TechSpot published AMD Radeon R9 Nano: Mini-ITX 4K gaming
A quote from the article:
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.AMD Radeon R9 Nano Review: Mini-ITX 4K gaming @ TechSpot
