How about you wait for the actual promised launch date (May 27th) before calling it a paper launch? Otherwise we can say Polaris 10 was paper launched in March, they demonstrated working silicon and unveiled aspects of the architecture long before NVIDIA talked about gaming Pascal.
You heard it here folks. AMD beat Nvidia to launch months ago!
Except, back here in reality, AMD hasn't launched at all. We don't have specs, we don't have prices, we don't have reviews. They merely showed off the card. Or are you going to now say they launched it back in Jan @ CES when they showed it playing Battlefront?
Nvidia gave prices, gave out review copies but you can't buy it. That is the definition of a paper launch.
A paper launch is the situation in which a product is compared or tested against other products of the same kind, despite the fact that it is not available to the public at the time. Generally, the term is applied to the computer and gaming industry, but is not limited to that.

So you can either continue trying to say that AMD launched 6 months earlier than Nvidia, or accept that it is a Paper launch.
