Yeah and they will once the product is out if it is any good.The difference being AMD are a bit irrelevant at the moment for many, they need to show that they're not.
They already showed us demo's back in January so you get an idea from that. If their driver team managed to eke out good amount of performance in 5-6 months, then expect minimum 1080 performance. Question is how will they price it and you know they would not let that slip until launch is imminent.
IMO they are better of under promising and over delivering then potentially caught doing the opposite. "Overclockers dream" comes to mind. They need to be careful.
