Wccf tech did a test of 5700XT vs 2060S with them both o/c:
The result was basically a tie as 2060S o/c's so much better, so in reality it's not actually much cheaper then the equivalently performing Nvidia card, but lacks the features (which is not just RT/DLSS but things like variable shading, VR support, GSYNC, etc).
This is the descrete figure:

AMD is making a lot of sales of cheap 570/580's which is not surprising as they are a bargain.
No one should EVER use WCFtech as a source or info or reference for anything, it's a useless gossip site, worse than the celeb gossip ones.
Nothing they write or do there should be taken serious, it's not a serious website, it's a gossip blog. So I wouldn't trust a thing coming off of that cess pit.
Do you really still consider RT which is pretty much for DLSS as a feature? Literally a simple sharpening filter is 10x times better than Nvidia's limited DLSS. Its limited to certain games, at certain resolutions and certain settings and even then it works bad. I'm sorry but Nvidia's own new sharpen filter does a much better job than their DLSS.
variable shading is already supported by AMD and has been since Vega, they just don't call it that. Plus if you want to drop names Nvidia still doesn't support cache memory, rapid packed math, radeon chill, etc...
VR support? What are you smoking? All VR games work on all amd cards, its a niche market with less than 10 million VR units sold, and that is a number of how many are on shelfs, not really representative how many people have bought them and it's now been over 3 years since we've had VR tech. Again VR games work on amd as they do on nvidia. performance depends on game engine, unfortunately most use unreal engine which has always favored nvidia by a lot. Its an old engine, it uses old techniques for rendering, it doesn't support vulkan or DX12, it doesn't utilize a lot of processor cores, its limited in scope, but its easy and accessible, that is why its mostly used by small 3-4 people team who create small indie games.
Gsync is a sync technology, it has nothing to do with monitor feature specification, though yeah Nvidia did pay monitor manufacturers to create amazing spec monitors with gsync, but they also cost an arm and a limb, the starting point for these monitors is $1000, an unrealistic, overpriced hardware demo.
