Megapixels are overrated,galaxy nexus can take better pictures than s3(5 vs 8),look at Nokia pure view 808,41 megapixel but does it make any differences between smart phones camera?

htc one really got me excited, been following its news every day...
just went tru the xda HTC ONE mega info thread
http://forum.xda-developers.com/showthread.php?t=2157153

found out about a few things

first, about the camera
ONE seems to capture at faster shutter speeds vs 920 at lower shutter speeds
so 920 results will be brighter, but then there will be motion blur (ie engadget comparison 2nd set, singer on stage)
also, using the oneX as comparison, oneX camera seems to capture same detail as iP5, as using the "auto correct" function in the Sense gallery will get almost the same result as iP5 straight-out-of-camera results, meaning that iP5 applies correction straight away whereas HTC you have to do it manually...
these are all results after researching done by a member on the XDA thread
and, since we have reason to believe HTC ONE camera will be better than oneX, I personally am optimistic about the camera performance

2nd, there are reports of HTC ONE using ddr2 ram instead of ddr3 ram for the GPU, causing about 30% performance reduction compare to other S600+ddr3 GPU.... but then some also say that HTC ONE has ddr3 GPU...
I would really like to get a confirmation on this, anyone has source? not that the 30% performance reduction is gonna make me go for other phones, S600 is still plenty fast & ONE still a phone i lust for... but knowing that we have the best of the best always feels good, no?
