Thats not a dual GPU, its a variant of the M380. Which is a single GPU card, used in lots of laptops. Its a pretty decent mobile GPU.

no, its dual because i has the suffix "dx" behind it. Its not showing up on this site but really, its a dual graphic cpu which hybrid cross fire radeon r7 and r9 m380

For AMD, dual graphics is their way to using the APU and a discrete GPU together. A multi-GPU uses the x2 nomenclature. So this most likely goes into a laptop that uses an AMD APU, and has this on board as well. But that does not make this a dual GPU.

This.

Though you can be easily forgiven for the misunderstanding, since AMD doesn't even try to make it clear. Nor do they keep a good list of what's what: http://www.amd.com/en-us/innovations/software-technologies/dual-graphics#2

I'd suggest double-checking your sources. There likely isn't an official R9 385DX configuration; AMD's numbering hasn't gone that high previously.
