- RTX 4090 - IMPROVE Performance & REDUCE Power Consumption
Nvidia's RTX 4090 has a very high power consumption, so can we fix it and improve the performance of the card whilst reducing the heat too? In this video, we'll be benchmarking Nvidia's RTX 4090, and showcasing that even dramatically reducing the power consumption of the card, the frame rate of your games is barely affected.
Indeed, reducing the power limit of the card - in some cases, can still allow us to reach higher core clocks with the GPU and improve performance of games; so you get less heat, less noise and less pain to your bank account. In this video, we examine how to change the power limit / power consumption of your RTX 40 card, (although we will focus on the RTX 4090) and how that effects your gaming and ray tracing performance. So just how can you IMPROVE your RTX 4090's performance while you REDUCE the power consumption?
The test system used here is : Intel I9 13900K, 32GB RAM, ROG Strix Gaming DDR5 motherboard, RTX 4090 gamerock card by Palit and Windows 11, using the latest drivers / software updates as of the testing.

I undervolted my 4090 FE to 0.9V at 2650Mhx frequency, 80% power limit with +1500 Memory clock to compensate. It runs equal or greater than stock with 350-375W power draw and temps at 60 C. Pure bliss
My gaming trio can't even hold +500 on the memory😑
Lolol.. all that with a severe memory overclock just to get similar to stock speeds. Sooo worth it 🙄
@@davidfaustino4476 What's the title of the video?
what is the refresh rate of your Monitor? If it's 144Hz, just limit the fps of the GPU in the Nvidia Driver. It makes the Power draw drop to 126W - 130W when gaming (at 1440p). Computerbase and IgrosLab did the test.
I actually have my RTX3080 set to 75% power limit and the performance is practically still the same but it just uses 250W of power goes to show that Nvidia has really pushed their GPU's to get every bit of performance in the cost of extra power.
It shows how pointless overclocking is nowadays. Well, it is to me anyway.
@@CH-gb7hf overclocking had been obsolete for years. All youre doing is adding extra heat for very little extra performance
@@luxemier The electricity bill 😂
@@luxemier Yeah I agree. The last thing I overclocked was an i7 920. I have never overclocked a GPU. Although there are a lot of people that will pay extra for 'overclocked' cards or they wouldn't make them. It's a bit mad hey.
lucky tbh, I have to sacrifice some FPS on my 3080 to hit that mark and in some games its enough to not be worth it imo. Nvm messing around trying to get it stable. Most people just run around for an hr and think thats stable but dont realise on low loads that it can cause crashing.
Looks like an RTX4090 under powered to 75% is the sweet spot, with 25% less expensive electricity used for an unnoticeable performance drop. Great tip, thanks!
The simplest way is just to cap your FPS. If you don't want to mess with other programs or still find using programs to tweak power a bit daunting, just cap at 60fps in the Nvidia panel, but if you're into fps shooters, capping at 120 would be better. It will lower GPU temps/power draw and give you better frame times because your fps will not jump around a lot.
It's not the best way, but it's fast and easy.....though no doubt there will still be some COD player who says they want 200+ fps.
Undervolting (for both Gpu and Cpu) is the most important tuning one can do (Especially for mobile). Better temps, lower power usage, lower fans, it's a no brainer.
Can you do the same tests for the 4080?
you forgot one point where the RTX 4090 really shines: fps limitation. IgorsLab and Computerbase made the test.
They limited the fps at 144fps, on the Nvidia Driver and the power Consumption, during Gaming (1440p, Ultra settings) went down to 126W.
Then they limited the fps to 90 and the Power Consumption went further down to 110W.
Also when DLSS3/FG is used, it draws slightly less Power.
Now add to all that the UV Curve like 2800Mhz at 0.925 or 0.900mV and you might reach 100W Power Consumption, while gaming.
I run my 4090 with 875mv.
About 30% less power for 95% performance.
On Hitman 3 at max setting including max RT I can get solid 60fps 4k DLSS Q and only uses around 200w.
So you lied. Decreasing power is decreasing performance. Just be honest...
So you lied about someone else lying. Just admit you're busted.
Check out optimumtech's video "Dont undervolt the 4090"
Yeah, I unsubscribed due to this.
Yes generally but in some cases thermal throttling is worst thing than lost performance due to decreasing the limit
@@Wobbothe3rdlol Optimum video is about 70w to gain 10 fps
Great video you just saved me from alot of stress because of high temps, you got a new sub.
Thank you :D
Ive ran mine at 70% (315w) since I bought it. I actually run it on a Toughpower GF 750 PSU. 😁
Yea me too just set powerlimit to 70% in MSI Afterburner and using an 850W psu. I don't bother to undervolt so not sure if thats an issue but it works fine
Thanks for that info I have the new 1000w Asus Thor P2 PSU. I was worried that it would not be enough because I have a RTX 4090 Asus Strix white paired with an i9 13900Ks.
@@ZackSNetwork Zac that I9 will draw a lot more power than my Ryzen 5600x. That said, you will be absolutely fine with a Thor 1000w. They are beastly PSUs. 👍
mine 1050wt psu from cooler master,but set PL to 60%.its only consume 140-160wtt when playing Apex Legend 4k 144hz med setting,way less than my prev 3070 which consume 220w,
@@natsu78999 How many hours to play Apex legends to get cost of 4090 1000++USD in return of energy bill savings by cut power draw by 80W?
looks like 80% PL would be the sweet spot.
went with 80% and didn't see a performance drop in CP or RD2.
I don’t know what am i doing here i don’t own a PC
So if we reduce video card consumption, we make it safe for the cable? Is the risk of melting the cable reduced?
3080ti at 70% - fractional difference at best and runs around 1.9GHz core at 55c.
5800x - 0.17v undervolt in 65w eco mode and still runs 4.85GHz all core at 56c when gaming.
This should be basic stuff for any enthusiast. I still need to learn memory overclocking, though...
This video does a good job of telling the average user that is not aware that underclocking and power limiting can yield good results. I like that you show people how to do undervolting and power limiting. Many people don't understand that if you get a high end gaming card you can have more enjoyment over time with it than if you buy a mid or lower end card. The high card can be underclocked to match a lower end card while still out performing it. Power limiting is really useful for games that are cpu limited. You can use more power when you need it and less when you don't need it.
What you might consider doing next is the importance of picking a good power supply beyond what is needed, so they don't run into the problem of their machine turning off while gaming... That's still a problem sadly.
Whats better for limiting PL? Geforce or msi?
I'm doing this with my 3090, but I leave the power limit at 100% and instead use undervolting + a flattened VF-curve beyond the stability & efficiency sweet spot. Near identical performance at ~80W lower power consumption (in effect an ~80% power limit), and of course thus also lower temps and lower fan speeds.
Finding a 100% stable undervolting sweet spot in *low*-load conditions may not be all that easy though ... I can push the frequencies and lower the voltage quite a bit more and achieve perfect stability in stress tests, games and benchmarks, but it will then instead intermittently crash (as in black-screen + system freeze) in low-load conditions. So, finding the best undervolt that is also 100% stable in low-load conditions was the hardest part, especially since I can't reliably reproduce the instability and have to test it using the very time consuming "let's just wait and see" method.
Great video.
It would be nice to have one standard graph and also the inclusion of temperature readouts.
I know this would be taking you a lot of time but, it will bring a lot of value.
current drivers using overlay makes battlefield 2042 crash every time.
I am running my 1070 ti undervolted. It was also power limited, until I started playing hogwarts legacy for this I needed the cards full power so I am back at 100%, which is still a heck of a lot lower than any modern card.
Would have been nice if you had explained the graphs a little. Text was hard to read
You ARE a genius! 🙌 Great tutorial, thank you!
Great video . I am using undervolting for my xtx pretty much from the start. You can set specific values for every aplication in Adrenalin Software, its very usefull as example in Cyberpunk i can easyly use 1,2 voltage without losing any performance core is pretty much always at 2590mhz, mem clock is 2580mhz. Power consumption in this case can hardly reach 300wats with 100%utilization. However I cant use this profile in witcher 3 dx 12 thus its unstable so in this game my profile has diferent values, where gpu can reach its 355 wats limit quite easyly, something is probably just tanking my gpu in this one. I can recomended this to any high-gpu user, its great and when its done well it can easyly give you more frames with much lower power consumption.
@RedGaming_Tech how do I get this ps5 mate if I've really won
I undervolt my 2060 Super (to 850mV), not a power hungry card but is ITX in an ITX case, so it counts. I'll try 75% power limit in Apex legends too though and see what happens. Any power saving is welcome these days. I do notice for my card though the PL only goes down to 71%, so...
"...does get pretty warm in the summer" Laughs in Australian.
I did some messing around with my MSI Suprim 4090 a while ago, set the PL to 90% but OC'd to +150 core and +1000 memory. Tops out at 400W and 5-7% faster than stock in a handful of benchmarks averaging as high as 2950Mhz in Firestrike Ultra. Can actually clock higher, but this setting seems pretty stable, at least enough for a few hours of gaming I did testing it out. 80% PL +100 core and +900 memory is about the same fps as stock, but at 350(ish)W.
I was trying 100 core and 1000 memory oc at 80% and got a black screen. Is the GPU more sensitive to core or memory oc?
I have a 750 watt platinum sfx psu with 4090 Suprim liquid at 80% power limit with minimal performance hit and 7700x all core ai oc at 5.65 ghz with noctua d15.
Holy of poo. I gotta get a rtx 4090. That ingame overclocking software is pretty cool. I would love to play with that
if you lock frames to your monitor you can still keep full power limit and power draw will be even lower if you disable RT or set to performance. 75 is sweet spot. I wish i wasnt paying 17 cent for my electricity......I dont worry about temps on my FE with active water blocks more so power draw, i had 3080ti last year at 75 percent but never undervolted as i should because that coil whine was bad on the hydro block edition.
4K draws a lot of power, if you have a 1440p monitor it will upscale but sometimes it can look better than in some games. 4K monitors are expensive and electricity isnt low enough to warrant the extra power draws from both ends.
Can someone name the game at 2:23 and I like running my RTX 4090 card at 3000Mhz
I will have to do this to my 4080 see if it makes a difference
@user-jq8rr9yf3p scammer alert. You people need to get a life
When i change maximum power to say 80% (using nvidia software) when the pc is reset it doesnt remember and sets it back to 100%. How do i make it remember my settings?
NEVER.! Mooooore Powwwwwerrrrrr 🤣 Seriously though, nice video👍🏻
my 4090 now barely even goes over 350 and never hits 400 watts lmfao...card is a beast in performance
Considering that my 4090 rarely exceeds 350W, I can see why a 80% power limit has minimal effect on performance. And doesn’t that also mean that I’m not saving any $$ or decreasing heat output since the GPU wasn’t going to run that high regardless???
@RedGaming_Tech I’ve never been so excited! But no thanks, I don’t need a PS5
Shouldnt title be MAINTAIN performance & Reduce Power Consumption?
I just FPS limit my games. My monitor is a 120 Hz panel, so there's no need to get 200+ FPS. The only game I have that pushes my card is ARK, otherwise it's always limited by the monitor.
Anyone know what is going on with afterburner? I heard support stopped for some time due to politics. Anyways - wondering if afterburner has received updates regarding the 4090? Not really anything to worry about with undervolting but still don't want to risk my 4090 and I've heard lots of good things about afterburner.
I believe MSI has sorted the situation out with the developer.
I found the best efficiency to be around 63% power level.
How many watts is that maxing at Dubs?
I did undervolting of my RTX 4090, but I wish to go lower than 250w in power draw I don't need more than 75 fps to play games. Can someone tell me how to achive it?
this dude sounds like Jeremy Clarkson with a slightly deeper voice
This is great news for all 3 of your followers who have a 4090. 😂
My 6800xt is undervolted and overclocked.
i think that the reason why they cant put a 4090 chip in a laptop is not worth because at 40% power get alot lose
There are 4090 laptops. They operate at 175w tgp for the GPU, performance is around a desktop 3090.
@@Wobbothe3rd the 4090laptop is a 4080 desktop chip undervolted the 4080 have less cores
Just get the right model and avoid FE at all costs
After spending $10,000 on rtx 4090s, I returned all of them and only kept the gaming OC version. FE coil whine is horrid. My gaming oc is running quiet without ANY limits. Stop with the undervolting, stop limiting power. You are introducing unstabiliy issue that is nightmare to troubleshoot. Why are you handicapping your gpu after spending $2000 🤣😂🤣😂
100% this.
Good choice. I have the Gaming OC too and it's fantastic. It's just good at everything. Higher-end features, good cooling, good overclocker, no coil whine even at high fps. I originally was going to get a different model but the guy at Microcenter said the Gaming OC and Zotac Trinity were the only ones they had in stock at the time. Looking back, I am glad he didn't have the one I was going to get because the Gaming OC is amazing and I wouldn't trade it for any other model.
80% power limit +160 core +1000 memory, 3% faster than OEM
What brand do you own? Can't match those values on my PNY.
4090 great card, terrible value. I guess even the 1 percenters need to say they are energy efficient.
I love my 4080 for 1030 dollars
Horseshit
I reduced my power consumption even more. I just did not buy it.
4060 vs 3070 what and why and are we even upgrading gens....

As someone who cares about power consumption to a rational degree: I don't own a 4090 in the first place.
Can you really get away with running a 13900k and 4090
Title is clickbait. Better to spend a minute around it when making it.
But if you mean lower heat and power consumption could be described/marketed as better performance, rgen you are absolutely correct in "Nvidia way to be sold".
Btw who would be getting 4060, first of all it not yet released and in 4000 series price performance scaling among tiers it gonna be DOA of century.
I have cut power limit on my MSI Mech 6650xt which is only possible thing to do with pwr limit by 10percent, then set voltage to 1,125V from default 1,2 and core clock to 2635MHz from 2765. But mainly I have reduced max fps to monitor capability, thats what does big job in your terms. Unseen fps are waste of energy.
If you did not get a free review sample of the 4090, people paid 2000$ for their card, so they can likely afford the power bill as well. So who the f... cares? It's totally irrelevant for 98% of us.
The 4090 sold hundreds of thousands of units. Speak for yourself, broke boy.
I care about the heat output and fan noise.
@@transistorjump919 I was more referring to my case fan noise. Fair point though
YAWN
99th first
First
No one cares about a $1600+ GPU
Obviously the 100Ks who bought it do.
if you can afford a 4090 you don't care about energy bills, its like asking a Urus driver if they care about their gas prices
That realy depends my family is kinda well situated... but we are not happy with 900euro bills for just electrocity, trust me. Here in Czech electrocity is sometimes 3xtimes more expensive then in USA. Its madness.
That's not true. Some of us have solar and desire to be carbon neutral.
Btw using gpu with 450wats all time could be kinda insane my case 250usd per mouth. So I care about it.
Im a 4090 owner and I still do, if i can set power limit at 80% at the cost of -2% fps in my games i dont see why not? Also keeps the temp of my room down with it running at flat 60degrees max.
I f you have thousands of dollars for just a GPU im sure you are not a tree hugger or care about power
