Well, AFAIK, there have been three (majorly) different Xbox 360 dashboard designs/GUIs so far.
The first being the original one the console shipped with. The second being the NXE one which came with the fall 2008 update.
AFAIK those first two GUIs were only 720p native and upscaled at higher resolutions.
But there also has been a third majorly different Xbox 360 design/GUI. The Modern UI / Windows 8 tile like looking one which came with the fall 2011 update. The current one.
And i didn't know if this one finally is true native 1080p. So i came here to ask
.
But looks like it's still 720p only, which is kinda baffling
.
When the dash IS running, the OS has access to all RAM.
I just came across this (especially see the highlighted (bolded/underlined) part):

Did you know our system update package is only 7MB in size?
Or that the entire 360 O/S resides on a tiny 16MB filesystem and when running it is only given 32MB of system memory? I mention this as our developers and testers do an amazing job of coding for performance, and that is overlooked by a lot of people. Each day they are faced with adding more features, improving performance, and creating magical experiences with those hard-capped limits. And release over release they are able to pull off some magic to make it happen.

It's from 2007 though. So maybe that info is outdated?
PS:
Someone please rename the thread from:
"XBox Dashboard native resolution?"
to:
"Xbox 360 dashboard native resolution?"
I did not create the thread, so i can't change the thread title.
