If the GPU setups will be like this, then I think that while NVidia could certainly win out between the two at release, I fear that over time AMD will have the better legs and drop less in performance than NVidia.

Why you might ask? Well because the super-high-speed VRAM that NVidia is using is both rare and expensive, meaning that they will again put only the necessary amount for the time being and not enough for the future. Expect a 4070Ti with 10GB and a 4080 with 12GB VRAM.

This is already the limit right now: Doom Ethernal on Ultra Nightmare with Raytracing needs 9-10GB VRAM already. As such, any GPU with less Memory like, say, the 3070Ti, will get beaten by weaker GPUs with more VRAM, like, I don't know, a 3060? And even the AMD GPUs then are faster because the NVidia is too much bottlenecked: https://www.hardwaretimes.com/amds-radeon-rx-6800-and-the-rtx-3060-are-faster-than-rtx-3070-in-doom-eternal-w-ray-tracing-enabled/

As for Raphael, this was to be expected. I don't think they will change before Zen 5, where the rumour is that AMD will change to 12-CPU chiplets, which would mean 24 cores with 2 chiplets.

If this is true, then I expect AMD to build some monolithic hexacore for the lower-end GPUs, but like they're doing now for the Ryzen 3/Athlon/Sempron with Zen 3 in 12nm, just in that case probably with Zen 5 in 7nm or maybe 5nm (if Zen 5 is 3nm)

Well I am sure both companies will increase the Vram capacity next generation regardless so I doubt that will be the case. GDDR6X is expensive *right now* but memory chips get cheaper over time just like everything else. GDDR6 was also expensive at one point.

As for Doom Ethernal, Ultra Nightmare settings in texture quality has no visual difference than it's lower texture quality settings according to DF. Most likely, Ultra Nightmare texture quality is for resolutions well above 4k for it to really make a visual difference. So enabling a setting that makes no visual difference other than to eat up Vram doesn't make much sense and I highly doubt will be the norm in the future. There might be settings for higher resolution texture quality sure but you shouldn't be enabling say texture quality settings meant for 6k on a GPU meant for 1440p. Especially as things like Direct Storage and other next generation technologies start becoming integrated into engines that is supposed to lessen the Vram usage.

So I wouldn't say RDNA cards will age better as Ray Tracing continues to be implemented in more and more games.

I don't say AMD cards will necessarily age better, just that 8GiB VRAM is already too low for something of the performance class of a 3070 and especially the Ti version of the latter, and that NVidia probably won't increase the amount of VRAM very much next gen, resulting in the same problem happening again next gen.

I know Ultra Nightmare doesn't really change the look of the game, but it's an important benchmarking tool when you want to test the longevity of GPUs, and here the 8GiB GPUs simply fail.
