Dear list readers,
sorry for bothering you.
I want to buy a new mainboard with the following features.
1. It has to be supported by coreboot. 2. I want to have a board with onboard graphics, since I do not play any games. I hope to save power this way. 3. Probably it should support a processor with at least 2 GHz. 4. Firewire would be nice.
(I want to maybe do some video editing once every three months.)
Of course I read [1]. It looks like I have to make a decision between onboard graphic and firewire – but 2. has higher priority (or is my assumption regarding power consumption wrong).
So this is my result.
- GIGABYTE_GA-2761GXDK [2] (the link in the wiki on the board [3] somehow leads to [4])
Unfortunately this board seems not to be available in Germany/Europe(?). Therefore I weakened requirement 1. a little bit to 1‘.
1‘. It has or will have coreboot support.
That is why I am planning to buy the ASUS M2V-MX SE [5] having read the announcement from Rudolf Marek [6].
Any thoughts/suggestions from you to my decision/requirements.
Thanks a lot for your time.
Paul

Buy a gigabyte M57SLI. It fits all these requirements.
The main downside is that it has soldered-on rom chip.

This board is not available anywhere, afaik.

Yeah, that's another option, and it has a socketed rom chip.
Thanks, Ward.
Dear Ward,
thank you for your answer.

According to [1] it does not fulfill 2., or do I miss something.

Ok.

That is unfortunate. For clarification: This board does not fulfill 4.

Ok. It looks like, I am going to order this next week.
Thanks,

Ah, you're right, I looked over that one requirement.

Great. I'm sure Rudolf will be glad if you can help test/port the board.
Thanks, Ward.

Please note there is no support yet, still WIP. And it will take some time.

Yes I know, take your time and thanks in advance to you and everybody to make this possible.
I ordered the board yesterday. Those who are interested can take a look at [1].
Later,

Depends a lot on which graphics card you want to use.
Here's a quick test I just did on my ASUS A8V-E Deluxe, with setting the CPU frequency scaling support in Linux to "powersave" and "performance" (all tests done with the proprietary BIOS):
No graphics card, performance: 61.6 W No graphics card, powersave: 55.2 W
Old PCI VGA graphics card, performance: 64.8 W Old PCI VGA graphics card, powersave: 58.6 W
Cheapo PCI-E graphics card, performance: 74.3 W Cheapo PCI-E graphics card, powersave: 67.8 W
Here's the lspci for the cards:
00:0c.0 VGA compatible controller: ATI Technologies Inc 3D Rage Pro 215GP (rev 5c)
02:00.0 VGA compatible controller: ATI Technologies Inc RV370 5B60 [Radeon X300 (PCIE)] 02:00.1 Display controller: ATI Technologies Inc RV370 [Radeon X300SE]
There are certainly a lot more power-consuming graphics adapters out there, this is the cheapest PCI-E one I could get (I couldn't care less about 3D performance).
HTH, Uwe.
Dear Uwe,
thank you for sharing your results.

Do you remember which kernel you used? And how did you measure the Watts?
No graphics card, performance: 61.6 W No graphics card, powersave: 55.2 W
Old PCI VGA graphics card, performance: 64.8 W
+ 3,2 W
Old PCI VGA graphics card, powersave: 58.6 W
+ 3,4 W
Cheapo PCI-E graphics card, performance: 74.3 W
+ 12,7 W
Cheapo PCI-E graphics card, powersave: 67.8 W
+ 12,6 W
I guess, one can say that the difference in the numbers with different governors are probably measurement errors.
Here's the lspci for the cards:
Thanks.

Now the interesting question is, how much more power a mainboard with onboard graphic is using compared to a board without.
HTH, Uwe.
Yes this helped. Thanks again.

They can be better, and worse, than when using discrete graphics. I am afraid software matters much more than graphics IP locality. :\
The only concrete increase in power consumption with discrete graphics would be the graphics RAM.
Of course GPU features matter more, and one reason for onboard GPU affinity is that those GPUs usually are less advanced than those on discrete cards - but surely a simple graphics card can still be found?
Anyway, I would argue that no PC-like system except possibly the XO laptop comes even close to power management worth mentioning.
