Apparently, Nvidias only answer to this is to include their Reflex low latency tech to lower latency in the first place. Which is fine, but does nothing to help movement control with low game-engine-fps.

3070Ti is a 256 bit 19Gbps G6X card with 608GB/s of bandwidth.
4080/12 will be a 192 bit 21Gbps G6X card with 504GB/s of bandwidth.
That is a regression but not "less than half" for a 40TF card.
Still there will certainly be some cases where the big L2 won't help - we've seen this on RDNA2 already.
22.5Gbps will be used on 4080/16 only AFAIK.
Relfex is a part of DLSS3 for a reason, they may do something with input through that.
But I suspect that frame generation feature will work "well" only when your "native" framerate is above 60.
It's not starting to sound like it. That's essentially what it is. It's derided in tvs because the quality is poor and it drastically alters the feel of a movie. In games we want higher fps, not less.
We'll have to see how the implementation is in practice but in theory I see it as a the opposite in that frame multiplication is primarily aimed at high refresh and solves (or at least greatly mitigates) the issue of the rest of the system (if not the game itself inherently) being limitations in driving high frame rates regardless of the GPU's capabilities. Being primairly aimed at high refresh applications itself would also essentially mitigate latency issues.
120fps+ (including taking advantage of 240hz or higher displays) would actually be doable outside of esports titles. Where this will ultimately lead to (if it can further scaled up) is in combination with OLED (or equivalent) or at least fast enough LCD displays that are at 480hz (or higher) allow for essentially near perfect motion quality without relying on strobing/BFI (which have their own issues).
Video frame do not have motion vectors in them.
Btw I wonder how much of an impact mining had on Lovelace memory subsystem design.
Narrower buses with bigger caches seem like a fine way to fight mining hash rates.
Alas doesn't look like this was needed.
I'd doubt it, there's other ways to tackle that if they wanted to. I actually wonder if there is any hashing limitations. Also the designs would've likely had to have been very far along already before the start of 2021.
The memory design just seems dictated by the what's available. There's no way to increase actual raw bandwidth without going to HBM. GDDR7 or whatever next gen memory technology isn't here yet.
They could have used wider buses on 104 and 103 chips.
Don't they have some big L3 'Infinity Cache' now too? I remember this from rumors, at least.
Bit more thinking how bad the 4080 12GB looks in the stack. The SM ratio between the cut down AD102, 128 SM 4090 and AD104, 60 SM 4080 12GB is absolutely wild, 46.9% rounded up. Previous gens for perspective:
3090 82SM -> 38.4, 3060 Ti has 38
2080Ti 68SM -> 31.9, 2060 has 30, 2060S 34
1080Ti 28SM -> 13.1, 1060 6GB has 10, 1070 15
980Ti 22SM -> 10.3, 960 has 8, 970 13
So saying it should be a 4070 is actually generous, it's more like a 4060 Ti compared to every other gen's ratio which is partially re-affirmed by the 192 bit bus. The 4070 is probably going to be 52 or maybe 54 if they have a 4070 Ti, which would make the 4070 more like an x60 non-Ti vs x80Ti/x90 in previous gens purely by ratio. Yes AD102 is a big leap over GA102 but you could park a bus in that gap. Business wants money etc but $900 for a 4080 12GB which by their own slides is slower than a 3090Ti in raster, making it maybe 15-20% faster than a 3080 for 30%/$200 more 2 years later? Take a bow 104, you have peaked
Also confused with their "191 RT Tflops" claim for the 4090 (and the "200 RT Tflops" they gave in the presentation). 2.52GHz * 512 tensor FP16 ops per SM/clock * 128 SM = 165 "RT Tflops", for some reason there's a 15-20% modifier applied. They said SER was a "up to 2-3x increase in RT and 25% in overall game performance" so that's not it either

I'm much more worried about the artifacts. Here's 4 frame sequence from Digital Foundrys (NV controller) preview
Yes.
I want ML motion blur as well.
Once we have upscaling, frame interpoaltion and motion blur, i would start to agree with saying tensor cores are worth it.
Yeah, it's good that more would pick up tech to lower input latency. There's some games with amazingly bad input lag.
However, it's something that really has to be felt and experienced first hand as so much of this varies by person. It would be ideal if there were kiosks at local stores so one can try it in different games, but that is a huge ask. The closest we'll probably get is a handful to a dozen different reviewers giving their hands-on writeups.

That's what I'm in interested in the most, how does it feel rather how does it look.
Ugh, that's bad. Halucination stroboscope expected.
They still have some work to do.
My proposal: Interpolate all frames, to get rid of the stroboscpe. Though, twice the cost for twice the soup. <:/
