Video
Apple’s new H6 ISP brings with it a modernization of the video recording options for the iPhone 5s. The default video record mode is still 1080p at 30 fps, but there’s also a new 720p 120 fps “slo-mo” mode as well. In the latter, video is captured at 120 fps but optionally played back at 30 fps in order to achieve a high speed camera/slow motion effect. The result is pretty cool:
In the camera UI you can select what portions of the video you want to play back at 30 fps and what portions you want to leave at full speed. The .mov file is stored on NAND as a ~27Mbps 720p120 without any customizations, however when you share it the entire video is transcoded into a 30 fps format which preserves the slow motion effect.
The slo-mo mode is separate from the standard video recording mode, it’s the next stop on the dial in the new iOS 7 camera app. Video preview in slo-mo mode also happens at 60 fps compared to 30 fps for the standard video record and still image capture modes.
Camera preview frame rate, toggling between slo-mo and normal modes
Adding high speed camera modes to smartphones is a great step in my opinion and a wonderful use of increases in ISP and SoC performance. I would like to see Apple expose a 1080p60 mode as well. Technically 1080p60 does require slightly more bandwidth than 720p120, but I’d hope that Apple targeted both in the design of H6 and simply chose to expose 720p120 as it’s an easier feature to market.
Standard 1080p30 recording is also available:

If that was the case why can moto x be made in america and still make a profit? clearly apple is just raping people.robbie rob - Monday, September 23, 2013 - link
I don't know where you're getting your info, but in the last year only TWO handset makers made a profit: Samsung and Apple. All others broke even or lost money. Broke even means made money, but by the time you pay everyone plus cost of manufacturing you didn't lose money - but you didn't bank any either.http://www.neowin.net/news/analysts-apple-and-sams...

the real probelm with these test is ios 7 has open gl 3.0 and android has it only on 4.3. most of these phones do not have android 4.3 infact i doubt that any of these phones tested had 4.3 when running it.for those who dont know open gl is OpenGL (Open Graphics Library) is a cross-language, multi-platform application programming interface (API) for rendering 2D and 3D computer graphics. The API is typically used to interact with a Graphics processing unit (GPU), to achieve hardware-accelerated rendering.

Well yes iOS supports oGL ES 3.0 but only the iPhone 5s's gpu supports itSo the Real "Problem" resides on iOS 7 and iDevices as well

NiceAs its all about apps - lol
it would be more interesting to see the performance gain there
as it will be many years before you see a native 64bit majority in the store.
even though the tests bode well for the future everyday usage it will be the
more generic apps that define its performance "today"

Section on A7 dual core vs quadcore design: you emphasized the A7's power efficiency advantage (lack of proper power gating on quad-core parts), as well as performance neutral factor - two cores at full speed is not slower than quad-core at so-so speed! A reference to the CPU section of MotoX review was made to back-up this point.Closer investigation of the MotoX review shows different picture: while performance can be comparable at best, the argument on power efficiency is so in favour of quad-core! It says running two cores at full high speed requires "ton of voltage", while running four core at 1.2GHz doesn't need that much power, hence more power efficiency.
In the end, do we have empirical evidence as to which design (two vs. four) saves more power?

Hmm! If this beauty is as good as it looks here, I'm afraid I won't even be considering the iPhone 5S! http://versus.com/en/sony-xperia-z1-mini-vs-apple-...Xperia Z1 Mini - same(ish) size, excellent features and hardware!
