Similar CUDA core counts for most SKUs compared to last gen (except in the 5090 vs. 4090 comparison). Similar clock speeds compared to the 40-series. The 5090 just has way more CUDA cores and uses proportionally more power compared to the 4090, when going by CUDA core comparisons and clock speed alone.

I started thinking today, when Nvidia seemingly keeps just magically increasing performance every two years, that they eventually have to "intel" themselves, where they haven't made any real architectural improvements in ~10 years and just suddenly power and thermals don't scale anymore and you have six generations of turds that all perform essentially the same, right?

Performance per watt[1] makes more sense than raw power for most consumer computation tasks today. Would really like to see more focus on energy efficiency going forward. [1] https://en.wikipedia.org/wiki/Performance_per_watt

That's s blind way to look at that imho. Doesn't work on me for sure. More energy means more power consumption, more heat in my room, you can't escape thermodynamics. I have a small home office, it's 6 square meters, during summer energy draw in my room makes a gigantic difference in temperature. I have no intention of drawing more than a total 400w top while gaming and I prefer compromising on lowering settings. Ene…

Increasing performance per watt means that you can get more performance using the same power. It also means you can budget more power for even better performance if you need it.

In the US the limiting factor is the 15A/20A circuits which will give you at most 2000W. So if the performance is double but it uses only 30% more power, that seems like a worthwhile tradeoff.

But at some point, that ends when you hit a max power that prevents people from running a 200W CPU and other appliances on the same circuit without tripping a breaker.

Sounds to me like they made "massive gains". In the end, what matters to gamers is 1. Do my games look good? 2. Do my games run well? If I can go from 45 FPS to 120 FPS and the quality is still there, I don't care if it's because of f…

Rasterizing results in better graphics quality than DLSS if compute is not a limiting factor. They are trying to do an apples to oranges comparison by comparing the FPS of standard rendering to upscaled images. I use DLSS type tech, but you lose a lot of fine details with it. Far away text looks blurry, textures aren’t as rich, and lines between individual models lose their sharpness. Also, if you’re spending $2000 f…

> if compute is not a limiting factor.

If we're moving towards real time tracing compute is going to always be a limitting factor, as it was in the days of pre rendering. Granted currently raster techniques can simulate ray trace pretty well in many scenarios and looks much better in motion, IMO that's more limitation of real time ray trace. There's a bunch of image quality improvements beyond raster to be gained if enough compute is throw at ray tracing, i think a lot of dlss / frame generation goal is basically to offload more cpu to generate higher IQ hero frames while filling in blanks.

The 5090's core increase (30%) is actually underwhelming compared to the 3090->4090 increase (60% more), but the real game changer is the memory improvements, both in size and bandwidth.

Fake frames, fake gains

The fps gains are directly because of the AI compute cores, I’d say that’s a net gain but not a the traditional sense preAI.

DLSS 4 uses a completely new model with twice as many parameters and seems to be a big improvement.

I hope so, because it looks like 8k traditional rendering won’t be an option for this decade.

Why is that an issue? Do you have an 8k monitor?

Fake frames, fake gains

The human eye can't see more than 60 fps anyway

The human eyes are analog low pass filters, so beyond 60Hz is when things start to blur together, which is still desirable since that's what we see in real life. But there is a cutoff where even the blurring itself can no longer help increase fidelity. Also keep in mind that this benefit helps visuals even when the frame rate is beyond human response time.

At what point did we stop calling them phones?

Compute cards, AI Cards, or Business Cards. I like business cards, I'm going to stick with that one. Dibs.

Business Cards is an awesome naming :)

5090 has 2x the core, higher frequencies, 3x flops. You got to do some dd before talking

I wonder how many generations it will take until Nvidia launches a graphics card that needs 1kW.

I wish mining was still a thing, it was awesome to have free heating in the cold winter.

Is it not? (Serious question)
