I completely disagree with all the conclusions of this "article".
First of all, Nvidia's RTX is completely lacking support. A total failure. Hundreds of titles flamboyantly promised at launch have completely disappeared. Only a handful of games supported it, with debatable success and insane impact on performance. Thus, it's clear RTX can't be defined a feature at all. I would define it more like a flaw.
DLSS? 1? 2? 3? Whatever. A very pompous name for yet another upscaling and sharpening technology. Nothing to see here.
DLSS to help RTX? Oh, yes, why not? So RTX can achieve some decency in performance. Now, I wonder: what if only DLSS is used? Far better performance than have RTX activated. Once again, RTX is just a failure.
Wanna discuss prices? Ok. At current prices (and associated performance) the AMD's RX 5700 XT destroys the even more expensive RTX 2060 S and performs almost like the over 100$ more expensive RTX 2070 S and RTX 2080, making all of those three cards a mockery. The RX 5600 XT annihilates the GTX 1660 family of cards, no point of discussion here. The RX 5500 XT crushes the GTX 1650 Series, with only the RTX 1650 S putting up some kind of fight. But the 5500 can be found with 8GB, the 1650 is not so lucky.
Price/performance ratio? It's simply a slaughterhouse: Nvidia can't compete at all.
All in all, Nvidia has an edge over AMD only where AMD doesn't have any cards: in the 800$ and above price bracket. Everything else is just AMD superior value.
Thus the "just buy it" approach is just a plain scam for the users.
I only hope people can read this and think about it, before spending their hard-earned bucks. If they do! Because the next generation is getting close, and with gaming consoles performing like a 2000$ PC at a humiliating 400$ price everything is in discussion. Also, next AMD cards (which equip the new consoles) have all the features that Nvidia so miserably failed to implement in the PC gaming industry. The GPU market is on hold, currently.
"Just DON'T buy it", save money, and decide next year. If you must buy now, go AMD, hands down.
