sempron 140 not power efficient ? - Page 2

post #11 of 19
Yep, that Sapphire HD4890 BattleStation Edition used in the review is what is sucking most of the juice at idle.Those older cards didnt have power saving features at idle. With CnC enabled on my 4.8+ ghz system, I only draw between 75 to 80 watts at idle, per my Kill-A-Watt readings smile.gif. On my old E8500 @ 3.8ghz with an 8800GT, I was drawing 110-120 watts at idle. A Kill-A-Watt unit is handy to have around the house, and it goes on sale frequently for like $17.

look down at the wall chart

It isn't so much about power savings...but about cost. That Semperon 140 and the 6300 might be fairly close in power usage in the right circumstances...but if the 6300 is sitting idle most of the time then the extra cost of building the server with it is lost. You might use about the same amount of power, but you'll have more cost in hardware.

This is why I tell people that want to start a 24/7 home server to just use whatever parts they have laying already or upgrade their main rig and re-purpose the hardware. You'd have to run the server for several years to make up for the cost of buying better power efficient hardware. If you are truly going to buying hardware to make a home server...just get the cheapest thing you can find...which the Semp 140 would probably win at. You'd probably find a used one under $20 USD.

Though having that 6300 would open up all sorts of play ground opportunities...you could have a VM host running a dozen machines if you have the memory for it (recommend 36GB). I run a I7-860 for my home server...and sure...I could get a better power usage setup, but the extra power is great for doing back ups and all the playing around I do...and I had it already. Infact I now have three of those CPUs in the house. I term it the best bang for the buck right now since people are selling used LGA1156 CPUs so cheap. Plus they are great for home servers since they have the VT-D option and the ability to overclock...which you can't get with any newer Intel CPU that I know of.

No problem, heh. I should have included the link. On his second link here :
http://www.extrahardware.com/clanky/intel-pentium-g2020-ivy-bridge-very-low-power-consumption/strana/0/1 theyre using a Gigabyte GeForce GTX 680 OC, 2 GB (GV-N680OC-2GD) which does power down significantly at idle.

Interestingly in that review, at idle the FX-6300 burns 1 watt LESS than the G2020.

Even an overclocked Thuban 1100T wouldn't pull those kinds of watts. If Semprons were that inefficient, AMD never would have sold a single one. That's overclocked 8350/9370/9590 territory.
