I want to have a dedicated machine for downloads that I can leave on 24/7. I've got two old P3 866MHz machines (with Asus CUSL2 motherboards) that I built back in 1999. One is set up as a file server and runs Windows XP without problems. I only turn on this PC when I need to access the files. The other one does nothing. Both have 256MB or more RAM.
According to the Wikipedia
CPU power dissipation page, the P3 866 draws about 30W whereas the Atom 330 draws only 8W.
My question is should I just use the file server, use the spare, or should I get an Atom 330?
Heya,
No. The ATOM is a good CPU for low wattage 24/7 machines. But the problem right now is the motherboards that they're stuck to right now. Intel hasn't gotten on board with understanding that offering a super low wattage CPU is pointless if the mainboard and components bring the total usage up into the 40+watt range.
The reason I bring this up is because a 780 series AMD chipset with an Sempron 2.7Ghz 45watt CPU with quiet and cool enabled is way more powerful than an ATOM, cheaper, and sits around 37~50 watts between idle and loads.
So you then wonder... what's the point of an ATOM build if the total wattage ends up in the 30's and 40's? Then you look at a higher wattage CPU like the Sempron and wonder why it ends up being comparable to the ATOM machine's total wattage usage. You then realize you should just save the money, build a Sempron system, and wait for Intel to figure out why their ATOM systems are not good enough yet.
Alternatively, if you look into a netbook chipset as a mainboard, you can then couple an ATOM with it for very low wattage. I measured my netbook's wattage draw from the wall at around 27watts running XP and some applications.
Here's what I would use as a download box:
$95 - Sempron 2.7Ghz 45W & Asus M4A785-M mATX.
That setup can be configured to draw around 40watts with the components (drive, etc) for a 24/7 download server. I'd recommend it over an ATOM build since it's more powerful, cheaper, and has way more expandability (this puppy can instantly be a HTPC too, complete with HDMI output and a good GPU for decoding).
Drop in some cheap ram, a low wattage PSU, an an HDD and you're done. You can build it into a very small micro case. You can run Linux or Windows to your whim. And it won't crawl using flash/java the way an ATOM does (it's pathetic how bad it performs with flash).
Very best,
🙂
