Great review as always. Unfortunately from a consumer standpoint, the 6900XT is pointless. Let's play devil's advocate for a second and take AMD's word for it that the 6900XT is a 3090 killer. Looking at the performance summary page, the 3090 is only 5%/6%/8% faster (1080p/1440p/4K) but for a 33% price increase over the 6900XT. If you're dead set on getting the best AMD GPU you can and don't care about raytracing, then between only the top offerings from each company, the 6900XT seems like a pretty good deal. But unfortunately, the top offerings from each company don't exist in a vacuum. The 6900XT is 1% slower at 1080p and 1%/2% faster at 1440p/4K compared to the 3080, for a 30% price hike. It's 5%/5%/7% faster than the 6800XT, but for an even larger 35% price hike. There's no reason that I can fathom why you'd spend at $300 more over the cost of a 3080 for a 2% performance improvement at best.
It's great to see that AMD can make high end GPUs that perform in the same ballpark as Nvidia's high-end offerings. Nobody expected them to be as competitive as they are this generation, and they deserve the credit for that. The lackluster RT performance I can understand given it's their first go at it while Nvidia has had over a year to further optimize the tech. The biggest issue with this card is the fact that AMD tries to market it head to head with the 3090. Again, sure, at most it's 8% worse for 33% cheaper, but because the 6800XT/3080 are so close to it in performance, there's absolutely no reason to buy one. Now Nvidia will pop in with a 3080Ti that performs better and be able to price it at $999 because AMD set the bar there. Had the 6900XT been $750, a compelling argument could be made to buy one. I think that would be a fair price point. It just barely edges out the 3080 in 1440p and 4K performance, so between that and the greater amount of VRAM, a $50 price hike over the 3080 could be argued if you didn't care about RT.
Of course, all of this is a moot point anyway since it's almost impossible to buy a new silicon product these days.
TL;DR: AMD shot themselves in the foot with 6900XT pricing
