I don't get why there's such a big power difference.

Its simple really... That extra $100 is for Kinect which also takes up cpu/gpu resources

On top of that, ps4 is all gddr5 vs xbox one is ddr3 + small amount of edram... Gddr5 is faster than ddr3 but eDRAM is way faster than both however, the x1 only has a small amount of eDRAM to work with plus the developers have to use it properly to make it effective which is why the ps4 is overall faster... (I might be a little off somewhere though)

I also heard something about the cpu clock speeds being slightly different but yea, I believe those are the main reasons... MS isn't doing that bad considering it costs $100 more so far

The weakness of the X1 doesn't lie in the reserved resources or the slow RAM or the CPU. The main reason is still the fewer GPU compute units. The PS4 has 18 while the X1 only has 12. That's a whole bunch of graphical computing power more for PS4.

See for yourself: (2 cores on each are disabled for better yield)

 

And all thanks to the oh so great ESRAM that just takes too much space.
