Re: [dwm] Low Power Fanless Computer

2009-04-26 Thread Kai Großjohann
I suggest to buy some sort of laptop or netbook and ignore the internal 
keyboard/display.


Perhaps the Dell Mini 12 is good (since fanless) but I don't know how it 
fits into the other requirements.

Hi,
after a few months of latop-only computing (my good old P4 1.8Ghz is now -
after 7 years - a Windows machine in our household), I plan to switch to a
normal computer again.

My requirements are the following:

   o Low power consumption (<  10W; 25W upper limit)
   o Support for major Free Software operating systems (no strange, custom
 GNU/Linux distributions), especially GNU/Linux or NetBSD
   o Fanless and no moving parts
   o No proprietary drivers, etc. (BIOS and bootloader acceptable)
   o Standard form-factor or custom case/enclosure (if so, hole for rp-sma
 connector)
   o Smallest form-factor that is possible (I don't understand why computers
 are still the size of a bottle crate)
   o Standard connectors (USB, VGA/DVI, Ethernet)
   o VESA mount (if possible)
   o low budget (<  500€)

After I found no RISC processors or SOCs, I looked at x86 CPUs. There three
low power architectures: VIA C7 and Nano, AMD Geode and Intel Atom.

VIA's technology (especially the C7) seems to be out-dated. VIA offers a
mini-itx board with its Nano CPU (VIA VB8001), but it has small fan and its
power consumption is slightly above the limit.

AMD's Geode is obsolete as well. The Geode LX family has the advantage of
low power consumption and small form factor. However, the performance per
watt ration is low.

Intel's Atom processors are modern and have probably the highest performance
per watt ration. However, the smallest affordable form-factor is mini-itx
(I talked to several companies that manufacture smaller industrial boards,
but the price performance ratio was terrible and buying one of those would
be my last option). Similar to the Nano most of the Atom Boards have a power
consumption that's a bit above 25W (there are the Z510 and Z530 embedded
Atom CPUs, but the come with the GMA 500 graphics chip which has no free
drivers). Nvidia's Ion, especially the Acer AspireRevo, seems to be quite
promising, but has proprietary drivers.

I wanted to ask you (because you very likely use your computers the same way
I do) whether you think the Geode is sufficient for the next three years or
so, otherwise would buy a cheap Atom mini-itx computer.

Usually I use my computer just for programming, typesetting (mainly
with groff and heirloom-doctools, but also occasionally with LaTeX),
reading and research. I don't need any computing power for simulations,
calculations, etc.; I can get access to bigger machines if I really have
such special tasks.

What bothers me a bit are these multimedia applications (video codecs,
etc.) and particularly web applications. I'm really not sure if the
Geode would be able to render on of these new JavaScript + HTML =
graphics-and-user-interface-API web apps in one and a half years or
so. Moreover, I can't imagine the CPU to decode a medium-sized h.264 videos
which seem to have become today's quasi-standard.

Maybe you know a better alternative.

Matthias-Christian

Proprietary drivers are not acceptable for. I ported the Nvidia drivers to
the latest -mm tree for a while and that was no fun. X.org updates broke
them entirely and you had to wait a week or so to use 3d acceleration again.

The BeagleBoard looked also quite promising, but has no Free Software graphics
drivers and no mainstream distribution support (like most of the exotic ARM
SOCs and boards). The Loongson could be an option too, but it requires as
much power as an Intel Atom. It's a pity that Intel dominates the CPU market
(especially on Desktops).

Moreover, the dev kits and evaluation boards for ARM and MIPS are quite
expensive, most CPUs are very slow and they don't provide a decent case for
their boards. But I would be really happy if someone could recommend a nice
non-x86 system to me.

However, modern the R in modern RISC processors isn't appropriate anymore
since their instruction sets aren't reduced anymore. This is particularly
true for ARM. I would really like to see the first mainstream, low power
asynchronous CPU.

I don't know, my Radeon card in my laptop works pretty bad (especially on

I have been looking into this kind of thing myself. What I found is
that getting an Atom nettop computer would be a significant downgrade
in performance (from my Pentium M). Both in performance and
power/Watt. Also, GMA900 on the EEEs is slow enough that rendering
webpages is not very smooth. Imagine what that would be like in 3
years.

I looked at two things. First is the Neuros Link, which has a low
power Athlon LE-1660. The form factor is not that small, and it does
have a fan (supposedly quiet), but it does accommodate a full hard
drive, has eSATA, DVI and HDMI. The problem with it is the ATI
graphics chip... Linux support for these is still terrible, despite
the recent releases of documentation. The open source driver is moving
very slowly for the AMD/ATI hardware.

Though, Neuros Link is very cheap ($250):
http://www.neurostechnology.com/neuros-link

Another item is the Dell Studio Hybrid. That thing gets good reviews.
It is a real computer, unlike the Atom stuff. There is a Core 2 Duo
laptop processor in there, which is the best performance/Watt you can
get. Apparently it is very quiet (does have a fan), draws 25W at idle,
and 40W max, and has a GMA X3100 graphics chip. DVI and HDMI (though
only one can be active at a time, so no dual screen). It can be had
for $500. Sadly, it is not small enough to be VESA mountable. Also, no
eSATA, so you are stuck with a single internal drive.

Anyway, I think both of these options are imperfect, but maybe someone
will find them useful. I am waiting for the NVIDIA Ion stuff to come

After my router (which has a Geode LX 800) had a 1/10 of the Whetstone score

While I really like Asus products (I'm very happy with my eee), maybe

If you want to have your own server the idea of accompanying one of
