Thank you so much for this video! I really appreciate all the effort you went through to benchmark the different settings. Definitely gonna be running my CPU in Boost Disabled cause I don't care about max performance.
Amazing Video! Thank you mate - rly appreciate all the effort.
Great seeing someone doing videos on power efficiency and not only raw power more watts type of videos.
Professional work 👍
Thank you! You're the only one who mentioned that we could set the Max Mhz for the CPU in windows battery settings! (newer intel CPUs cant be undervolted sad)
Exactly what i did when tinkering with a new laptop, thank you for making this, now i have a good reference if somebody asking about this
Thanks I'm glad to hear that its helpful! =)
Hi!, i own an Acer Swift X (2021 Model with Ryzen 7 5800U and the RTX 3050ti) , I've purchased it exactly for its combination of low power high efficiency CPU with a relatively powerful GPU (specially given it's stock 35+5W tdp limit). This product philosophy is very attractive and i love you have created a channel and content reviewing and comparing products with similar design philosophy, keep up the good work!.
Interesting video! I feel like this is something manufacturers should do themselves.
This is an amazing video! Thanks for putting it together.
Do you know if the CPU BOOST Disabled (or Aggressive) survives a reboot?
there! Thanks a lot for the help, I'm going to subscribe to your channel and keep up with all the videos!
Thank you glad to hear it!
best video ever
Amazing work ! Thanks alot for all the work exploring all these modes, would you be interested in doing a similar video for the the 680m integrated graphics ? Like disabling the 3050 and andervolting/overclocking the 680m ?
Would love to see something like this.
In addition, I recommend replacing the thermal paste with Honeywell PTM7950 phase-change material is more thermally conductive than the best pastes. Replace low performance thermopads with gummy thermal paste Laird 607 or Upsiren U6 Pro.
I just want to say how brilliant this video was! I picked up my laptop (6900HS version Slim 7 Pro X) and was shocked at the temps I was getting running simple games (approaching 90 degrees). Simply by switching boost off I am now running below 70 degrees. The change is so drastic and I'm grateful for all your help and in-depth breakdown on this topic!
Oh thanks so much! Very glad to hear that it helped! :)
Hi Juryy, do your slim 7 pro X have light bleed on the screen lower edge? Mine came with a little spots...
@@MrReadbosT There doesn't appear to be any light bleed on my model no, I have just tested!
@@WattPerformance Disabling the boost really makes the 6000 6nm node efficiency shine, because it didn't have any major performance drop in the Cinebech benchmark, i am so excited for the 7040 phoenix laptop to drop on 4nm, when you disable boost efficiency will be through the roof, but i wanna ask this question is it possible in your case to disable the Precision Boost Overdrive in the bios instead of windows so it could stay active in all application without relying on the OS????
how's your laptop holding up? just got mine and curious as to how it holds up
SO GOOOOOD i absolutely agree with UV and disabling boost
How about disabling completely the gpu from bios and allow cpu to use as much power needs? Does this increases the results of the benches? This would be great for normal tasks if Temps and noise is low. Can you check it?
How can I get all the options that appear to you when configuring the power plan, I have activated Processor Frequency and CPU BOOST, but only those 2 options appear.
I have a Acer V15 Gaming Laptop 4050 may I ask which setting that gives you performance and at the same time it cool down the processor?
my base clocks are 3ghz what should my minimum processor state should be?
Thank you Watt Performance for making this video. It's very in depth and easy to understand even for someone who is not very familiar with this subject like myself. I appreciate the effort and time you put into making these videos even though it can be for a very niche targeted audience. You are helping us few pro x users immensely. 💙💙💙
Thank you Manith! Very glad to hear it! =)
any update on making a 6800hs act like a 6800u?
Wow, you actually answered most questions I had regarding this topic. For now I went the disable boost route. But I'm encountering an issue that seems to only affect games :
When launching a game, the CPU automatically goes to its max "non boost"/base clock speed (3200 mhz) even at low CPU usage. I tried limiting CPU frequency and max power state in power plan settings with no success.
Could be placebo but it feels like a waste of power leading to unnecessary additional heat and noise levels, evenmore so when I'm playing light games
So my questions are :
1) Is that a normal behavior ?
2) Is it windows, bios or driver related ?
3) Is there a way to set some kind of dynamic frequency for games ?
My laptop is an HP omen 15 - r5 5600h + RTX 3060 (with my own custom UV profile) + 16gb ram
So glad to hear it! I would not fret in regards to this as power usage is key. The frequency can be listed at the base clock but if the cores are not utilized, then the power consumption will still be lower. That’s the key reason for 8 cores only consuming around 10W in game, but draws more then 2x more when using Vince bench (which makes all cores to the max)
Great video, thank you!
Any idea how to perform this changes under Linux? Thank you again
I’m afraid not but I know there is even more possibilities for Linux users. So hopefully there are some good guides for this :)
hello, awesome video! needed some help, i expanded processor power management and the maximum frequency option didnt pop up, any idea why?
Thanks! Check 7:00 in to the video and you find a how-to guide :)
Im facing a problem. If i use the shortcuts, i cant seem to enable or disable boost. Its strange because if i go to advanced power plan settings, i can see it disabled, but its actually going into boost. On the other hand If i disable boost directly from the power plan menu, it effectively turns it off as expected.
Same for me. Did you find a solution?
Thanks for trying this, reduce power consumption and get more performance? It's like magic! Are you still happy with the laptop? No quality control problems?
I’m very happy with the laptop. One issue concerning the Wi-Fi/Bluetooth card though. Currently discussing with support. Will make a video about it as soon as it’s resolved. Support can handle it but may just pay 30EUR and replace the card myself. Stay tuned :)
@@WattPerformance I received my slim 7 pro x a couple of days ago, and I noticed some light bleed in the lower edge of the screen. Like 4 or 5 little spots of difuse light, do yours have any? I don't know if I should change this unit...
@@MrReadbosT Hello, no nothing that I’ve noticed as I’ve been using it. Recommend taking a picture of it and showing the retailer you bought it from to get a suggested action. Act fast if you are still within the window for return to get this started and you can use it and figure out if this is of concern for you before it’s too late :)
Hey love the video. Quick question a little off topic. How does the Lenovo Slim 7 pro X run for general tasks such as browsing and documents? Does it stay cool? Or does it get a little warm?
It stays cool. I usually chose battery saver mode when not doing anything intensive (just fn+q) and that keeps it very cool and quiet with great performance
@@WattPerformance thanks!!
@@WattPerformance would you say that with battery saver mode there's is zero difference in responsiveness when doing web browsing or simple office word writing?
@@maxolina yes I would
@@WattPerformance I know this sounds stupid - but are ‘battery saver’ and ‘intelligent cooling’ modes only available when running off the battery? In other words, do you have any built in options to reduce power and heat etc when plugged in - or is it just what you’ve shown in this video eg disabling boost? I’m getting the version without the 3050 but I’d like to keep it as quiet as possible even when plugged into my docking station for work.
In power options, I am not seeing an option for 'processor performance boost mode'. I have an Intel Core i7-13620H, will doing what your video suggests still work for my processor? Thanks!
Only AMD can Do that
When I disabled boost and enabled it again...the boost feature wouldn't turn back on. I stressed the CPU and can see that speed never went above the base clock. Does it it time for it to readjust and turn back on? I restarted and it still wouldn't work. I had to reset windows and it finally went back to boost working. Any thoughts?
Do check enabling/disabling battery boost mode separately from plugged in (ie try aggressive plugged in and switch between battery disabled & aggressive). Weird setup for this laptop but that usually fixes it back. Should be no need for reset or reboot
@@WattPerformance Thanks. I also noticed that when you go to settings and power mode and you have three options: bettery battery balance or better performance, that this affects the cpu utilization over Lenovo advantage. Also my pro x only has a balanced mode in the actual power options.
Question, if you don’t mind: what impact might disabling boost have on fps on the version of this machine without the 3050?
I found myself getting nearly the performance I wanted in the Football Manager match engine in battery saver, but the machine getting hotter than i’d like with intelligent cooling on. Nothing major - just a bit warm and noisy for the sofa.
Any suggestions welcome for squeezing more juice out of battery saver mode (plugged in) would be great - or in making intelligent cooling more, er, cool and quiet!
Thanks - and thanks for these videos!
Hey! If you have the laptop, do try to disable boost when running on the iGPU and check what FPS you are getting before/after. The CPU boost should not affect the iGPU negatively but there are also no other ways of adjusting the iGPU just in WIndows (apart from the overall power settings). Using the Ryzen Tuner (mentioned in the video), you are able to change the TDP for the iGPU as well if you wish to opt for sacrificing some performance to reduce sound :)
@@WattPerformance Hi again, I just wanted to give you the results of my tests:
I was aiming for 60fps in the Football Manager match engine with high settings (with my iGPU model). Intelligent Cooling could pull this off no problem - but it was a bit too hot and noisy for my liking. HWinfo now tells me that it pulls about 34W doing this. Battery Saver, at a mere 15W, gets you to around 55fps, and the CPU stays a cool 54 degrees.
Disabling boost seemed to have no discernable effect.
The two alternate settings I created with the Tuning Utility were at 20W and 25W. Neither, bridged that gap up to 60fps, even though the temperature increased by about 5 degrees with each step (and the fan noise a touch with it). I got a couple of extra fps but no more. And the laptop crashed a couple of times with such profiles applied.
So now I know - for my case, it doesn't get any better than generic 'battery saver' for silent cool play while the missus is next to me on the sofa watching TV, or intelligent cooling if I want to up the graphics at the expense of a warm lap and having to turn the TV up too!
All the best!
@@Vlowman Interesting! The CPU Boost can be tricky in terms of the settings as I've found that sometimes battery needs to be in aggressive and plugged in needs to be disabled for it to work while plugged in. So do confirm via HWMonitor for example that the CPU boost is disabled (max boost frequency of 3200MHz) when you play (if you havent done so already), As i believe that IntCool+No Boost should likely come close to solve your issue. Try if you have the stamina and let me know if you can confirm that CPU boost is disabled :)
@@WattPerformance Which of the many items listed with a MHz value in HMWin is the main frequency that we're looking for?
Hi Watt! is windows processor performance boost mode disabled good for iGPUs? (not discrete gpus)
I haven’t tested it but might be worth trying out. It might prove beneficial if windows is able to separate cpu package power from ipgu package power. Either test it with a game remaining static monitoring fps difference. Or download Hwinfo and look at iGpu package power with the setting enabled/disabled to see if it drops when it is enabled :) good question and good huntin’!
How would you compare the yoga to the T14s?
I would say that the primary differentiatior is the build quality, build materials and screen where the Yoga has the lead, but where T14 is more business oriented and likely has better battery performance
would this method work same for intel version?
Yes, but you can also use throttlestop to undervolt and manually tune your boost limit with Intel which give you further opportunities to fine tune the performance. :)
How do you adjust cpu tdp in Linux?
Afraid thats not a ecosystem I'm familiar with to that extent
just found this channel from oakenglass. and man, i love content creators like this. like a treasure only few people knows
Thank you for the kind words!
It is possible to do that with Intel version?
Yes both disabling boost as well as undervolting are options för the Intel version.
When setting a cpu temp limit, does that limits the tdp as well?
The temp limit is Held by boosting as much as possible until the temp limit is reached. So it can start of with a higher tdp which is then decreased as to not increase the temp above the set limit
@@WattPerformance is it possible that such apps to control CPU temp and tdp make games crash freeze etc sometimes?
@@petarstoev4848 yes the current versions has not been stable in my experience which is why I defaulted to disabling boost which is 100% stable for me. I mention this in the video I believe :)
how to decide how much watts/tdp to set? Ryzen 5600H laptop
Comes in many ways down to personal preference, in many instances you selldom require more than ~20-25W as that is enough to sustain single core maximum boost for the feeling of a quick and agile OS and apps, more if you are running computational tasks or running a CPU intensive game. Personaly, I only use enable/disable CPU boost where I always have CPU boost disabled unless I'm either running video editing software or am running CPU-intensive games such as Hogwarts legacy. Turn it off or turn down the TDP or wattage until you notice that it performs below expectations (you have paid for the speed to dont want to remove it). I very much prefer a 3-4% reduction in speed and never having to hear the fans turn on when doing simple tasks =)
@@WattPerformance I just set a 65 temp limit(cpu) without removing the cpu boost and touching the tdp. Is this a solution or are there better ones to achieve this?
sorry, what is uv (oc) means and how do you use it?
Sorry I’m lagging behind on this video. Hope to get it done this week. Undervolting and overclocking means that you change the settings so that the GPU clocks higher whilst using less voltage which boost performance and reduce power draw.
@@WattPerformance hey, any update on when the videos dropping?
@@ibrahimsoualhi7735 yes! Thank you for following up! Away on vacation until this weekend but after that I aim to release it shortly. So within 10 days maximum!
I noticed that if I have max freq set to 3300 and intelligent cooling it doesn't boost and seems to not surpass that number. You said that didn't work for you? With all my testing using cpuZ or Geekbench and cinebench it stops at the freq I set it on and doesn't boost.
In windows applications and cinebench it works for me as well, but if you enter a game it will change the settings and boost to 4.7GHz. I assume this is due to their adaptive solution so it manually changes the settings
none of those options can be seen in lenovo legion 5 pro r7 5800h 3060
Have you tried enabling the options using Reg edit as instructed in the video? They are never visible as default :)
@@WattPerformance i m doing it right now
yeah make sense, spend 1k euro on laptop like 3060 or 4050, then cut perf for 40% cause u have less noise literaly 200iq bullshti
?
The video shows how to reduce noise and heat AND increase performance while gaming. If you prefer running hotter with worse performance then just keep stock settings at all time. I adapt based on my use case :)
@@WattPerformance how it's worse performance when I turn off boost in battery or I'm missing something?
In a huge amount of cases with gaming, the CPU will boost to higher power-levels without positively impacting performance, so the increased power goes to waste, and if you have a dedicated GPU as well (which in this case is true), then the CPU-power will steal the potential for the GPU to boost higher due to this. For these reasons the majority of games will perform better and draw less energy if boost is disabled. There are some instances where this is not true, especially games relying on single core clock speeds or where the GPU-bottleneck does not exist. For example Counterstrike with low graphic settings and +150-200 FPS will likely benefit from boost enabled. @@justrose4905 For productivity, the boost is beneficial if you are running computation heavy applications or if you actually notice as perceptible decrease in speed, in which case you should have it enabled. Apart from that the CPU will often boost to the headroom it is allowed to boost to, even though it is not required.
As always it depends on your needs and use-cases, but disabling the boost is very easy and often a good albeit blunt way of doing it. The best way is to limit the total allowed TDP so the CPU is allowed to boost single core up to max but cap the total package TDP for all cores, but that is more on a per laptop basis atm as UXTU and other applications are not stable enough to allow for this.
