im sure the RT implementation will get better though, and even building a machine with a (relatively) cheap 2060 super is going to end up costing you twice what a series x costs, and eventually what the series x achieves graphically will outstrip the 2060 super at least. should really be more on par with a 2080 ti.
From what I've seen so far I'm really starting to doubt this, unless AMD figures out DLSS without the need for additional hardware but in the end Xbox Series X pretty much runs games at a certain 'PC setting'.
But I have a feeling Cerny is going to beat Microsoft in that race with DLSS and that's why Sony isn't using the RNDA 2.0 spec like Microsoft is but their own graphics API instead, they already had that checkerboarding thing pretty well implemented a few patents hinting at improvements of that
Where I think the Xbox Series X will pull ahead is VRAM. The 2070 Super, 3070 etc. are all stuck on 8GB of VRAM and that's not going to cut it for 4K down the line.
However, Xbox Series X doesn't hit native 4K in many new games yet either when ray tracing is involved so we'll have to see how that plays out.
