Maybe a better thread than this is the XB1 doesn't need to use 3GB of memory for the UI/OS, regardless of whether it's GDDR3 or GDDR5.

Why doesn't it need to use 3GB for UI and OS? I like multitasking, preloaded games, insta resume, fast switching, pinning apps...

Because that's memory that could be used for higher res textures, larger drawing distances, game data, game engine, etc. etc. You know this. 

I am not sure what you expect from the Xbox 1 GPU/CPU, that is between 7770 and 7790, to do with more than 5 GB of ram in a single game.

I suggest running high end PC games on GPUs 2X more powerful than the one in Xbox 1 at 1080p and seeing how much total RAM is used for gaming once you subrtract Windows, antivirus and all that stuff... 

99% of the time less than 5 GB total RAM usage and GPU is always less than 2 GB...even with ubber high res textures.
