That's what I'm wondering. What's the actual raw render/compute difference in performance, if we take a game that predates DLSS?

Based on non-DLSS tests, it seems like a respectable ~25%.

Respectable outright, but 450W -> 575W TDP takes the edge off a bit. We'll have to see how that translates to at the wall. My room already gets far too hot with a 320W 3080.

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.

Primarily concerned about the memory bandwidth for training. Though I think I've been able to max out my M2 when using the MacBook's integrated memory with MLX, so maybe that won't be an issue.

Training is compute bound, not memory bandwidth bound. That is how Cerebras is able to do training with external DRAM that only has 150GB/sec memory bandwidth.

most household circuits can only support 15-20 amps at the plug. there will be an upper limit to this and i suspect this is nvidia compromising on TDP in the short term to move faster on compute

So you are saying that Nvidia will finally force USA to the 220V standard? :)

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.

If the VRAM wasn't small, the cards would all get routed to non gaming uses. Remember the state of the market when the 3000 series was new?

Then they should sell more of them.

Why sell more when you can sell less for more

1. Because you shoot at puddles? 2. Because you play at night after a rainstorm? Really, these are the only 2 situations where ray tracing makes much of a difference. We already have simulated shadowing in many games and it works pretty well, actually.

I just find screen space effects a bit jarring

Indeed you're not a gamer, but you're the target audience for gaming advertisements and $2000 GPUs. I still play traditional roguelikes from the 80s (and their modern counterparts) and I'm a passionate gamer. I don't need a fancy GPU to enjoy the masterpieces. Because at the end of the day nowhere in the definition of "game" is there a requirement for realistic graphics -- and what passes off as realistic changes fro…

I play roguelikes too

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).

OK so there are a handful of effects at work at the same time. 1. Many people knew the new series of nvidia cards was about to be announced, and nobody wanted to get stuck with a big stock of previous-generation cards. So most reputable retailers are just sold out. 2. With lots of places sold out, some scalpers have realised they can charge big markups. Places like Amazon and Ebay don't mind if marketplace sellers ch…

The workstation cards have MSRPs. The RTX 6000 Ada’s MSRP is $6799:

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.

> Gaming cards for ML work you're doing it wrong

lol okay. "doing it wrong" for a tenth of the cost.

>A 3090 is $1000 right now. Not really worth it if you can get a 5090 for $1,999

If you can get a 5090 for that price, I'll eat my hat. scalpers with their armies of bots will buy them all before you get a chance.

Do you have a recipe in mind for preparing your hat for human consumption or is your plan to eat it raw?

a 4070 has much better performance for much cheaper than a 3080...

Any the 4070 Super is relatively available too. I just bought one with only a small amount of hunting. Bought it right off of Best Buy, originally tried going to the Microcenter near my parent's house while I was down there but should have bought the card online for pickup. In the 2 days between my first check and arriving at the store ~20 cards sold.

What was the drop in 3070 pricing when the 4070 was released? We should expect a similar drop now I suppose?
