ITX Motherboard, Continued
Unlike the Atom Notebook solution, the 945 desktop chip set is fitted with a dual channel memory interface. Not every manufacturer of Atom boards implements both slots, though. The DDR2 memory speed is limited to DDR2-400 and DDR2-533, but technically the 945GC chip set is capable of DDR2-667. In our tests we selected timings of CL 3.0-3-3-8 due to the lower clock speed.
The dual interface has a measurable speed advantage, but not one large enough that the user is likely to notice in actual use.
The dual interface’s other benefit is that two memory modules can be used, which can save you some money, since for a given memory size, two modules are cheaper than one. According to the Intel specification, the 945GC chip set is only capable of handling a maximum of 2 GB main memory, but we had no trouble starting the board with 3 GB.
The VIA sound chip supports 5.1 audio. The board has no digital output at the I/O plate, which means that a separate adapter must be purchased.
The inclusion of a PCI Express port means that the board layout is about 1” (3 cm) longer.
SATA 3 Gb/s and IDE

Where's Linux tests?.Reply
This saved me time researching for an assignment :)Reply
Shouldn't it be on 9 - cooling and temperatures,be idle and load,instead of idle and idle? >.Reply
When you look at the power consumption on load and compare it to the slowness of the chip while performing on load, it becomes clear why it only uses 4 watts more...Reply
A CPU without a platform is useless.Reply
Analyzing the Atom platform quickly from the power/performance perspective.
CPU name / idle W / load W/ Lame (seconds) / total Lame W used
Atom 230 / 40.5 W / 44.2 W / 773 s / 9.49 W
Celeron 220 / 44.9 W / 55.4 W / 375 s / 5.77 W
E2140 / 58.5 W / 69.5 W / 271 s / 5.23 W
Clearly the Atom platform is the most inefficient power/performance wise.
At idle you might win some W, but as soon as you try to do something you spend more power and waste more time.
There are other things you should consider, the frustration of having to wait for things that now we are used to do near instant and the inability to play HD video or use any significant graphics.
The only thing positive for atom is it's price. It's cheap. And maybe with a new chipset it might even be power efficient. But for now it's just cheap.
I wonder if it'd be able to play games if one were to equip it with a pci based 2400pro & 4gb of memory?Reply
Also, I wouldn't be surprised if someone invents a voltmod for those boards, so they can increase voltage for cpu, mch & ich enabling 2ghz+ speeds
so in other words atom is pretty much a failure unless it's pumped into a tablet or umpc? and even then apparently isn't cost effective or readily available, nice...sounds like a great product launch.Reply
I ran a google search for ECS 945GCT-D mainboard, and could not find it.Reply
I don't get it, why do you publish tests with products that don't even exist on the vendor web site?
Thank you, anyway
Raiden, while your numbers are true, I think a fairer comparison would be to use 773s for all processors (meaning the rest go to idle alot quicker). I suppose you can power your computer down afterwards or start up a web browser etc.Reply
Atom 230 (773s load / 0s idle) : 9.5W
Celeron 220 (375s load / 398s idle): 10.7W
E2140 (271s load / 502s idle): 13.4W
Sempron LE-1100 (43.9W idle, 70.4W load, 301s load / 472s idle): 11.6W
Sure this is biased against the Atom (not going idle at all) but with 4W delta between load and idle, I am too lazy to change the numbers already used.
I find it comparing the Atom to a Sempron LE-1100 more and Celeron 220 interesting:
"A Celeron at 1.20 GHz is 35% faster than an Atom at 1.60 GHz, but the Atom only consumes a fraction of the energy used by the Celeron. The AMD Sempron system, which uses almost the same energy in idle mode as the Atom system, is 43% faster."
in anyway, despite of the low power and low performance, i still think it'll also be good as simple file server or home server besides as umpc. for experts, it'll be enough for some robotics and control application. just like the one used for Aiko in http://www.projectaiko.comReply
