Based on the fully fledged Fiji XT, the Radeon R9 Nano gets the same 4096 stream processors as the Fury X, just in a much more compact package. The Nano measures only 6" (152mm) long, which is made possible by the Fiji GPU's modest power consumption and HBM technology. AMD hopes to enable 4K gaming in tiny Mini-ITX systems with the Nano.
Compared to reference designs by Nvidia and AMD, their partners usually come up with creations that run cooler and quieter. A perfect example of this is Gainward's GTX 980 Ti "Golden Sample", with a 15% factory overclock that provides 11% more performance on average and a "Zero RPM fan design". Not wanting to simply just revisit the GTX 980 Ti's performance, we'll be hooking up two of these in SLI and test them agains a pair of AMD's Radeon R9 Fury X cards in Crossfire.
