sempron 140 not power efficient ?

post #1 of 19
Thread Starter 
Hey guy after browsing a bit it look like this chip miner use and many people..

Use power like a monster

Unlock it a x2 220 just checked a x2 240 power consumption chart at the wall of 196w


and the sempron 140 is 143w at idle..


Look like worse than my fx 6300 and even 8350


i think im going to build my server based on intel... No overclocking for me sad-smiley-002.gif

I'm thinking the same thing.

 

This would mean that it's the entire system, not just the CPU.

Single core CPUs typically have a higher idle power usage than multicores because there is only one core for the OS to idle on. Under load the single core should be better though.(this is of course only when the cores in the CPUs are comparable)

They say they are looking at an "off the wall" chart. So I assume it is entire system...the actual socket draw of a semp 140 is like...40 watts or something.

Then that's the entire system, not just the CPU. The CPU is not pulling all of that. You have to factor in the rest of the system. The CPU itself is probably only pulling about 35-40W from the PSU.

 

I see a maximum of 163W at the wall there and a minimum of 139W. That's a difference of 24W.

Yeah that review shows you...the single core is higher at idle, but makes up for it when under a load. In the case of a home server...meh...you might be sitting idle quite a bit.

In the end it probably wouldn't matter a lot...for each 24/7 watt you save in the US is equal to about $1 per year. So if you can save 20 watts...you will save $20 spread over the entire year...which if you have the resources to want a home server that shouldn't be a deciding factor. Though I don't how expensive electricity is in Canada.

Yea


but looking at that my 6300 is power efficient O.o

You are comparing two very different systems.... geez. Look at the difference between idle and load of the Sempron 140: 24W. I mean, come on! It's a 45W TDP CPU!

 

Yours has a difference of 94W between idle and full load. That's 70W more. Clearly, the FX-6300 consumes a lot more power than the Sempron 140.
