No gamers need such high VRAM, if you're buying Gaming cards for ML work you're doing it wrong.

It's Nvidia that considers them, "gaming cards". The market decides their use in reality though. Their strategy is to sell lower-VRAM cards to consumers with the understanding that they can make more money on their more expensive cards for professionals/business. By doing this, though they're creating a gap in the market that their competitors could fill (in theory). Of course, this assumes their competitors have hal…

And if you buy the cards that Nvidia says are for gaming and then complain that they don't have good specs for ML, who is the fool exactly?

tell us how to do it right.

Get your daddy's credit card and buy H100s like a serious person.

forget the post but some dude had a startup piping his 3090 to use via cloudflare tunnels for his ai saas making 5 figures a month off of his 1k gpu that handled the work load, I'd say he was doing it more then right.

And if his volume grows 100x should we expect him to run his company off gaming gpus? Just because you can do something doesn't mean you should or that it's ideal.

There's a reason large companies are buying H100s and not 4090s. Despite what you guys think, serious ML work isn't done on the consumer cards for many reasons: FP16/FP8 TFLOPS, NVLINK, power consumption, physical space, etc.

how so?

P and B frames are compressed versions of a reference image. Frames resulting from DLSS frame generation are predictions of what a reference image might look like even though one does not actually exist.

But MPEG is lossy compression which means they are kind of a just a guess. That is why MPEG uses motion vectors.

"MPEG uses motion vectors to efficiently compress video data by identifying and describing the movement of objects between frames, allowing the encoder to predict pixel values in the current frame based on information from previous frames, significantly reducing the amount of data needed to represent the video sequence"

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…

> Rasterizing results in better graphics quality than DLSS if compute is not a limiting factor. Sure, but compute is a limiting factor.

I was demonstrating the Apples to Oranges comparison. If they were both free no one would pick DLSS. It shows Rasterizing is preferable. So comparing Rasterizing performance to DLSS performance is dishonest.

it's possible, but idk why you would expect that. just to pick an arbitrary example since steve ran some recent tests, a 1080 ti is more or less equal to a 4060 in raster performance, but needs more than double the power and a much more die area to do it. https://www.youtube.com/watch?v=ghT7G_9xyDU we do see power requirements on the high end parts every generation, but that may be to maintain the desired SKU price p…

how many customers care about raster performance?

I can’t exactly compare ray tracing performance when it didn’t exist at that time. or is this a joke about rendering games no longer being the primary use case for an nvidia gpu?

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

Will NEXT decade be possible? 8k traditional rendering at 144Hz is a lot of pixels. We are seeing a 25%/3 years improvement cycle on traditional rendering at this point, and we need about 8x improvement in current performance to get there. 2040 is definitely possible, but certainly not guaranteed.

So at 2040 we might be able to render at top 2025 display specs.

Makes you wonder how far ahead displays will be in 2040. I can imagine display prices falling in price and increasing in quality to the point where many homes just have displays paneled around the walls instead of paint.

I'm generally a 1080p@60hz gamer and my 3060 Ti is overpowered for a lot of the games I play. However, there are an increasing number of titles being released over the past couple of years where even on medium settings the card struggles to keep a consistent 60 fps frame rate. I've wanted to upgrade but overall I'm more concerned about power consumption than raw total performance and each successive generation of GPU…

I think you can get a 5060 and simply down volt it some, you'll get more or less the same performance while reducing power draw sensibly.

That's probably not going to be an option for me as I wanted to upgrade to something with 16 GB of vram. I do toy with running LLM inference and squeezing models to fit in 8 GB vram is painful. Since the 5070 non-ti has 12 GB of vram there is no hope that a 5060 would have more vram than that. So, at a minimum I'm stuck with the prospect of upgrading to a 5070 ti.

That's not the end of the world for me if I move to a 5070 ti and you are quite correct that I can downclock/undervolt to keep a handle on power consumption. The price makes it a bit of a hard pill to swallow though.

240Hz or higher monitors. 4K is enough for spatial resolution then it is better to increase temporal resolution. 4K at 240Hz stops looking like looking at a screen and starts looking out a window.

4K alone is not enough to define spatial resolution. You also need take into account physical dimensions. DPI is a better way to describe spatial resolution. Anything better than 200 DPI is good, better than 300 is awesome. Unfortunately, there are no 4K displays with 200+ DPI on the market. If you want high DPI you either need pick glossy 5k@27" or go to 6k/8k.

of course "normal viewing distances" is always implied when talking about monitors. And if you REALLY want to get pedantic you need to talk about pixels per degree. The human eye can see about 60. according to the very handy site https://qasimk.io/screen-ppd/

a 27" 1080p screen has 37ppd at 2 feet.

a 42" 4k screen has 51ppd at 2 feet.

a 27" 8k screen has 147ppd at 2 feet which is just absurd.

You have to get to 6 inches for the PPD to be 61
