32GB of GDDR7 at 1.8TB/sec for $2000, best of luck to the gamers trying to buy one of those while AI people are buying them by the truckload. Presumably the pro hardware based on the same silicon will have 64GB, they usually double whatever the gaming cards have.

Why do you need one of those as a gamer? 1080ti was 120+ fps in heavy realistic looking games. 20xx RT slashed that back to 15 fps, but is RT really necessary to play games? Who cares about real-world reflections? And reviews showed that RT+DLSS introduced so many artefacts sometimes that the realism argument seemed absurd.

Any modern card under $1000 is more than enough for graphics in virtually all games. The gaming crisis is not in a graphics card market at all.

The most interesting news is that the 5090 Founders' Edition is a 2-slot card according to Nvidia's website: https://www.nvidia.com/en-us/geforce/graphics-cards/50-serie... When was the last time Nvidia made a high end GeForce card use only 2 slots?

Fantastic news for the SFF community. (Looks like Nvidia even advertises an "SFF-Ready" label for cards that are small enough: https://www.nvidia.com/en-us/geforce/news/small-form-factor-... )

It's a dual flow-through design, so some SFF cases will work OK but the typical sandwich style ones probably won't even though it'll physically fit

575W TDP for the 5090. A buddy has 3x 4090 in a machine with a 32 core AMD cpu must be putting out close to 2000W of heat at peak if he switched to 5090. Uff

Even though they are all marketed as gaming cards, Nvidia is now very clearly differentiating between 5070/5070 Ti/5080 for mid-high end gaming and 5090 for consumer/entry-level AI. The gap between xx80 and xx90 is going to be too wide for regular gamers to cross this generation.

The price of a 4090 already was ~1800-2400€ where I live (not scalper prices, the normal online Shops) We'll have to see how much they'll charge for these cards this time, but I feel like the price bump has been massively exaggerated by people on HN

MSRP went from 1959,- to 2369,-. That's quite the increase.

3 Generated frames sounds like a lot of lag, probably a sickening amount for many games. The magic of "blackwell flip metering" isn't quite described yet.

It’s 3 extrapolated frames not interpolated. So would be reduced lag at the expense of greater pop-in. There’s also the new reflex 2 which uses reprojection based on mouse motion to generate frames that should also help, but likely has the same drawback.

it's certainly not reduced lag relative to native rendering. It might be reduced relative to dlss3 frame gen though.

Pretty interesting watching their tech explainers on YouTube about the changes in their AI solutions. Apparently they switched from CNNs to transformers for upscaling (with ray tracing support) if I understood correctly though for frame generation makes even more sense to me.

32 GB VRAM on the highest end GPU seems almost small after running LLMs with 128 GB RAM on the M3 Max, but the speed will most likely more than make up for it. I do wonder when we’ll see bigger jumps in VRAM though, now that the need for running multiple AI models at once seems like a realistic use case (their tech explainers also mentions they already do this for games).

Double the bandwidth, double the ram, double the pins, and double the power isn't cheap. I wouldn't be surprised if the profit on the 4090 was less than the 4080, especially since any R&D costs will be spread over significantly less units.

There have been numerous reports over the years that the 4090 actually outsold the 4080.

The 4080 was also quite the bad value compared to the much better 4090. That remains to be seen for the 5000 series.

Seems kinda silly to make an 8K video card when ... nobody on the planet has an 8K screen

> Seems kinda silly to make a 4K video card when ... nobody on the planet has a 4K screen. Someone else probably said that years ago when everyone was rocking 1080/1440p screens.

First consumer 4K monitors came out more than a decade ago. I think the Asus PQ321 in 2013. That’s close to where we are now with 8K.

How many of the cards of that time would you call “4K cards”? Even the Titan X that came a couple of years later doesn’t really cut it.

There’s such a thing as being too early to the game.

I have a feeling regular consumers will have trouble buying 5090s.

RTX 5090: 32 GB GDDR7, ~1.8 TB/s bandwidth. H100 (SXM5): 80 GB HBM3, ~3+ TB/s bandwidth.

RTX 5090: ~318 TFLOPS in ray tracing, ~3,352 AI TOPS. H100: Optimized for matrix and tensor computations, with ~1,000 TFLOPS for AI workloads (using Tensor Cores).

RTX 5090: 575W, higher for enthusiast-class performance. H100 (PCIe): 350W, efficient for data centers.

RTX 5090: Expected MSRP ~$2,000 (consumer pricing). H100: Pricing starts at ~$15,000–$30,000+ per unit.

Looks like most of the improvement is only going to come when DLSS4 is in use and its generating most of the frame for Ray Tracing and then also generating 3 predicted frames. When you use all that AI hardware then its maybe 2x, but I do wonder how much fundamental rasterisation + shaders performance gain there is in this generation in practice on the majority of actual games.

> but I do wonder how much fundamental rasterisation + shaders performance gain there is in this generation in practice on the majority of actual games.

likely 10-30% going off of both the cuda core specs (nearly unchanged gen/gen for everything but the 5090) as well as the 2 benchmarks Nvidia published that didn't use dlss4 multi frame gen - Far Cry 6 & A Plague Tale
