Nvidia's compression is more advanced or was in the past I'm not sure how it compares with RNDA2 though AMD has made some improvements to compression compared to what it was like with VEGA. Both reads and writes are compressed now, but I have no idea what level of compression or what sort of algorithms AMD is utilizing for the compression itself or how they stack up side to side. Nvidia also has a lot of AA techniques that can save a lot on VRAM and performance DLSS, MFAA, FXAA, TXAA, transparency AA and so on. That held true with RNDA I don't know how much it holds true with RNDA2 that may have changed a fair amount hard to say.
It defiantly looks like Ampere's 4K performance is stronger than Ampere's 1440p performance in regard to RNDA2 which could also indicate RNDA2's 1080p as well as 720p is stronger in turn. I don't think many people will play at 720p at least on desktop, but on laptops that another matter and possible mobile perk in AMD's favor this generation to look for. I think it's pretty relevant to RTRT though because ray tracing performance certainly isn't 4K ready right now in a convincing enough way maybe in single player experiences with limited use of the tech itself which almost doesn't count. I think the RX6800 is the value winner this generation from what I've seen so far, but certainly want to see more conclusive testing and comparisons. The fact that it might potentially trade blows with the RTX 3080 at 1080p/720p while priced competitively with a RTX 3070 is amazing. We'll know more when in depth testing of the cards takes place shortly.
