ION overkill for CarPC?

**upspace** · 09-15-2009, 03:47 AM

those new ion combos sound very promising (i.e. ASROCK ION 330) but let's face it. isnt an full hd capable onboard chip (nvidia9500) an overkill for a Car PC attached to a (low) quality 7-8 inch LCD panel?

the price is higher energy consumption (around 31 watts idle to 40 watts) compared to the onboard intel 950 solution (12 to 20 watt) which is more than enough for video replaying and even the most sophisticated gps 3d rendering in future.

And energy consumption is critical in car environment.

Energy consumption is not as critical a factor as it was a few years ago.

A few years ago, there were only a couple or DC-DC PSU's available and the beefiest was capable of only 150w output. Now there are DC-DC PSUs that are capable of more than double that output.
While the DC-DC PSU product selection may not have a PSU capable of powering a high-end gaming rig or dual-processor CAD workstation, there are enough models available to power any reasonable setup in the car.

And I wouldn't use an Intel Atom processor to do 3D rendering, especially with the Intel 950 chipset.
Capable? Perhaps.
Practical? Not at all.

yeah but i am scared about having 10-20 watts in idle to full load compared to 30-40 watts on a car battery when engine is not on.

so you recommend the asrock ion nettop then? i also prefer this one because integrated cd-rom, 320 gb and quick boot.

Had the ION's been available when I built my carpc, that definitely would have been my choice. The power difference you are talking about isn't really that much, but the performance potential is.

Here's my opinion. Unless you have 3 kids traveling with you all the time, you probably won't be watching any movies in the car. I know because I don't either. I mean who'd watch it in the car with a crappy 7"er instead of watching it at home on a big screen. Not to mention watching 1080p on a 7" which most screen don't even have the resolution support.

I had a dedicated GPU in my car for about a year, then i realized that its never even used, which i consequently decide to remove it. My new carputer I've also decide to get an atom board without ion, to save cost, and unnecessary heat.

The only reason why I'd get an ION is for the option of multiple video outs. The intel 950 chipset will not support using the onboard AND PCI video. Meaning, you have to use one or the other, not both. This is extremely limiting IMHO. The nvidia ION board will probably support dual video out onboard and you can add 2-4 more via the external PCI-E. That's a potential screen for everyone in the car!

overkill is very relative-- as was pointed out to me before(the member name escapes me), some members prefer to play blueray in their car, so they don't have to buy 2 different discs of every movie-- one for the car, and one for home.

also, with audio processing, a atom can, and does work, but i would never have a problem upgrading to a faster processor for faster/better/more processing.

and the cruel reality is that the newer windows os's are starting to become heavily reliant on better systems than what they used to (we know kev000...)

, so a better system is starting to become a requirement.

I dont know what mainboard you are using but everyone with a PCI slot is able to do dual view.
As long as you use a PCI VGA card.

In my car I use the D945GCLF2 (intel 950 chipset) with a ATI 7000 Radeon PCI VGA card.
This card as a VGA and a TV-out.
Touchscreen is attached to the VGA and both rear headrest screens are attached to the TV-out. (I disabled the onbard VGA)

Now the kids (3 in total

) can watch a movie while I navigate on my touchscreen.
Use the have AVI's in the car but I notice that when using Sygic Drive the movies started to slow down.
CPU didn't (Atom 330) like it mutch.
thats why I converted them all to MPEG. Good enough for the 7"screen I have.

Correct. You can use a PCI video card that has dual outputs. What I meant was you can't use the PCI video AND the onboard at the same time. The bios disables the onboard if you use the PCI card. It probably has something to do with only 1 PCI lane for video... idk for sure. All I know is I'm told by intel that there is not intel chipset with onboard video that will allow you to use both the onboard and any external video at the same time.
