NVIDIA GeForce RTX 4080 Could Get 23 Gbps GDDR6X Memory with 340 Watt Total Board Power
NVIDIA's upcoming GeForce RTX 40 series graphics cards are less than two months from the official launch. As we near the final specification draft, we are constantly getting updates from hardware leakers claiming that the specification is ever-changing. Today, @kopite7kimi has updated his GeForce RTX 4080 GPU predictions with some exciting changes. First off, the GPU memory will get an upgrade over the previously believed specification. Before, we thought that the SKU used GDDR6X running at 21 Gbps; however, now, it is assumed that it uses a 23 Gbps variant. Faster memory will definitely result in better overall performance, and we are yet to see what it can achieve with overclocking.
Next, another update for NVIDIA GeForce RTX 4080 comes with the SKU's total board power (TBP). Previously we believed it came with a 420 Watt TBP; however, the sources of kopite7kimi claim that it has a 340 Watt TBP. This 60 Watt reduction is rather significant and could be attributed to NVIDIA's optimization to have the most efficient design possible.

If you don’t limit the heavy industry globally , not just in Europe or America or Asia, that’s the main cause of the climate change, it’s worthless doing anything else.
It’s a matter of scale.
You are doing nothing by using 1000 electric vehicles while just one old truck in Europe or china or Africa or America or wherever consumes and pollutes 100 times more.
Well here is the latest 4000 series rumors from me. Rtx 4000 is just a revamped rtx 3000 series cards. I mean nvidia has done it before... Just saying.
Its 100W/hr on a GPU. Its a minute or two less under warm water. Its a few hundred kwh yearly because of solar. Etc etc etc
It really does matter, because our footprints are far too high overall. None of us with the wealth to buy these products have any right to point fingers...
That heavy industry and its processes exist because we buy into it. Every time. We have the power to kill a portion of it.
Rtx 4090ti 700tdp on peak time, sure don't forget models like kinping or half of fame.
If they actually want to shift any cards, 4080 should be $500 or less and 300w or so.
We want faster cards that are more efficient. Those 2 things are not interchangeable. Typically, you sacrifice one to make the other.
The good thing is it is a lot easier to grow plants and live in warm environments than cold. For example, Antarctica has a population of less than 1000, while millions of people live in the Sahara desert.
We're also are in no way talking about 5% performance improvement and older cards could also push more power when modded to do so, there's a lot of diminishing returns with power increase, it just so happens that nvidia now feels the need to go to those lenghts. That's just... dumb.
Edit: Added Horizon: Zero Dawn
I did some tests recently with my 6600XT, an efficient card to begin with but which is still overclocked out of it's efficency range out of the box.
Default core clock: 2668 MHz, ~2600 MHz in-game, 16Gbps Mem, 132-150W (Power +20%), 1.15v
Overclocked: 2750 MHz, ~2690 MHz in-game, 17.6Gbps Mem, 145-163W (Power +20%, hits power limits), 1.15v
Underclocked: 2050 MHz, ~2000 MHz in-game, 16Gbps Mem, 70-75W, 0.862v
But what of performance? Canned game benchmark runs as I'm no in-game consistent benchmarker:
R5 5600, 3200 MHz CL16, 1440p, PCIe 3.0 (B450 board), no Motion Blur
CP2077 - 18% lower fps at High settings
SotTR - 12% lower fps at HUB rec settings (~High but better visuals)
Forza Horizon 4 - 17% lower fps at Ultra settings
Horizon: Zero Dawn - 16% lower fps at Favor Quality settings (High)
1% lows were about the same in CP2077 (need to do more runs at 2690 to confirm), -13% in SotRT and -14% in FH4, -11% in H:ZD.
So about a -15% FPS tradeoff for half the power usage. Comparing runs directly to each other, the 2000MHz test used 51% of the power of the 2690MHz tests in the same games (148W in CP2077 and SotTR vs 75W, 118W in FH4 vs 60W, 139W in H:ZD vs 71W).
15% fewer frames is a lot and it's not a lot, depending on what you're looking for.
If you don’t like it….. don’t buy it. Nobody is forcing you to buy a 4080. You can buy a 4070 or 4060 with the power draw you desire, and better performance, and save money! Win win! 20 w is insane now. Rediculous.
What i do know is that a 1080 uses 50% less power. Thats significant. It was the segment I used to buy into. Thats also significant; shit escalated damn quickly. And for what?! A few realtime light rays?
No 'founders/reference model' did, but AIB's certainly did and the high end of the stack still had 250w+ parts, like Dual GPU cards, same for AMD.
Also AMD single GPU between Fermi and current generation:
- R9 290/390 - 275w
- R9 290X/390X - 290w/275W
- R9 Fury X - 275w
- Vega 64 - 295w
- Radeon VII - 295w
Winning Logic. I also consistently see a lot of complaints from what amounts to people who would've never bought the card anyway, even if it fit their power budget, because of things like brand and price.Well everyone needs something to buzz about :cool:
Your 125w GFX card is a disgrace to future generations, when power is only going to cost more and the planet is heating up, we're in a recession and next summer is set to be the hottest on record!
Responsible gamers should all limit themselves to sub 30w draw for the entire device, or you'll be answering to my sweaty, poor grandchildren dammit.
Again BS, pretty sure your online shopping is an ecological disaster ~
Like I was harping in the other thread you've got to stop the rot starting from oneself, no point blaming a$$hole corporations or other individuals if you aren't doing more than the bare minimum at your end. Glad one of the more sane voices out there picked up on this!
What's your per capita energy/resource consumption in the West? Wanna try that again :rolleyes:
