Ahh, an oversight - the Nano has an 8-pin PCI-E power connector rather than 6-pin. It can draw nearly just as much power as the Fury X in some scenarios. Good thing even with Powertune maxed out at 150%, the heatsink still did such an amazing job at keeping it cooler than GTX 980 Ti. So I'm shocked at how it beats the 390X overall, along with the 980 non-Ti, at stock settings. Either the Nano chips are truly cherry-picked silicon dies, or these Fury chips just hit a wall by design even with the watercooling setup on the X. It reminds me a lot of my old X1900XTX, when no matter the voltage or the cooling, it just hit a wall with only 50MHz overclock, while being even more power-hungry than my 8800GTX which was much bigger and faster.
It's interesting how the Hawaii and Fury cards have been running with so little headroom left, that the efficiency totally sucked, and then AMD catches us by surprise with the Nano. Just lose 10-15% of the performance, and gain 35% of power savings while in a much smaller form factor that does not require massive water cooling.
Still..... there's the damn coil whine as reported by Hardwarecanucks, Tomshardware, etc.. At $649, this is unacceptable, and defeats the purpose of a quiet ITX system. Perhaps AMD has a hard time "affording" the kind of QA for the VRMs/inductors... I wonder if AMD will ever get rid of the coil whine on their next-gen cards. Hardly ANYBODY is ever buying a Nano. So far, there's only 4 customer reviews over at Newegg.
