GPU usage on youtube

[Mikey89]

Hi

 

So just out of curiosity wanted to ask.

 

How much should the GPU usage be when watching videos on youtube ?

 

I was watching some videos earlier and noticed that GPU usage was 25-35% when doing that in Firefox.

 

GPU is an RTX 4060 - is that normal, isn't it a bit too high ?

That's normal with HW decoding

Hardware decoding. Meaning YouTube is using your GPU (which has dedicated hardware to decode a video stream) to do the video decoding, rather than the CPU, since it is faster and more energy efficient.

But isn't 30% too high i mean considering it's only youtube ?

 

And i just noticed now, it was set to 720p - it wasn't even at 1080p.

30% usage doesn't necessarily mean it's using 30% of all available GPU resources, but rather only 30% of it's decoding capabilities in this case. GPU usage isn't as straightforward a measure as CPU usage.

 

While video resolution is a factor, you also need to consider the codec that's being used. If they are using good compression to save on bandwidth, that typically also means the GPU has to do more work to decompress it again. I have no reference to go by to determine if 30% should be considered too high. You could try disabling hardware acceleration in Firefox and then check how much CPU resources are being used instead to get a feel for how much faster/efficient the GPU is.

Even for my 3080, watching Youtube takes about 18% utilization

Also this is not quite accurate data but good enough.

@Supersonicwolfe

 

I'm noticing in your screenshot the GPU temp is 41'C.

 

Does your 3080 have like a 0 db feature where the fans only kick in at higher temps ?

Oh yes, they ain't spinning.

Oh many thanks for the screenshot !!

 

My ASUS DUAL RTX 4060 also does that and i get the EXACT same temps 40-41'C when they're not spinning.

The thing is, most coolers are tuned to have a floor of 40C, and below that the heat pipes aren't really doing anything.

How they do it is through lowering pressure in heat pipe to make the liquid inside have a lower phase change temperature (for example, water at sea level boil at100C phase change to vapor, at high elevations would be lower  than 60C). Water condense at cooler side of the heat pipe at 40/50C, and evaporate at the hotter side 70/80C.

So spinning fans below that really does nothing if the heat pipes aren't really conducting heat out.

 

If they tuned the heat pipes temps to even lower temperature, it will risk the hot side also reach vapor temperature. The heat pipe will no longer work as everywhere in the heat pipe is vapor, no condensing, no thermal conduction though vaporization.

 

Besides, Semiconductors today can do 90 for long periods so it's not a bit problem (Just a few years ago it was 80...70... just look at older CPU specifications, TjMax is only like 75C or something)

Well to be fair like 10 years ago GPUs could take the heat without that many issues - they could take up to 90'C and even more and still have no damage to them.

 

I feel like in the past 5-7 years though the maximum temperatures always put out by nvidia for their cards has lowered compared to previous generations of graphics cards.

 

Like before the max would be around 100-105'C and now in the pas 5-7 years it's been reduced to 90-95'C.

Nvidia will drop clocks when you hit 83*c now (their temp limits, separate from manufacturers fan tempreture curves) 83*c and Nvidia go hand in hand,..it's their temp limit of recent generations across multiple products. The blower style GPU's mostly sit at 83*c all day under load with reduced clockspeeds than AIB models.
Just the nature of GPU boost that Nvidia use, with a few variables at play like Temps/Power/Fanspeed

 

My 2080Ti uses 20-25% give or take watching 1440p YT

Hello

 

So i noticed with GeForce Experience that my RTX 4060 clock goes from minimum to max when i watch clips on YouTube at 1080p.

 

And the GPU temp is at 46'C.

 

If I watch them at 720p it stays at 40'C and the clock stays at minimum.

 

Is this normal ??

 

I'm kinda scared something might be wrong the GPU.

 

Would appreciate some help - this is kinda stressing me out.

Basically what @Levent is saying. It's totally normal. If you're youtube video is stuttering then you should restart your computer/close your browser. The clock up/down happens all the time

Dude trust me i'm telling you it didn't do this before.

 

I've been monitoring it since I bought it and keep GeForce Experience like 90% open.

 

It stayed at 40-41'C in YouTube not 46'C.

But it wasn't doing this before, I monitor all the time.

 

Always stays at 40-41'C and the clock never jumped up and down before on YouTube.

Is the footage stuttering? If not then there isn't a problem

Ok, the talk of GPU "usage" is often misunderstood. That metric, regardless if its HWiNFO, Afterburner or just Task Manager, relies heavily on the Clockspeed stat. 

 

You may see "35% GPU usage" in task manager but the GPU is at its idle clockspeed. That same action may result in 1-2% "GPU usage" if you enable maximum performance mode for the GPU which locks the clockspeed at its base.

It's not stuttering but something else I noticed.

 

I watched like 10 minutes of AngryJoe's video and it stayed at 39'C with the clock at minimum.

 

Then I watched some of FightinCowboy's Witcher 3 gameplay for 10 minutes and the clock speed went up and down and temp was 46'C.

 

What is happening ??

 

Fuck it's scaring the crap out of me.
