If im not terrible wrong , tensor cores doesnt do anything for RayTracing. If a 7nm RTX card can have more RT cores then yes it will be faster in RayTracing than 12nm Turing.
Right, though it looks like even if you had 4x the RT performance of 2080ti, you still would have nowhere near enough to run 4k/60 with more than a token effects presence ala BF4 (which already takes a whopping penalty even at 1440p). It's even enough to rule out the viability of Ultra settings @ Gysnc/Freesync 1440p/100hz+.
On the flip side, about 50% of an RTX 2080ti card is Tensor+RT. If it were the same size, but just double the traditional arch, it would have been a massive leap upwards.
I'm wondering whether or not RT will just crap out early, before coming back again later on, like some of the early VR hype did back in the day. It just doesn't seem viable with process tech slowing down so much, prices being too painful to be relevant to the mass market who is in the $100-$250 range, and looking at that kind of time it might take what, 8-10 years before a $300 card could do even 4K/30 raytracing in a useful manner?
The final nail in the coffin I believe will be that the PS5/Xbox Scarlett on RTG Navi (almost certainly already nearing final specout over the next 6-10 months so that manufacturing and supply contracts can be drawn up and committed to) have virtually zero chance of having anything more than the most token RT support, and more likely zero. Game development is incredibly expensive, and almost all the flagship level AAA stuff has to be developed to fit/optimize onto consoles. PC market is in much better shape than it was during 7th gen, but it's still not the driving force behind the kinds of titles like Assassin's Creed, COD, Madden, Fortnite, Far Cry, etc. So devs dedicating much time towards optimizing for something only a tiny fraction of even upper-range PC gamers can touch (and likely turn off due to performance not being good enough) .. it's a bridge too far I think.
I think Nvidia was very bold here, but I think this is looking like a failure.
