OP's comparison doesn't really matter since NX is DOA power wise if the rumors are true ...
That thing practically has no hope of ever surpassing current gen HD twins or getting parity within the X1 ...
Even the Pascal architecture won't save this thing from being slaughtered by 100+ watt devices performance wise cause that thing has to operate within a strict power budget ...
Personally speaking though I'm not all that interested about the compute power of the NX, what I'm more interested are in the hardware features like conservative rasterization or raster ordered views but I would've been way more interested if they went with Intel to see what they could do with that nice gfx IP providing that their advanced technology group was up to speed on the state of the art ...
