7950x idle question

[diango]

Ryzen 7950x doubts.
I have seen a few posts/sites where people complain about high power consumption of 80-100W in idle or very low load single thread like an open browser.

Can anyone who has such a CPU tell me what it looks like in practice, e.g. playing a video on yt in the browser, what is the power consumption?
It does not matter if you are overclocked or not, just play a yt video and read the hwinfo wattage.

PS. I don't know if this is a good thread, I haven't seen a CPU related thread.

Playing a video is not a low load and shouldnt be considered Idle.

Youtube videos are played on your graphics card, not your processor, unless you have hardware acceleration disabled in your browser for some reason.

 

[Vya Domus]

There is no way a 7950X is going to draw 80-100W in idle or playing videos.

its been a while but i seem to remember my 7950x idling at around 70-80w.
also depends on where you are looking, hwinfo shows total package power (Cores, I/O die, etc.)
Radeon Adrenalin dashboard only shows core power it seems, so its MUCH lower.

- Use edge.
- Clear browser cache, cookies and everything else.
- Check if hardware acceleration is working.

Browsers are by no means ST applications, modern ones open numerous sub-processes precisely to distribute the load across multiple cores. Certain polluted websites can indeed place high load on the CPU

I can only speak for the 7950X3D, but at idle at the desktop with power plan at balanced and default settings, Package Power is 30-35W via Hwinfo. Normal desktop stuff, browsing, somewhere in the 40-60W range if memory serves, depending on what you're doing.

You're considering the highest power draw AM5 CPU - why are you concerned about power? If that's a primary factor, there's better choices to be had.

Guys, thanks for comments but I strongly preffer numbers than opinions ewentually screenshots from HWinfo or other app
of 7950x owners...thx

thx, package(real power usage) I meant looks like in little power usage Intel is about 2x times more energy effecient(Raptor)

Sounds like you might actually mean whole system wattage, not processor wattage. FWIW my 7800X3D, which is 7950X minus a CCD and plus a cache chiplet, idles at ~20W package power and 40 degC. The whole system is drawing about 100W while doing absolutely nothing, which I'm having trouble tracking down with my thermal cam MIA.

A processor supposedly idling at that kind of power means something is doing serious, multi-threaded work in the background.

A properly idling system will always draw less power than a system of the same generation having errant apps leeching processor time. Make sure you are comparing the same thing. Check Task Manager in Windows if unsure. A 13th/14th gen Intel would likely draw much more under the same conditions, given their focus on single core performance and...well, generosity with power provision, highlighted in the recent debacle.

Correct raptor lake uses much less power on idle due to its monolithic design.

My 14900K idles around 10w.

Not only idle, low usage also like mentioned example of playinng video in browser etc. Here also 2x savings.
Amazing work Intel there.

No. I clearly mean cpu - package include cpu, it's cache mem controller etc ,just whole processor and I mean that's not whole system or whole PC with other HW.
Package seems to be the most reliable. Anyway looks like no magic there Intel seems to be about 2x more effecient in energy saving at that field.

 

[Psychoholic]

Intel uses more power under load than AMD, AMD has higher idle power.

...it would be interesting to see how that averages out overall since PCs tend to spend alot of time idle, i know mine is idle 50% or more of the time.

 

[GerKNG]

yeah it can happen since the 7950X has such a high boost clock that low load scenarios can sit at ~ 1.5V and be very inefficient.

Youtube videos are played on your graphics card, not your processor, unless you have hardware acceleration disabled in your browser for some reason.

Hardware acceleration is disabled by default in firefox at least.

This power consumption is no idle, even you don really do anything. Maybe you should check background services and tasks.

Below its a session of 6 hours with a 12core 5900X
Idle time 1hour out of 6.
The rest is browsing, watching YT, Netflix and other.
Browser is Chrome, 2 seperate windows opened with a total of 35+ tabs, constantly opened.
At some point, Steam was downloading a game and on system tray there are over 15 icons/apps running.

Check out avg CPU power, active CPU cores, CPU usage and thread % and also CPU speed/voltage.
Total avg system power was 160W.
Windows 11, power saver mode
Everything is marked with red boxes.

Ryzen idle power is high due to IOD which has a rather constant power draw (regardless of load level). In Raphael, the IOD power figures will increase if the integrated RDNA 2 graphics are in use. 80-100W is way too high, but an up to 50 watt idle load should be expected if iGPU is enabled. Usually less, though.

I'd say, between 20-30 W is normal.

AMD Ryzen 9 7950X en Ryzen 7 7700X - Is Zen 4 pijlsnel of bloedheet?

De Ryzen 7000-processors zijn de grootste technologische stap van AMD's cpu-portfolio van de afgelopen jaren. We hebben de Ryzen 9 7950X en Ryzen 7 7700X getest.

The Ryzen 7950x is not ecological. It has high power consumption in idle compared to any modern Intel CPU.

Intel KF versions are more efficient than the K versions in idle. The gap between Ryzen and modern Intel KF CPU's in idle power consumption is rather large.

If I open 4 webpages in Firefox on OpenBSD (and bspwm) I see that the Intel 12600KF is 99.8% idle.

If I close all apps the CPU will be 99.9% or 100% idle on OpenBSD. Active RAM usage is always less than 300MB if I close all apps.

I guess idle is the most popular workload for my CPU because I mainly do web browsing, kate advanced text editor, libreoffice, okular, etc.

If I have a few tabs open in Firefox and if I let music play daemon play a track in FLAC quality, the CPU usage on the Intel 12600KF is just 0.3% in OpenBSD.

Exactly 0.3% CPU usage for two light apps running at the same time.

That is the most common workload in my case. I rarely use more than three apps at the same time.

My 7950X running default, surfing the internet, web browsing,.. average is 38W @ 5,607 and maximum is 122W @ 5,786 with multi-tabs open.

 

[dont whant to set it"']

@diango 80 to 100 Watts idle is ok, if total power.
Mine is a bit under 80Watts after power up, 5700XT card, DDR5@ stock 4800MT so the IOD is not working harder , but it is a dual rank dual sided 64GB kit of ram.

It's not hitting 80w at idle. It idles at around 30. When browsing yes, it goes up to an average of 45 and spikes up to 65w. For the exact same tasks (2 videos steaming while browsing the web) my 12900k was at 7 watts, so yeah amd chips need a bit more fat.

I can only speak for the 7950X3D, but at idle at the desktop with power plan at balanced and default settings, Package Power is 30-35W via Hwinfo. Normal desktop stuff, browsing, somewhere in the 40-60W range if memory serves, depending on what you're doing.

Yeah, your numbers on the 3d are the exact same ones on a normal 7950x too.

Just to showcase what a comparable Intel product does - 2 videos streaming (youtube + twitch) while on a discord call and browsing the web, average is 7.8watts
