Again, nothing but typical forum over-reaction. There is massive inertia in the market, many people just keep buying what they have always bought.
It really takes continuous, superior execution over time to really move the market, and/or a competitor that repeatedly shoots itself in the foot. Unfortunately for AMD, they are on the wrong side of both of those markers.
Back before the Mining craze when RX-480 vs GTX-1060 were selling as gaming cards. AMD had slightly better perf/dollar, yet IIRC NVidia outsold them something like 10:1. Check Steam HW Survey. 14.9% of the entire Steam User base in running a GTX 1060, and 0.3% is running an RX 480. That is 50 Times more GTX 1060s! vs the "competitive" RX 480.
Check Ryzen, AMDs first competitive CPU in a decade, with big core count advantage over Intel. Check Steam HW survey, during the whole year since Ryzens release, AMDs CPU market share had a continuous gentle decline. Mindshare and inertia at work.
NVidia has a massive mindshare advantage that won't be overcome by AMD finally having a competitive product.
The assumption that a couple of products swing the market is simply wrong.
