Nvidia had some competetion back then. Now they have no real competetion at all. Vega was a major flop and Polaris is no longer competitive. It would really surprise me if Nvidia decide to make another big leap in terms of GPU performance.
Probably not gonna happen. RTG offers little competetion. I would be surprised if 1180 matches 1080Ti performance. 1170 would probably just be at 1080 level.
Only advantage of 1170 over 1080Ti would be hardware accelerated ray tracing tech IMO
The departure of Raja is probably one of the best things happened to RTG in a long time. Now they at least will be lead by a competent leader Dr. Su.
RTG ain’t gonna die. They may just focus on consoles and industry solutions.
MCM in theory sounds nice, just like many of RTG's promises that were supposed to "revolutionize gaming" while in end never picks up any steam.
IMO RTG will probably just stay in the mid~low end performance range in the next 4~5 years. They bet a lot on the ditection of GPU accelerated...
