PBO vs OC ECO

[Zarginnia]

whats the difference between the PBO Eco and the Overclocking Eco?
Wich is the best option to use?
Have 5800x

The eco option is better because you will boost higher. The downside is if your CPU ever needs to run every CPU thread to it's maximum, you might slightly lose core speed.

Nothing will really max out your 5800x, especially every CPU thread, no way. So you may safely run in eco mode and enjoy more boosting opportunities, which games love more than anything else.

You mean the OC Eco right?

Eco mode is technically an overclock unfortunately yes because you are effectively running your CPU outside of it's original design. That's why AMD makes you agree.

No, its not.
You know that there is a difference between overclocking and undervolting, right ?

ECO-Mode will limit your TDP down from 105W to 65W and youll lose a couple % on SIngleCore and a bit more on MultiCore.
5800X on Eco Mode equals a 5700X.

False. What makes you think that ?

Literally nothing ? Kind of a bold statement, isnt it ?
My 5950X bottlenecks my 690XTXH even on 1440p in most of my games (MSFS2020, WD Legion, Cyberpunk, etc.), let alone a 5800X.........

edit:
@OP
Try to erase everything which has been said above by hardwaredude.

ECO = less power consumption = less heat = lower core clock = less FPS
PBO = same power consumption as stock settings = higher core clock = more heat = more FPS

Given youre being bottlenecked by your CPU. Otherwise, it wouldnt make any sense to run the CPU other than on ECO mode.

edit II : And there is no such thing as PBO ECO. There is Eco and there is PBO. Two different things.

You're right on most of it, but I think the first part might depend, no? I definitely noticed a reported increase on my 3700X though.

With PBO off, it limits itself to 88W (I have a 65W TDP CPU), and with PBO on, it goes to between 100W and 120W/125W or so. The 105W TDP CPUs will be around the low 140W nominally IIRC, so it might be possible that the 105W octo-cores don't increase power consumption as much as they are already there nominally, I can't say. But on my x700 series, which is the same thing as the 105W octo cores but limited to 65W (and thus a bit less performance), there's a rather substantial increase in power consumption (and a bit of one with heat) with PBO on.

Not sure how it'll work on OP's 5600 given there is no 105W hex core within AMD's Ryzen family to my knowledge.

It's also possible I'm confusing PBO with something else? But I thought it was PBO that changed the behavior.

[Schrute_Farms_B&B]

Hey Illusion. Hope youre doing fine.

OP owns a 5800X, not a 5600X.
5800X TDP = 142w PPT 95A TDC 140A EDC

These are the limits in terms of power consumption. It doesnt matter if you use PBO or not, the limits are just the same.

I think the difference on your 3700X might be caused by pre-settings, determined by your motherboard. I had Gigabyte&Asus boards, which would use insane/weird TDP/TDC/EDC values for Precision Boost Overdrive.
edit:
Thats why I always suggest to use PBO advanced options where one can manually adjust the limits.

[Illusion of Progress]

Oh, no idea why I was thinking it was a 5600X, might have been confused with another thread. thanks for the correction.

With a 5800X, PBO might not change power consumption much since it's already a 105W rated CPU. It seemed to make a rather big difference on my 3700X though, as long as I'm not mistaken and PBO was the only setting I changed off between the comparison (I think it was). The x700s are just lower TDP variants of the x800s, so my thinking is you may see higher power consumption on the x700s in particular with PBO on compared to off, but it's just a guess.

The insanely high values for some of those parameters I saw too (Asus board) but I thought even with just PBO on but the other setting disabled, I was still seeing power draw of 120W-ish, compared to 88W with PBO disabled. Maybe I'm mistaken and I disabled both but I think even just PBO was giving my higher power draw/temperatures. I'd have to check to be sure.

ECO Mode is an undervolting feature, PBO is an overclocking feature. The notion that ECO Mode increases performance is utter rubbish because in actual testing, you lose slightly in single-core performance and much more in multi-core as you're heavily reducing the amount of power the CPU is allowed to draw. Anyone that claims it does hasn't the slightest clue.

105W CPUs are reduced to 65W, 65W CPUs are reduced to 45W.

The purpose of ECO Mode is to reduce power consumption for the sake of better thermals or for a more "green" system use case.

And there is no such thing as PBO ECO. There is Eco and there is PBO. Two different things.

When going to PBO i can choose different settings for example PCO-Eco 45w/65w/90w or something like that and then also have Eco mode wich sets it to 65w did notice that when i changed the PBO to eco 65w and went to the other eco mode it said 45w. so im a little confused. Do have a EK-AIO 280 D-RGB so it should work without fiddeling with cpu in bios just wanted to change so its more like a 5700x than 5800x wich is hotter. but maybe its not worth it? Stock 5800x when idle it goes between 27-31c so i guess it works as intended but when doing something like watch youtube or just opening a website it can spike to 55c and then down again to idle temps so i thought maybe it could help to change to eco.

@Zarginnia
Temps are toally fine. This hot-head can go up to 90C before thermal throttle starts to kick in.
So its totally up to your needs&preferences which one you want to use.

If you feel youre being bottlenecked by your CPU, use PBO and PBO scalar to get a higher boost clock.
If youre already at 100% GPU workload in almost every game, you might want to try ECO mode for lower temps&power consumption.

You can also manually undervolt your CPU which will rrsult in lower temps and higher boost clocks. Take a look here for starters.

It might take some time but it s worth it. Ive been able to boost a 5800X up to 5,1Ghz on SIngleCore with a PBO scalar of +200Mhz and a TDP of 100W.
It may depend on the quality of your chip, but CurveOptimizer should even work with the worst chips.

Ok thanks. well the biggest "problem" is wrong word but irritation i guess is that the AIO is loud, my wraith prism was more quiet, the AIO ramps up and down and i have tried to fix that in the fans settings in bios but no luck, it still ramps up and down when doing something there was somone in another thread that said change from CPU to AIO water temp but i dont have that option. This is i guess the only reason im looking to change to eco since its not as hot and the AIO fans wont ramp up and down as much.

[Schrute_Farms_B&B]

So the problem isnt rly the heat or power consumption, but the noise ?
Didnt expected that. You should have said something. ^^

This shouldnt be a problem at all with an AIO. it makes you wonder what exactly makes your fan to ramp up so hard.
May I ask which AIO model youre using ? Did it come with extra software ? Something like NZXT Cam ?

You need to manually set the fan-curve. No other way around it. Going into ECO mode, just kind of veils the issue but doesnt solve it and comes with a cost of lower CPU clocks.

[Zarginnia]

EK-AIO 280 D-RGB no extra software what i know of.
Did change the curve again for the 12315414221421 time and its a little better than before but now its a bit hotter.

[Schrute_Farms_B&B]

Thats a nice and fancy AIO with 4x140mm Radiators.(Push&Pull). You shouldnt have any noise/heat issues at all.
So youre saying you cant change the RPM for your AIO fans in BIOS ?

Whats exactly the issue ? Doesnt it save or does it override the settings ?

2x140 fans, well the problem is the ramp up of the fans on the radiator tho i kinda minimized the irritation now. the issue is that its louder than my wraith prism that i had before but that was with 3700x. so the reason for all the eco talk was that if i could lower the temps the fans would not ramp up and down to maintain the heat as well the fan curve wich i think is ok atm but now the cpu is a little hotter. actually tried the PBO eco i was talking about before but when i ran cyberpunk i heard a screeching noise from the cpu, i guess it pulled more watt than it needed or something? i dunno im to techhead so to say.
