All iPads iPad A7 Really A7X in Disguise?

Nope, it is A7 for iPhone 5s, iPad Mini and iPad Air. As Brian Klug said on Twitter last week. Slightly faster 1.40 Ghz processor and 115.2 GFlops GPU. 1 GB RAM and best factory calibrated screen ever tested.
What's interesting is that the A7 is even wider (issue width of 6 instructions!) than the ARM A15 or Qualcomm Krait. It's simply put the best ARM processor made yet.
Just read through AnandTech's review of the iPad Air to get a better understanding of the A7.
Came here to ask a similar question, because I've been thinking about the performance of these devices.
I sold my iPad 3 for the iPad mini Retina, and in the meantime I'm borrowing an iPad 2, and I remember when searching up benchmarks on these devices, although the iPad 3 has a better processor/graphics, the iPad 2 (And iPad mini) has better performance, evidently because of the lower resolution display.
So my question is, if the iPhone 5s and iPad Air/mini Retina all have the same processor, does this mean the 5s will perform better because it has a lower resolution display? There could be other things, perhaps the iPads will have a better motherboard and RAM, but if they're supposedly all using the 'A7' processor, that must mean the 5s is going to outperform the iPads, if we look at it simply.
Perhaps the iPads have got a better processor/graphics, but not 'good enough' to give it the 'X'.
We'll just have to wait and see, it would suck if the iPhone 5s does outperform.

its clocked slightly higher than the 5s...
When doing on screen GPU benchmarks like egypt HD it seems the iPhone 5S outperforms the iPad due to less pixels.

Nope, that's normalized at 300 Mhz. The G6430 in the A7 (iPad Air) is clocked much higher at around 450 Mhz.
Oh sorry, now I see
, thanks
PS
Is the g6430 in iPhone 5s clocked at 300 Mhz or lower?

Probably clocked at 1/4th the speed of the processor, e.g. 325 Mhz.
In most cases it is around 70% faster graphically, with some results a little less than 70% better and some a bit more than 70% better (maxed at 100% or 2x)
Not from what I saw, only some cases it was near 70% faster. It's still strange since Apple usually lowballs their improvement claims.
Apple wanted to use the same chip in all the new devices. That's cheaper than building a fast chip for the iPad and a slow chip for the iPhone 5s. There has been a review of the iPad Air on Anandtech, and the result is:
1. The chips are the same.
2. The iPad Air runs at 1.4 GHz, the iPhone 5s at 1.3 GHz.
3. If you make them work really hard so that temperature is a problem, the iPad Air goes down to 1.2 GHz, the iPhone 5s down to 0.9 GHz. Clearly the bigger iPad Air makes it easier to get rid of excessive heat. (Don't worry about this, Anandtech had to write their own software which was designed to run as hot as possible - no normal software is going to do that).
So all in all, the iPad will do more work per second, but the iPhone 5s with its smaller screen needs less work to be done. The graphics on the iPhone 5s is just much faster than needed. On the other hand, you realise that you can connect both iPad and iPhone to a TV and play games on the TV; in that case the number of pixels are the same for both and the iPad will be a bit faster.
I am a big fan of Brian Klug on twitter. Do you have any recommendations of similar people to follow who explain the technical stuff?
I agree, more like 40-50% but maybe in some cases. Marketing has never been truthful with most makers..
