News Ahead of Ampere, Nvidia Grows to 80% of Dedicated GPU Market, Analysts Report

Well, its not unexpected. AMD have not been focusing on GPU market lately. AMD is now putting their effort on Ryzen and Xbox/PS so I don't think we will see much from GPU front for now.

No doubt there has been mention about big navi for quite some time. Unfortunately, I don't think its going to challenge Ampere. More of just keeping pace with the changes in the market.
