The NVIDIA GeForce RTX 4090 is rumored to consume up to 550 watts. The upcoming card is said to be based on TSMC’s 5 nm process. The card’s power needs are expected to increase by 200 watts over its predecessor.



In the past, 350W was considered to be very high. In the future, it will exceed 500W. NVIDIA’s next generation 5nm Lovelace core RTX 4090 graphics card can even reach 550W.



The GeForce RTX 40 series is expected to launch in October 2022. It was recently confirmed that NVIDIA will be using a...

Mining Ethereum and Bitcoin with GPUs will both not be profitable by the time the 40 series releases so it's likely that won't be a problem.

That said, scalpers have been and will continue to be the largest problem.

I still don't understand why scalping new electronics hasn't been banned if for no other reason than consumer protection as warranties are almost always nontransferable.

Alt coins, and eth, are still profitable via mining. I don't expect that to end any time soon. Even if they make $5 a day, run them for years and they're profitable.

Ethereum mining only has a few months left.
 
I'll say that ~550W doesn't bother me if- and only if- there's 550W worth of performance on tap.

Granted I probably still don't want that in my room, I'll have to spring for a window unit just so I can stand to use it!


(also, there should be a variety of lower-power parts available at more familiarcomfortable TGP levels)
 
I joked about needing an separate power supply for your video card soon. Now I'm thibkijgna separate cooling solution and case.

This is possible, but I think we are going to see a pretty hard wall at ~1600W total power for the computer, and we already have PSUs that can hit or exceed that pretty easily. I wouldn't be surprised to see an "Extreme" video card require 2 of these new 600W adapters, but I don't think we'll see much beyond that.

Once you start looking to go past that, the typical 110V 15A outlet that is installed in most residential rooms is going to start tripping breakers. And that's before we even look at power draw for other items, like monitors (about 150W per, give or take), sound, lighting, other things in the room, etc.

You'll see some enthusiasts jump to 220V, or install 20A outlets (either of which are going to require either an electrician or a level of DIY that many people don't have) to keep up with higher power draws, but I think all but the most extreme are going to stay well under 1kW, with typical "enthusiast" peaking out below that ~1600W level.

And even at that level - ~1500W is equivalent to an electric space heater running on HIGH, it's really going to heat up a room, and that has to be taken into account as well. And to support 1200W TGP on a board is going to require a big cooler - you're looking past 3 slots, that's going to need some mechanical reenforcement to hold it in the PCI slot -- you may be looking at special brackets in a case, or dummy PCI tabs that allow it to plug into multiple sockets for stability, or maybe even a motherboard redesign, or we'll see the external GPU enclosure come around (we already have them on Thunderbolt, maybe we'll see them gain traction)
 
Lets not forget about the fun in getting a UPS to handle all this insanity. I had to strip down the things I have plugged into the one I use in my case. I don't remember the exact number but it's rated for around 900-1000 watts. I had my 4930K rig w/ a 2080 TI, 65" LCD, and 7.1 a/v receiver plugged into it. Mostly o.k., most of the time. However when using OC settings on the rig/card it got pretty cranky.
 
Wow. And there I was thinking that water cooling may no longer be necessary...

Thought process:

I got into water cooling because I wanted to get the most out of my overclocks, and also didn't want to listen to loud fans.

The thing is, overclocking gets more and more difficult every generation due to how smaller process nodes tend to scale less well with voltage, and due to how manufacturers are much better at binning these days than back in the day.

Also, air cooling solutions are much more effective these days.

I remember back when I randomly won the silicone lottery with a GTX470. I had it running at above 480 performance levels, but the stock blower cooler sounded like an absolute hair dryer.

Fast forward to last night. I repasted and reinstalled the air cooler on my old Pascal Titan X because it might be easier to sell that way (water loops are common on latest gen hardware, but who wants to run a water loop on older stuff?) I was impressed at how civilized the air cooler on that thing was both at stock speeds, and even if manipulated to run at 100%.

I was thinking to myself, with perf per watt increasing with every node, and overclocking becoming less and less of a thing, and air coolers being so much more civilized than they used to, maybe water cooling is slowly just becoming more trouble than it is worth?

I'd say that... it depends.

The best air coolers for GPUs are pretty good, but they've almost always been sold at a premium or in low quantities. And if you already have all the plumbing, it's probably a wash grabbing a card with a better air cooler vs. buying a new block.

CPUs, which generally don't need the same class of cooling, are 'harder' to air cool just due to the constraints of their layouts, and the better air coolers are giant hulks that are straight up in the way if you need to work around them.

Still, in a decent case with decent airflow - and this really just isn't that hard - air-cooling CPU and GPU for gaming is far from a terrible solution, especially if running 'stock boost'. It's when you start overclocking that the performance limitations and increased noise can become bothersome!

And? Go on whattomine.com and find the next most profitable coin to mine.

The issue is all the mining power that is currently being used for Ethereum will go to the other coins which will boost their difficulty accordingly and make them worthless to mine as well unless they somehow gain substantial value with the increase (almost certainly not)

Each coin that is currently profitable to mine with GPUs will likely lose 75% or more of it's profitability when the Ethereum change goes into effect.

I expect most setups will just be breaking even with power/maintenance/heat costs.
 
I'm curious what kind of air cooler they expect to work on a 550W GPU. Or a 270W CPU. Put them together in a smaller case and you have an oven sitting there.
