low tdp cpu(ill keep the 6600k) question now is about low wat gpu with 3x 1440p monitors...

[thrasher_565]

i was wondering what the lowest tdp desktop cpu with the best performance is? and what best performance tdp gpu is? ill (keep my 6600k)

 

ok so the question is now what low wat gpu that can do 3 monitors running at 2560 x 1140 at 170hrz with dp or can do 120 with hdmi.

 

gpu atm is gtx 1080 winforce

 

monitor 3x gigabite m270

why are you wondering this? 

 

is it power costs, thermals for small form factor...

 

An intel NUC would probably be the way to go tbh if you are looking at best performance/watt

just was thinking on building a low wat pc to save power but still be able to play some games. i dont play aaa games any more.

While not the best, per se, I always use 65 watt TDP CPUs to get a nice, even balance of performance and energy usage. All of my most recently built systems were Ryzen 1600, 2600, 3700x, and 5600, respectively. They're affordable, easy to cool, and do what I need without being overkill.

[Electronics Wizardy]

Most modern cpus llow for adjusting the tdp or power consumption. I wouldn't buy a low tdp cpu, just limit a normal cpu

 

Depending on how much performance you need ryzen 7000 and 13th gen are pretty efficent.

Under low loads modern cpus will idle at pretty low power, so Id just get a lower in chip, like a i3 12100/12400 or 6 core ryzen.

hmm i have a 6600k atm im guessing the newest cpus with the lower nm will be the best?

I mean like. Get a laptop.

 

No joke you can have all you need in a device that cant use over 120w od power no matter what you do

i don't think there's a huge difference generally,  but may also depend on model etc.

 

my 3600 used like 110w or more (which surprised me and id need to look it up to be sure, it was definitely around 100) and my 5800x3d uses 125w... sure its more but not by all that much.

yeah... i understood the question the other way around,  it's obvious to me under low load pwr consumption is negligible.

Do you need more performance? THe 6600k is a pretty low power chip, and newer ones wouldn't have a large power savings. Id keep your chip unless you need more performance.

[Needfuldoer]

I suggest getting a plug-in power meter like a Kill-a-Watt and seeing how much power your current system draws as it is. (Assuming it's otherwise fine performance-wise.)

 

It doesn't make a whole lot of sense to buy all new PC parts if it's going to take years of runtime to make up for its purchase price in electricity savings.

 

If you want a cheap, low-power web browsing appliance, get a Chromebook.

They did this in a video lol:

no dont need the proforamce i was just thinking if i did buy a faster cpu then disable cores or something to lower it even more. i no that under volting can have stability problems.

From all the power tests ive done you won't gain much power savings going to a newer desktop platform. Those systems can idle ata sub 20w, and likely much of your power consumption is parts other than the cpu.

 

How much power rae you using now? Whats your full system specs?

 

If you want a signifanat power savings you will need to go to the low power class of cpus with a laptop or m1 mac mini or simmilar.

[thrasher_565]

 

[Ebony Falcon]

5950x is the most power efficient cpu to performance of all time according to gamers nexus, so u could go bios and limit that to what ever power u desire and it will perform the best 

 

limit it to 60w it will be the best performing cpu you can get at 60w ect

atm just the tower no monitors at idle is 95w ish with a gtx 1080. i do have a rtx 3090 i will be using and an x299 witch is the opasit of power savings but that will be the gaming pc so i guess i dont need much for just a browsing pc...

What are the rest of the specs? Drives? PSU? Cooling? That can all all up pretty quickly.

 

That 1080 can chew up a reasonble amount of power at idle, esp with 2 displays. Id take it out and try using the igpu to see how much power is saved. Id guess a lot of that power is the gpu.

[Needfuldoer]

If you want to save some power on that PC for free, and you're not going to use it for gaming, just yank the 1080 and use the integrated graphics.

 

I still think buying newer desktop PC parts in pursuit of power efficiency is a waste of money. Even if you cut your idle power consumption in half, that's only 40 watts. Extrapolate that out with your cost of electricity in kilowatt-hours and you're probably looking at years of run time before you break even. If you want efficient, get a laptop or a Chromebox.

ya probly right say a 65w cpu so rest is gpu.

psu corsair something... no other fans plugged in... just the 2 on the d15 with the low power resister. ssd

That 65w is only under max load. Its probably 5-10w at idle. 

 

You can get a good estimate of power usage using apps like hwinfo.

Speaking on purely energy consumption, sure, but that's a terribly wasteful idea financially. Spending extra on a better binned, higher performing CPU and artificially limiting it is just silly. That's money you could have spent elsewhere.

It depends heavily on BIOS settings too. A stock 65 watt ryzen CPU (from most generations) with no PBO or OC will draw right around 80 Watts. Once you start enabling things like PBO that all goes out the window. For reference, I also always run my CPUs bone-stock with stock(ish) coolers in small cases, so never have PBO enabled to save on thermals.
