed that the mega pixel race in smart phones is BS, but
then go for a really large sensor or take the Nokia approach where binning is used to maximize SNR ->
better low light. You can achieve only so much with trickery (think he mentioned auto-tone curve blah blah).
For single thread performance, 10% is quite a lot, especially considering that's just from an architectural change.
Further, 64 bits is not just about 4GB RAM. For example, current iOS is only able to do memory mapped file up to about 700MB. A 64 bits system will be able to do much larger memory mapped file.
There are also other smaller benefits, such as larger space for tagged pointers.
Look at the number of LTE bands the 5s/5c supports

It looks like TD-LTE for China Mobile is there.

I've really enjoyed the series, and this looks like more fun. I'm not too impressed by the graphics upgrade from what I can see so far, though.

Apple has made architectural transitions many times in the past. It's a good idea not to wait until you're squeezed up against the wall. Personally, I think it's as simple as that. They've had access to the ISA, it offers immediate advantages, and they are early out of the gate in making the transition. Advantages all around.

Except this 10% comes from a very specific task (decoding x264) and it's not an enhancement that presents itself across the board.
When the first 64bit CPUs started to appear, I remember seeing how all those new 64bit made specifically for the new processors would bring little more than 3-5% performance improvements, if at all.
The 64bit implementation seems to be more developer oriented than a performance/efficiency-enhancing measure.
I'd bet most of the performance delta between A6 and A7 comes from the A7 allowing for much higher clocks, even if it's in burst periods.

The most I can find from any current model is the S4 which is a hexaband LTE model.
Does this mean the 5C has RF360 inside? How else would they be supporting 13 LTE bands?

Apple specifically pointed out the 2x increase in registers which seems like a very technical term for the general media. Did previous ARM CPUs really experience that much register pressure to make the register increase noteworthy or did they simply point it out because 2x sounds impressive?
I think that's more to do with the fact that x64 Windows was not very popular until Windows 7. On the other hand, Apple chose to make iOS 7 64 bits from start, and that's good for people optimizing for 64 bits.
