Hey all. Some notes: - To clarify, the recording of the software is just to show you where the settings are. These are NOT the settings used for this test and like I said, you'll need to find the right settings for your own specific GPU. - The RTX 4070 Starfield result has been updated with the latest Nvidia driver installed, so it's up about 5% from the data you saw last week. Still far behind AMD unfortunately. - REMINDER: I will NEVER reply to your comment asking you to text a number or send a telegram message. Please do not fall for those scams!

[@sandornyemcsok4168]

Hello Nada, do you plan to test the undervolt on the 7700XT as well? I cannot know for sure, but I think the 7700XT is pushed up even higher on the efficiency curve, thus undervolting it can deliver even better results. I am hesitating to buy a 7700XT and this is a key factor in the decision. 😊

Excellent video, undervolting is king nowadays, looking forward to more videos like this.

[@MrDreaqu]

Awesome! thank you @techtesters. One trick i used to do with underclock and undervolt was to run a demanding game, for instance any recent battlefield game, run hwinfo and see what the average clocks would be and set it to that for a start :) Probably disabling the constant turbo hunting would lower temps as well.

[@Bundy714]

Nada, you are killing it with your videos!!! Putting out some of the best tech content on KZbin!

[@Kizarat]

Thanks for the video. I honestly believe undervolting + slightly underclocking a GPU is worth the mild performance loss to help increase its longevity, especially with a locked frame rate. I have an undervolted + slightly underclocked 6700 XT and locked my frame rate to 90 FPS with Radeon Chill. Keeps power draw low, temperatures cool and framerate consistent.

[@str8chillaxin]

Excellent tutorial! I undervolt my 6900XT with extremely similar tuning. I set power limit to -10% and voltage to 960mV. Min 2600 MHz, Max 2700 MHz. VRAM fast timing and max out frequency at 2150 MHz. This has actually increased my performance in most games and runs at 100W lower than default or default undervolt settings down to around 250W under load. I may have a rare case where the default is slower, but manually tuning the MHz to 100MHz window is what really worked well. I may have actually been throttling due to hitting hotspot 90 degree temps with stock settings even with the Sapphire Toxic Nitro which has radiator cooling

[@darkfire3691]

If your Sapphire Nitro thermal throttles, something is very wrong with either card itself or case. It's impossible to thermal throttle with 360mm rad, even with 500 watts.

[@str8chillaxin]

Play Rust for 6 hours with hwmonitor open and you will see the hotspot hitting above 90 using default settings@@darkfire3691

[@josecangrejo3086]

In RDNA 2 that 960mv seems quite low, most likely not stable.

[@str8chillaxin]

it is very stable. I have been using it for months@@josecangrejo3086

[@biansanity]

are you tested your settings on 3dmark? because no way I your settings is stable with voltage that low and clock speed that high! I have myself a 6900xt RDU and I can't even reach 1000mV with any clock settings without crashing.

[@mordacain3293]

Nice overview of the process. Of course, the buyer will also need to consider that you can also undervolt the alternative, which is arguably more effective. On my 4070, for reference, performance is equivalent but average power draw is now around 140 watts (975mV@2700Mhz). One could argue that UV is an easier proposition on AMD as the tuning features are built in to the software stack while Afterburner (or some equivalent 3rd party utility) is needed for nVidia. All of that being said, the additional VRAM and more attractive pricepoint of the 7800XT would probably have swayed me had I not already caved on the 4070.

[@dontowelie1302]

Great contend :)

[@mordacain3293]

​@@Nayah9 Messy, really? You ever use GeForce Experience or the antiquated control panel? AMD's software stack is cleaner / more intuitive to use in virtually every capacity. One could make the argument undervolting might be easier on Afterburner but nVidia has no alternative that they own and develop themselves. Maybe you are unaware, but Afterburner could go away at any time (like when MSI stopped paying the dev at the start of the Ukrainian conflict). All of that being said, it's not like you can't use Afterburner to UV/OC Radeon cards if you prefer that interface.

[@Davinmk]

@@Nayah9nividia control pannel is ugly and so is msi afterburner.

[@henrikw377]

I was going to add this as well. I run my 4070 (Palit GamingPro) at 1000 mV, 2850 core clock, +1100 memory clock, and in most games I'm basically capped at 150 W power draw. (Some games go up to 180, not sure what the difference is.) Not a massive performance gain over stock on this card (~2% in benchmark), but it's generally there even at lower power draw.

[@Nayah9]

@@mordacain3293 Yeah, I mainly use GeForce Experience for the automatic driver updates and for the easy-to-setup overlay. Nothing wrong with it. I don't get your point. I'm purely referring to undervolting software. Afterburner is undeniably better. Can you even do a custom curve on AMD software? That's pretty important for undervolting. I'm not anti-AMD or anything. My PC runs on a 7950X and I love it. I'm just saying undervolting on AMD software looks a lot more convoluted and less effective than Afterburner. Afterburner is not going away anytime soon. You're referring a story from about a year ago where it looked like the funds might be cut, but that has long been resolved and it only happened once, while Afterburner is decades old. And yeah, I know you can use Afterburner with AMD GPUs. So why don't you?

@@TechTestersMost Welcome! Thank you for taking the time to respond! You have a new Sub because of this power draw approach to graphics cards! Please PLEASE cover this more and with new cards as they come on the market. This is something that needs more attention as GPUs become ever more power hungry! As a gamer that plays for a lot of hours per day in the UK (where we have a high energy cost like you in the Netherlands), this is a key issue and I hope you produce more videos on this key topic! I'm currently using a 1080 Ti but shopping for a new card. Power draw vs performance is a key issue for me to consider over the initial investment cost. I'm not someone who replaces my graphics card ever two years (and OC my card accordingly!). I run my system in as low power (not overclocked) to extend the component life time. Yet this seems to be ignored by the vast majority of presenters who expect components to burn out in no time and accept this cost hit for performance. Performance vs power draw vs purchase price is a key issue to me.

In the 2k’s I was an avid overclocker💪🚀. The past ~7years I’ve switched to being an avid undervolter ⚡⚡with my CPUs and gpus as I’ve been into ITX PCs🥰💪😇 (since Intel 4th Gen) and it’s proven to be worthwhile for me. I get a vg reduction in power draw, waaaay better temps and noticeably quieter fans🤩🥳etc! While it’s not for everyone, slower speeds on CPUs / GPUs doesn’t result (as shown here) in much of a fps reduction. Great video Nada and I think as many people are building smaller systems MATX / ITX these days, this video is going to prove more worth while.

[@hollisbostick2872]

Thanks so much for this. It's already annoying (if understandable) that so many tech channels focus on pricing in the U.S., which is rather different than here in The Netherlands. Then, in the parts of the review/discussion that I don't ignore as useless to me, many gloss over the power issue as a brief side note (I guess power is cheap in North America, since Canadians don't seem to pay much attention to it either). I really, really appreciate that you focus on these concerns that Europeans -- and specifically Nederlanders -- might have when making buying decisions. And I'm *extremely* glad to have a reason to turn my face from the 4070 and towards the 7800xt 🙂. 👍🏾!

[@RedCnMn]

Yeah, I mean I just bought the 7800XT either way bc AMD seems much better at the price-performance ratio than Nvidia. But now with this video, its even better to know that I can keep high fps while saving some power. It could also help with the longevity of this graphics card.

Assuming this will also help with the 7700xt, could it matter from which model you buy? Because you also have the hellhound which is even more quieter as well as cooler. Maybe it runs with less power as well. Also, isn't there an easier way to undervolt? I thought I read somewhere you could activate auto undervolt. But that still goes specifically above 200w isn't it? So for this you needed to undervolt yourself right?

[@TerraWare]

I'm a big fan of tweaking settings towards efficiency, primarily with knocking down the fan noise and amounts of heat output but also saving a bit on electricity is a good thing. Other than undervolting technologies like FSR and DLSS mixed with a framerate cap are also amazing tools. For example I'm playing Lies of P on a pretty high end build on an ultrawide 3440 x 1440 and with DLSS on Quality with a 120fps cap gpu is drawing 110 watts from the close to 400 it would draw if I was running native without a framrerate cap.

[@FietserRTCW]

I'm now using a 60 fps cap with dlss balanced and undervolting on a 4060 ti, the savings are amazing without sacrificing any quality.

[@MoritzRW]

Thanks for the video. I have my card undervolted to 1010mv@2520MHz(Stock) and its stable. But when i lower my clock from 2520 to 2400Mhz its unstable. Do i miss something? I also made my VRAM a little faster, could this be the issue?

[@mrmanders8910]

Omg wist helemaal niet dat je Nederlands was!! Awesome!!!

[@TVsBen]

Interesting. The undervolt was most likely where AMD originally targeted the reference card to run, but then they turned it up when it couldn't consistently beat the RTX 4070. Once you take into account the fact that the RX 7800 XT is also a fair amount cheaper than the 4070, it looks like a big win...if you can live without DLSS and don't mind the reduced ray tracing performance, at least.

[@AR-bj5et]

Perfect video at the perfect time! Looking to spec a new PC that'll be 4k capable for a while but the UK's not looking so good right now with the energy crisis. It's nice to see something that helps make the choice between a VRAM bottleneck in 1-2 years or particularly chilly Winters.

[@TechTesters]

If you're going after 4K, I would seriously consider the benefits of DLSS as well. I'd say the 7800 XT is best at 1440p.

[@AR-bj5et]

@@TechTesters No one can predict the future but if you had to guess, how risky is it opting for a 12gb VRAM card as potential 4k budget option this year compared to say 3+ years? Are we fooling ourselves if we think anything less than a 4080 has realistic longer term potential?

[@TechTesters]

I wish I had an answer to that. I do agree that if you're serious about 4K, 4080-4090 is the way to go, but it's not exactly cheap.

[@Omizuke]

Thank you so much for this video. As someone that it's getting rip off by my power company, and the only one here. And Solar isn't an option. It bothers me how rarely Power Efficiency is touch by reviewers and usually just brush over. Some of us are able to buy GPUs because we save for years. Money is still tight. And when you are on the .30 and .40s per kWh. it does adds up. And there is no reason to waste energy if you don't have to. When I got my 3060 ti, although I didn't think it was the best fps per dollar. Compare to some other options. Undervolting it and power limit, gave me similar performance, sometimes better. With lot less power, less fan noise, lower temps. And my TV has a 60hz panel so reaching 60 or close and within VRR ranges is good enough for me.

[@zervox8427]

undervolting your GPU or CPU or memory will never cause the hardware harm, never, it is physically impossible to bring hardware damage by reducing the voltage. you still do however have the same risk as with overclocking/overvolting of file corruption when a crash or bluescreen happens or unstable memory during file copying,writing,reading etc due to instability, but this is not hardware damage. this is why a good recommendation after having tuned your hardware even if you've had no crashes and then tested for stability, is to make sure that during your tuning that you have not gotten any corrupted system files, so doing a sfc scan etc is a good precaution, last thing you want is to have a corrupted file keep being corrupted for a long time, because it might be corrupted in a way that the system still works, but over time it will read from the corrupted data and apply that as a value elsewhere, which might work fine for a while, but suddenly not work fine anymore later down the line.

Great video again! Question as a fellow Dutch person. I am trying to a good site to buy the 7800 XT in the netherlands, any tips? is the Asrock 7800 xt challenger/phantom on Megekko any good?

[@TechTesters]

I can’t say anything about the Asrock. They blacklisted us a few years back and I have zero reasons to buy one of their cards. I would personally get a card that has been reviewed positively.

[@Svartie]

Great video. Possibility for same video for 7900 xt? Just bought an Sapphire, and it's my very first time trying AMD gpu. Problem is, card was like 200e cheaper than 4070 ti, but EU electricity costs are insane, and wanna keep it under 300w.

[@TechTesters]

Thanks! You can definitely improve the 7900 XT efficiency as well, but each card will require different tuning. Keeping it below 300W should be easy.

[@Svartie]

@@TechTesters Thank you for your response. I just wanna make sure, everything will be ok, without harming the card. It's ok if i try same settings as your video, or should i try different settings until card will stay stable under 300w? Sorry for asking that much. I'm not experienced at all with such matters, and it's the first time using AMD graphics card. Nvidia control panel was simple for me before, but AMD's seems a bit overwhelming 😊

[@zagorim7469]

Interesting. I currently run an RTX 2080 which is undervolted too. But I think it might make more sense to go for a lower profile non OC card if someone want to reduce their power usage and electricity bill. That way you also save money on the card itself since they are usually cheaper and you probably don't need to undervolt it as much, if at all

[@randomname2914]

I upgraded to a 4070ti from a 2080, double the performance and also undervolts down to 140 watts. But in some CPU heavy games only 40-60 watts, where my 2080 was on 120. As well as less on the desktop. So I'm actually saving much energy with a 4070ti.

[@GerbenVanErkelens]

Ah yes interesting to see. Have to dive into the undervolt a bit more myself too. So far i just press the undervolt button in the software 😅

[@Allblaster]

Just want I wanted to see with this card, thank you so much :)

[@TechTesters]

You’re welcome 😊

[@sweeleangloh]

Nice!👍 but there is "luck factor" involved right, as in how much a card can undervolt and still runs stable, like overclocking🤔

[@TechTesters]

Yeah definitely. One of the reasons we didn't spend too much time getting the perfect undervolt. Hopefully most people can get at least a similar-ish result in terms of fps/watt, and anyone who spends the time can get even better results.

[@BMGGHOST]

Love the content. I personally undervolt with an overclock.

[@leovanlierop4580]

Great video, thanks. I now undervolted my 4060 Ti for the first time, here's my steps. In Cyberpunk I use 1080p Ultra+RT settings, using 160 watts. Limit the FPS at 60, using 133 watts. Set RayTracing to medium and DLSS from quality to balanced, using 115 watts. Undervolted my card using MSI Afterburner, flatten the curve to 2600MHz, power to 90%, using 98 watts. Further setting DLSS to performance, using 88 watts (optional). From appearance this looks almost the same as the 160 watts usage almost halving it!

[@Neversettle0o]

Wow, interesting content. Thank you!

[@TechTesters]

Hope it helped :)

[@cbats1888]

Nice video! I did the same with my Asus Arez Strix Vega56 except for that one you need to adjust P-states and not just the main slider. It went from a consumption of around 240watts to 145watts playing RDR2. However I do have one remark/question. For my Vega56 card, after undervolting and adjusting the frequencies, you for sure do not reduce the power limit, which you did do for this 7800xt. Have you also tested the results after changing the voltages and maybe frequencies a little without reducing the power limit? It could potentially provide better results

[@TechTesters]

Thanks! And there is definitely room for optimization in there, like I said it was a pretty quick uv. Still took several hours before we hit ~200W while remaining stable, but it definitely went easier with the PL at 90% than 100%.

It really depends on the card. My goal here was to try and match the Nvidia power draw, I'd suggest looking up some more guide-style videos to find more specific OC/UV advice!

[@ofon2000]

By the way, could you also do a video on how to reduce idle and video playback (youtube browsing etc etc) on radeon GPUs? My 7800 xt was idling around 12 watts (fine) but the video playback was around 40 watts, sometimes shooting up to 70 with adrenaline open when I was merely moving the mouse around a bit. Kinda curious if it's possible to move the power draw on idle down to like 20 while watching youtube like is possible on my 3060 ti. I was reading that there are some settings to turn off in Radeon Adrenaline under ReLive or somethin that turns off desktop recording to reduce idle power draw, but I wasn't able to find it as the official guide from AMD was from 2021 or so before the software had changed.

[@Ivyticrea]

Maybe and chill is something for you. It caps the frame rate to a chosen amount when you’re not moving your mouse. I found it annoying in gaming tho

[@ofon2000]

@@Ivyticrea I actually had radeon chill on...I couldn't get the card to go below 40 when watching youtube. On my 3060 ti it's only like 15 but spikes up to 40 occasionally when I have a livechat open or running my cursor over the video

[@Venlorz]

well, i'd like to know how many ave. watts on those games too

[@robertwilliam5527]

In early days AMD GPU's tend to gain performance with undervolting, but lately I see this behavior on my 6900XT as well where it underclocks itself depending on the voltage. Excellent and informative video, keep up the great work.

[@zet7914]

ALL GPU's gain performance with undervolting if they are Power limited

hey i have ryzen 7 5800X3D and 550w psu seasonic gold i want to buy 7800xt should i change psu or not and what model of gpu you recommande ty

[@TechTesters]

Assuming you don't run a lot of other hardware I expect it will hold up fine. I've ran a 2080 Ti off a 550 Watt Seasonic Focus PSU years ago for a giggle. I mean you can give it a try at least, otherwise upgrade to a 650 or 750 w.

[@fallinginthed33p]

Those are strange twmperature numbers and I'm wondering if the undervolt affects sensor figures. The card uses 40% less power but GPU and RAM run slightly warmer.

[@TechTesters]

Not really, notice how much quieter it is. 39 -> 32 dB(A) is a huge drop.

[@andremarquardt8687]

Have the Gigabyte as well. At first i was trying to get it to ~200W as well, but in the end i just adjusted the fan curve and reduced the voltage. Up to 285W (standard power limit) it is quiet enough for me, so why limit it. Also in Starfield it's not going over 215w anyways.

[@TechTesters]

Probably running into a CPU bottleneck in Starfield :D

[@HighIgnition]

did you tried the under-volt wizard that comes with the Radeon software? does it do any changes?

@@TechTesters indeed but only to know if that wizards helps at all?, maybe as an starting point to fine tune the settings?

The 7700XT is also heavily overclockable, I'd really like to know how well it compares to other cards with an undervolt and OC and how efficient it can get.

[@Ladioz]

I think it wont use too much power in 1080, with RT off and FSR on

[@Brype4000]

yeah I've got one now and I got the core @3000Mhz ~ 1.05V and mem @ 2600Mhz & fast timings. It's using max 200W, haven't compared the game results to non OC yet.

[@Ladioz]

@@Brype4000 Thats why I like the Sapphire Pulse because it doesnt have a boost OC that comes with the card... it also uses 15-25W less power than the 3 fan cards.. its almost like a plug and play card. I know 2 fan cards arent the most attractive for gaming performance, but it seems like the 7700 XT series are really good at low temps, which is weird because they are very power demanding. However, ill say it again, its interesting how the Sapphire pulse uses the least amount of power from all brands yet also keeping temps always below 63 degrees in intense gaming

[@RobBCactive]

I happily undervolt and am willing to lower the freq limit to run stabily at lower volts for most usage, then use a game profile to crank the card up in a game specific profile where high performance is needed, it's really easy to do in Adrenaline. What I've seen is the 1% lows tend to be hit disproportionately in heavy gfx games, but my card needs frequency limiting to run stably at lower voltages and have max power reduction. The games I play the most are strategy and don't need super high fps so I really can enjoy running cooler in summer to reduce noise, while having other setttings for a fast paced game.

[@VADemon]

if 1% low is a problem, don't limit the power budget and only work with frequencies/voltage. imho

[@RobBCactive]

@@VADemon the power budget isn't used, the GPU would perhaps like to boost higher in parts with low utilisation but if it's not stable that isn't usable. This is perhaps the silicon lottery in action, where the volts are required to hit the highest frequencies.

[@VADemon]

@@RobBCactive Have you seen igorslab's oscilloscope graphs of power consumption? Easily +50W peaks for only a few milliseconds.

[@RobBCactive]

@@VADemon no but I increase the power budget by 10% not lower it (having seen the outrageous spikes Ampere had), so while I know you want to help, but you simply are jumping to a conclusion due to insufficient info. I've experimented and my real point was to remind people that 1% lows can be disproportionately worse when undervolting and that lowering the frequency might be required. Plus that per game tuning is very simple with Adrenaline software. Undervolt with small stability frequency cap can save a lot of power, but for games heavy on the GPU using a mild level of upscaling and Radeon Chill are good ideas.

[@VADemon]

@@RobBCactive thanks, that kind of experience shared is very insightful!

[@michaelpalin8953]

Just a small question about undervolting and the like: These setting are saved in the BIOS, right? Does that mean that you can undervolt in Windows and it will remain so if you switch to a Linux partition? Thanks in advance!

Thank you.

[@RussLudwig]

Thank you Nada!

[@TechTesters]

You're welcome 😊

[@elu5ive]

it seems to me that lowering voltage below a certain point makes the VRM just raise the amperage, because power consumption stays the same. that's probably unhealthy. my 7800XT "gaming OC" is running at up to 2300mhz GET from 2200mhz SET with 1077mV and the highest wattage i've ever seen in any game at any setting (including RT) was 202w. attempting to lower voltage further doesn't seem to affect consumption significantly (on my own sample that is)

My reference 7800XT only uses 198w or so out of the box, no tuning or touching the power % slider. normal?

It should use around 250w while gaming.

[@gmt1]

Thanks for this, was worried my 650W PSU couldn't handle the 7800 XT (700W is recommended). However, if I undervolt it should be just fine.

[@TechTesters]

Depends a bit on the CPU as well, but with an efficient CPU definitely.

[@SusannaSaunders]

Is it better to go for an expensive card (more than you currently need) and then under power it for power saving to achieve an acceptable cost to performance ratio or is it better to go mid-range and accept the performance hit to get the running costs down? I don't know what this triangle looks like for different GPU performance levels?

[@TechTesters]

Generally speaking "future proofing" (ie buying performance that you might use in a few years) isn't the best use of money. But GPU improvements have been pretty limited recently. I'd personally buy the card that suits your needs right now, and your expected needs in the next 2-3 years. Don't buy a GPU with the idea of having it do what you want 5-6 years from now.

Hmm idk.. seems like the undervolting could be tuned a bit better? I have a 6800 xt which I undervolted and Overclocked. I’m seeing more fps, but it’s much cooler and quieter with a significant drop in power usage. Anything more than what I have it set to starts to see a hit in performance. With my undervolt I’m getting 90-140 fps (depending where I am it’s drastic) in Baldur’s Gate 3 1440p with a 5800x3d.
