Why is that a problem though? Newer and more GPU intensive games get to benefit from DLSS 4 and older games already run fine. What games without DLSS support could have done with a boost?

I've heard this twice today so curious why it's being mentioned so often.

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.

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 half a brain cell (I'm looking at YOU, Intel! For fuck's sake give us a 64GB ARC card already!).

The increasing TDP trend is going crazy for the top-tier consumer cards: 3090 - 350W 3090 Ti - 450W 4090 - 450W 5090 - 575W 3x3090 (1050W) is less than 2x5090 (1150W), plus you get 72GB of VRAM instead of 64GB, if you can find a motherboard that supports 3 massive cards or good enough risers (apparently near impossible?).

I got into desktop gaming at the 970 and the common wisdom (to me at least, maybe I was silly) was I could get away with a lower wattage power supply and use it in future generations cause everything would keep getting more efficient. Hah...

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.

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.

Energy consumption can't keep increasing over and over forever.

I can even understand it on flagships, they meant for enthusiasts, but all the tiers have been ballooning in energy consumption.

Games already exceed 16 GBs at 4k from years.

We all know DLSS4 could be compatible with previous gens.

Nvidia has done that in the past already (see PhysX).

DCS World?

I’m really curious what training is going to be like on it, though. If it’s good, then absolutely! :) But it seems more aimed at inference from what I’ve read?

I was wondering the same thing. Training is much more memory-intensive so the usual low memory of consumer GPUs is a big issue. But with 128GB of unified memory the Digits machine seems promising. I bet there are some other limitations that make training not viable on it.

It will only have 1/40 performance of BH200, so really not enough for training.

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.

You underestimate how many gamers got a 4090.

You don't need to run them in x16 mode though. For inference even half that is good enough.
