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. All of the "massive gains" were comparing DLSS and other optimization strategies to standard hardware rendering. Som…

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?

I mean it's like 1/6 of their revenue now and will probably keep sliding in importance over the datacenter. No real competition no matter how we would wish. AMD seems to have given up on the high end and Intel is focusing on the low end (for now, unless they cancel it in the next year or so).

Many American homes already have 240V sockets (eg: NEMA 14-30) for running clothes dryers, car chargers, etc. These can provide over 7200W continuous power! I guess PC power supplies need to start adopting this standard.

I feel like every time I read about USA standards I inevitably discover that any and all SI standards are actually adopted somewhere in the USA - measures in the NASA, 24h clock in the army etc. Just not in the general populace. :)

The entire residential electrical grid in the USA uses 240v, split phase. One hot wire at 120v, one neutral at 0v, and one hot at -120v, out of phase with the other hot. Very rare to have anything else. It’s just that inside the building, the outlets/lights are connected to one side of the split phase connection or the other, giving you only 120v to work with. But then we have special outlets for electric clothes dryers, EV chargers, etc, which give you both hot connections in a single receptacle, for 240v.

They are intentionally keeping the VRAM small on these cards to force people to buy their larger, more expensive offerings.

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

MS Flight Simulator 2024 can consume...who knows how much.

I know my 10 GB 3080 ran out of VRAM playing it on Ultra, and i was getting as low as 2 fps because I'm bottlenecked by the PCI-Express bus as it has to constantly page the entire working set of textures and models in and out.

I'm getting a 5090 for that, plus I want to play around with 7B parameter LLMs and don't want to quantize below 8 bits if I can help it.

This is maybe a dumb question, but why is it so hard to buy Nvidia GPUs? I can understand lack of supply, but why can't I go on nvidia.com and buy something the same way I go on apple.com and buy hardware? I'm looking for GPUs and navigating all these different resellers with wildly different prices and confusing names (on top of the already confusing set of available cards).

It is frustrating speaking as someone who grew up poor and couldn't afford anything, and now I finally can and nothing is ever in stock. Such a funny twist of events, but also makes me sad.

Imagine how sad you'd be if you were still poor.

This is the #1 reason why I haven’t upgraded my 2080 Ti. Using my laser printer while my computer is on (even if it’s idle) already makes my UPS freak out. But NVIDIA is claiming that the 5070 is equivalent to the 4090, so maybe they’re expecting you to wait a generation and get the lower card if you care about TDP? Although I suspect that equivalence only applies to gaming; probably for ML you’d still need the highe…

That’s because you have a Brother laser printer which charges its capacitors in the least graceful way possible.

If my Brother laser printer starts while I have the ceiling fan going on the same circuit, the breaker will trip. That's the only thing in my house that will do it. It must be a huge momentary current draw.

Yeah, do like me, I lower settings from "ultra hardcore" to "high" and keep living fine on a 3060 at 1440p for another few gens. I'm not buying GPUs that expensive nor energy consuming, no chance. In any case I think Maxwell/Pascal efficiency won't be seen anymore, with those RT cores you get more energy draw, can't get around that.

I feel similarly; I just picked up a second hand 6600 XT (similar performance to 3060) and I feel like it would be a while before I'd be tempted to upgrade, and certainly not for $500+, much less thousands.

8Gb VRAM isn't enough for newer games though.

Games already exceed 16 GBs at 4k from years.

I exceed 16GB in Chrome.

That says more about Chrome than anything else.

I use Firefox and have an 8Gb card and only encounter problems when I have more than about 125 windows with about 10-20 tabs each.

Yes, I am a tab hoarder.

And yes, I am going to buy a 16Gb card soon. :P

Source for your 10% number?

I heard them say that in the Hardware Unboxed youtube video yesterday. I think it's this one https://youtu.be/olfgrLqtXEo

I don’t see any testing performed in that video. Did I miss it?

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 gamin…

You need as much FPS as possible for certain games for competitive play like Counter Strike. I went from 80 FPS (highest settings) to 365 FPS (capped to my alienware 360hz monitor) when I upgraded from my old rig (i7-8700K and 1070GTX) to a new one ( 7800X3D and 3090 RTX)

You really want low latency in competitive shooters. From mouse, to game engine, to drivers, to display. There's a lot of nuance to this area, which hardware vendors happily suggest to just throw money at.

Btw, if you're using gsync or freesync, don't allow your display to cap it, keep it 2-3 frames under max refresh rate. Reddit to the rescue.
