FWIW Wikipedia claims that GB202 is 92 billion transistors - which makes it 21% more than AD102 for a 22% bigger die.

How about you if the lag is still there? Will you still believe the salesman despite the evidence, and struggle to come up with a new theory of why it lags just like it's doing interpolation, while believe it's not interpolating?
Hey maybe the fake frames don't identify as interpolated frames. Maybe they think they are real frames, just like their buddies.

Nvidia didn't say anything about FG latency being reduced, at any point, at least I don't remember it, I think they said it improved fps for x2.
If latency improved, they would say it out loud.

And I'm sure that's true, just like the 5070 matching the 4090.
Still hung up on raster perf? It has been dead for a while. Can't play any game today on RTX 40 series without DLSS 3.5. In general, turning off RT/DLSS/FSR/XeSS in recent games leads to poor visuals, poor performance and poor gameplay.

And yes, 5070 matching 4090 is true in that context. A 5070 with DLSS4 FG (1+3) can catch up with a 4090 with DLSS3 FG (1+1) in FPS (although, compared to a 4090, a 5070 may have other issues).

5090 has better raster than 4090. That itself should make a difference in FG latency.

I like the look of the new MSI 5090 cards. It seems they have both 2 and 3 fan AIOs now. AIO is much more worthwhile for the GPU than CPU (not just the temps, but exhausing all that heat out of the case and making the card itself much smaller) and I think they should be more common.

I bet street price will be at least $2500 on any of these though, with sporadic Microcenter drops or scalpers the only way to get one. I got my 4090 from a scalper but at msrp+tax price. Not keen on 575W power usage either. The 4090 usually tops out around 420W even in RT games.

If you leave aside the DLSS, the performance gain seems like 30-40% which is less than they were saying before. That is like 1080ti to 2080ti which was not worth upgrading to. Maybe it's more in RT path tracing? That is the only thing 4090 struggles on.

DLSS 4 FG is claimed to be more efficient, slightly faster, and use slightly less memory. I didn't see anything about latency either.

The testing I saw for DLSS 3 FG, show added latency almost exactly equal to 1 frame time, so they already do a good job of not adding any extra latency beyond the time to buffer one frame.

There is no real way to reduce latency unless they actual stop buffering a frame.

So, it will be pretty easy to tell.

Given what DF has said, I expect, 2X added latency will equal to frame time ( the same as DLSS 3 FG), 3x will equal that plus some additional fraction of that, and 4x will add an additional fractional amount.

Here is where DF discusses DLSS 4 latency:

I dont get why they are going after more fake frames....
They should be spending time building NVidia Game Assistant.

NGA plays the games for you to max out yours levels and gear without all the tedious grinding, so when you do have time to play you can go straight to having fun!

Getting off topic but it would actually be cool to have neural network imagined parts of the game so everyone can have a unique experience or something like that. That would be cool.

Gaming reimagined - personalized games to suit what you like.

Like oh you have GTA but you get a personalized city.

What?

You know 5070 only has a *chance* of being 4090 when you have fake frames into the equation right? Nothing to do with DLSS. That's still dependent on "raster performance" which you think is unimportant.

Maybe someday either AMD or Intel will say "Enough!" and get a card that focuses purely on raster over x8 or x16 fake frames.

unless this AI craze ends that’s not happening. Looking at AMDs CES pathetic keynote further proves my point

looks like you need to work with their "Slang" shader language, so you're going to need to maintain two totally different implementations of all your shaders.
Slang is now openly governed by the Khronos Group.

Slang empowers real-time graphics developers with innovative features that complement existing shading languages, including modular code development, portable deployment to multiple target APIs, and neural computation in graphics shaders. Hosting under multi-company governance at Khronos will enable and foster industry-wide collaboration to drive Slang’s continued evolution.

Bit too late for that buddy, this is what AMD has to say on the matter, and looking at financials, can't really rebut that...
Improving performance in the areas that gamers care about most - ray tracing, ML Ops for FSR4 and ML Super Resolution

This guys seems trying analyze DF C2077 video. There more posts
I mean all I'm getting from that thread is that DLSS4 isn't artifact free, but it's still superior to DLSS 3 in pretty visible ways. I don't get why he's crapping on it so hard though as a general product. Isn't DLSS4 and even DLSS3 good enough for most people, like personally I can't spot 99% of the artifacts in the DF video even with video speed at 50%. I don't even usually notice much difference between FSR3 quality and native at 1440p, and according to most reviewers DLSS3 is superior to FSR3 and DLSS4 is so far shaping up to be another improvement. I don't exactly have the sharpest eyesight/perception but neither do many consumers so I don't get the outrage here with upscaling artifacts. Upscaling isn't "free frames" but it's significantly better frames at a nonequal lesser image quality. Not sold on MFG/FG but upscaling is definitely useful for consumers.

Also don't really get the Dune III, thing here. One scenario is a movie full of CGI pre-rendered on million dollar clustered-computing systems, and the other is a real-time game played on your 1k-2k pc, even the "highest end graphics" for consumers is nowhere near a hundred million dollar movie's CGI. I get that an ideal scenario would have zero upscaling but in the real world where we oftentimes don't have enough raw raster/compute, upscaling is a benefit to customers not a detriment. Obviously Nvidia is upselling their technology, and the claims like a 5070 provides a 4090 experience are absolutely ridiculous, but it's no reason to be all doom and gloom.

AFAIK, the hardware for upscaling thus far hasn't been exorbitant on die space and therefore has provided more benefit to the gaming experience than an equal amount of die space allocated to more traditional GPU hardware instead. The only concern I have with the adoption of upscaling technology is that game developers make it the norm for playable framerates, this goes double for FG/MFG.

The thing about AI that concerns me is the fact that while we can code the neural net and train it, at the end of the day we don't know how it is doing what it is doing. I'll give you an example. It has always been impossible to remove a stem from a mixed song. A stem is just a track, like the vocal or bass track. Over the years we've used EQ to accentuate part of the audio spectrum, or use phase inversion to cancel out signals panned straight up the middle, but there is now way to undo the mixing.

Then a year or so ago I come across Ultimate Vocal Remover and it does the impossible. It removes the bass, or vocal or drum stem from an already mixed track. We train it by basically showing it a mixed track and the bass track and say, "Now you do it to this song file." It's amazing and disturbing at the same time because the darn thing has figured out how to do something we can't. Not something that would take us a long time to do, something we can't do. "We've done it Jim. We've finally created a computer smarter than us! That must make you quite happy Spock?" Not real Star Trek dialog but there was some dialog like that in the M5 computer episode.

How long before we get so reliant on this technology that there is really no need to dig too deeply into problems? AI is already coding, how long before it is doing day-to-day engineering, and other such tasks? And should the power go out are we instantly back to the stone age because nobody can actually figure anything out anymore. I mean in like a hundred years of this?

Reminds me of the Star Trek episode "For the World is Hollow and I have Touched the Sky." A civilization is living inside a giant asteroid completely run by a computer. The computer starts to fail and they are helpless because no one even knows what a computer is. Lucky for them Spock does.

Anyway I'm sure we'll figure out how this will work but I think the next 5 or so years are going to be a bumpy ride.

I was waiting for a Skynet reference. I'd bet that would be the name of Starlink if it wasn't already taken.

It is a scary thought. Humans relying on machines for everything and after a generation or two no one knows how to do crap anymore. South Park made an episode where they featured this a bit. People were looking for plumbers or other trade jobs and there was so few people who still knew how to do them.
