No it does not. AMD own BS internal testing settings with 0xAF artifically boost Fiji cards up by a huge amount.\
Nano is for the ITX market what Titan X is for the gaming market(yes Titan cards are gaming and not gaming cards - usually whatever suits better). It offers 20-30% better performance compared to the competition (GTX 970 ITX) for a much higher price. 99 out of 100 people will not buy a Titan X or a Nano. But those cards target that 1 person that will consider it.
Remember the Fury X pre release benchmarks where they put it above 980Ti? That put it 20% above 980Ti in average? Most was with 0xAF.
Yeah that turned out to be 0% once real reviews came in.
Then its the Nano benchmarks. Looks like a true GTX 970 ITX killer right?
Also 0xAF and 0xMSAA.
That is on 4K. Which will maybe be +10% in reality.
We all know 4K is the Fiji`s strong suit. What happens in 1080p and 1440p? I expect 970 ITX and Nano to be very close.
Way different situation than Titan X +43% real performance over 290X (Click)
