They tried to streamline it with RDNA for gaming and CDNA
That's not streamlining, that's two different "clean" ways, they tried the two-way approach, after having a 1-way approach and now with UDNA (Unified DNA), they are going back to it. The two-way approach was to have better performance, and it worked, but made software-wise everything very complicated for them, that's why they're going back again.
and that's why Nvidia haven't supported Frame Generation on RTX 3000 cards.
No, FG isn't supported on RTX 30 because it doesn't have the optical flow analyser (a hardware part), that also is stronger on eg 4090 than on 4060, meaning, FG works better on 4090 than on 4060. I have scrutinised this heavily at the beginning of release of RTX 40 series btw until a friend linked me video of "hacked" FG on RTX 3090, which did not work well, since it doesn't have that hardware part. It worked "somewhat", which isn't good enough. A nvidia architect also explained this one time in twitter, and he seemed believable.
AMD failed with RDNA 3 not because of drivers, but because they failed to predict that a feature like RT, a gimmick that probably doesn't do much or maybe it does, would become a very important parameter
AMD failed with RDNA 3 because of a mix of things. Driver issues, enough to get people talking again about it, which isn't good, not huge ones albeit, RT performance mind share, being inferior there, not enough performance at the high end. Mediocre pricing (7600, 7900 XT until it was reduced). Then even things like FSR having a mediocre reputation, and too many people saying "DLSS is way better" (which isn't necessarily wrong, but also not the whole truth). All in all, a mindshare thing, at the end.
While I keep saying a number of things about Nvidia, the buyer of a $500 Nvidia card will only get gimped in VRAM
500$ Nvidia card gives you a 4060 Ti with 16 GB or a 4070 with 12, I wouldn't call that "gimped". You're gimped with the 400~$ 4060 Ti and that's it. The 4060 being a low end card, you will get what you pay for. And all other cards have normal amounts of vram, including the 4080. If someone was vram hungry he would get the 4090 anyway, guess why it was outselling so much. 2000$ isn't much money if you work with it, btw. The workstation GPUs are much more expensive.
lMAO. The 7900xtx is a midrange card compared to Nvidia. This will be lucky to compete with 5060
It has more shader than 7800 XT and better ones, the frequency is also higher, so I expect it will have at least 7900 GRE performance, which should be enough to compete in mid range. And with RT on it should have easily better performance than both, so, it could be a good card, but we will see. Again, pricing is probably more important than just performance. Price to performance > *
