Modern computers /too/ power efficient?

Yes it does just like on laptops:

One of the first things you will notice going to the High Performance from Balanced or Energy Economy is that the CPU will keep running on max core clock regardless the load instead of scaling as demand comes, though this consumes more power it doesn't stress the CPU.

For what it's worth I've also not ever noticed a performance difference in day to day tasks allowing the CPU to scale up and down as needed. I used to for years lock all machines at 100% clock using the performance setting but recently i've switched back to allowing the adjustment and haven't noticed a performance hit. Personally I enjoy reducing my power bill as much as possible, that means it's that much sooner I can buy the next piece of hardware.

I have not noticed meaningful changes either, but then again I do not mind the bill and it is not stopping me from buying hardware

 

You could say it gives somewhat placebo effect too haha

Ah.  Thank you for showing me.  

 

I'll have to take a look on my computer later because I don't understand that language.  I assume that's either Portuguese (I had to look up Brazil's official language) or Spanish?

Portuguese, I graduated in translations and interpretations and I do professional translation from english to portuguese and vice versa for a living. I have public faith to translate official documents and such for notary offices, registry offices, courts etc... Great job if you ask me I managed to get funds for my PC and get into a second college which I start monday; information systems I will finally become a programmer like I always wanted to [:

 

I did not think the language would be much of an issue hahaha here you go in english, my bad ^^

if you just search POWER OPTIONS in the start menu search box it will take you to the screen he has there, basically Balanced allows the processor to ramp up and down between 5% and 100% where Performance locks the core clock at 100%, (it also has other settings, but thats the big one), you can also set Performance then go into the advanced setting and change the "minimum processor state" if you wanted to allow it to ramp down, really the different presets are just profiles that auto switch kind of like switching between picture settings on a TV, all the settings can be set manually, switching between performance and balanced (or any other preset) just makes it quicker to change, personally I set it to performance then go advanced, set the "turn off hard drive" to NEVER and then change the minimum processor state to 5% (the lowest setting)

That's great you're furthering your education.  Good luck with your new degree.  ?

 

 

Sorry.  It wasn't that much of an issue.  I was able to recognize the screen as being similar to the power management but not read what the options said.

I'm on my iPad atm so I can take a look later. 

 

Does the performance setting do other things besides lock the processor to 100%?

 

I mean if you set it to performance and then allow the CPU to ramp down as low as 5% doesn't that negate the benefit?

Thank you ^^

About the energy setting, it is like we have been saying the changes are not going to be that much noticeable, if you have a high end processor you should not worry much but say you got an i3 setting to the balance mode might occasionally cause certain issue such as windows telling the processor that google chrome application of yours only needs 2ghz to run fine and then you open a ton of tabs and it doesn't adjust correctly to a higher like 2,6ghz speed and you get that annoying program not responding lag here and there.

 

I would just put high performance because to be honest I do not think the price differences down the line when the bill gets to your door are worth somehow limiting your PC from reaching its full capacity.

Higher power usage for a chip only allows for more performance because it allows higher clockspeeds . If a chip can't go beyond a certain frequency, give it more voltage (thus, more power) and it'll be able to run faster, as long as the heat is dissipated so the chip doesn't burn and die.

 

Intel's Netburst (Pentium 4) went with that idea, they designed the chip specifically to allow high operating frequencies and all it did was vividly demonstrate to the world the concept of diminishing returns. At a certain point, every tiny increase in operating frequency requires monstrous extra amounts of power that quickly turn ridiculous compared to the actual speed gained.

 

I think it is safe to assume chip makers have learned that lesson and are now smart enough to pick that point beyond which power use shoots up while speed returns dwindle and they apply this knowledge to their chips.

 

Efficiently using extra power for more performance would then be done by using multiple chips, each of which running at an efficient clock speed and indeed that's what is beeing done. You can run multiple GPU's in SLI and buy motherboards that allow you to fit multiple CPU's. That way you can still build a 1000+ watt beast that somewhat makes sense versus burning 1000 watts trying to run that single chip a few hundred Mhz faster.

meanwhile nvidia's 10xx series..

im stuck at 1.06v on my 1070, and its hitting 125% power limit, but hey its getting 2100mhz core

(let us do more power limit, 1.06v is fucking nothing)

You're welcome.  

 

I have a 6700K so I might not have to worry about that like someone with an i3 like your example but I'll keep it in mind.  ?

there are other settings, like what happens when you close the lid (on a laptop, like it can automatically put the computer to sleep when you close the lid or shutdown or do nothing) and settings for WIFI power cut off and what happens when you press the power button or sleep buttons, just a bunch of things like that, but as long as you don't let the computer put the hard drive to sleep none of the other settings really effect the overall performance.

Ah.  Ok.  Does it affect an HDD or SSD much if it never turns off while the computer is on?

yes but the things you would run would need 10080 class performance lol

don't know if there would be any real difference with an SSD, allow a HDD to shutoff means having to wait for the drive to spin back up when you go to access data off it which would be a performance hit, I know the External HDD I have attached to my Router (for NAS functionality) goes to sleep and it's several seconds (like 5-10) for it to spool back up so I can access data on it..
