The Ray-Tracing and AI hardware is a total waste of die space and money when it comes to gaming, even if its just $50. Most people will be better off putting that extra money towards RAM, SSD, their CPU, or even one of those little Optane modules. Literally half the hardware on the die generally won't be supported by devs for *years*, if ever. Just imagine how much better this generation would have been if that die space had been devoted to the actual GPU. Instead, the RTX line are just faulty quadro chips, so Nvidia is just doing the bare minimum amount of marketing to sell you on leftover features that are really only useful when companies like Disney and Google fill a warehouse with racks of Turing cards.
If Nvidia is still supporting these features in a generation or two, then maybe it's worth looking into (although Nvidia RARELY supports throw-away leftover enterprise features like these past the pre-launch sales pitch). At this point, I don't have much confidence that Ray-Tracing and AI hardware will even be supported within the same generation in a RTX 2060/2050. They have to cut out about 3/4 of the die to get costs down enough to compete with AMD's current options in the mainstream market. But, if they made that cut and continued to include the wasted hardware, then those chips would only be able to eke out about 75% the performance of the last-gen equivalents.
In the least, I think that it will at least be quite awhile before we see a RTX 2060 - because the reduced performance would force Nvidia to rebrand a would-be RTX 2060/2050 as an overpriced RTX 2030/2040.
Maybe they'll even have to split the product lines and introduce a graphics-only GTX 2060 or skip directly to a chip that can be cut into a GTX 2180/2170/2160/2150.
Bottom line, Nvidia has really marketed themselves into a corner trying to sucker people into all this this useless ray-tracing and AI crap. They're trying to justify a short-term (crypto influenced?) price-hike in a way that is ultimately going to do a lot of long-term harm to their branding.
