Is there anywhere that I might be able to find a CPU comparison; I'm tring to understand VIAs CPU line on the ITX line of Motherboards, as how they relate to Intel and AMD Processors.

ie
C7 is most like a XXX Intel or XX AMD chip, or something similar....


I dug around here and google, and I see a lot of 1.5 GHz this and 2.6GHz that, but lets face it, a 2.6GHz Intel Chip is not the same as a 2.6GHz AMD...So I'm having a hard time relating how fast a C3 or C7, also I am assuming that the terms Eden and NanoBGA are chip types (like Pentium or athlon)

A 1Ghz C3 is equivalent to a 700-800Mhz Pentium III

Via based their architecture on Intel, not AMD.

micro-atx and c2d ftw, ydig..

best of luck getting it figured out!

Thanks for your opinion, but this does nothing to answer the OP's question.

Micro-ATX is just a formfactor. The only bearing it has on a vehicle installation is space requirements.

huh?

I'm assuming "c2d" means Core 2 Duo, but that's as far as I got...


he's going to need a lot of luck figuring out what you wrote there... I sure as hell couldn't fugure it out.

I thought this was a forum, not a text message with your buddy. I guess I was wrong

A c2d is a good choice for a CarPC if you have a) money and b) the need for that power. For instance being in university for 2 engineering majors, I need to use many very high end and powerful applications on the go whether it be rendering something on my drive up the interstate, or run a transient simulation on one of my circuits. So I need to power.

If you are just doing a music/nav/video then something like a via 1Ghz - 2Ghz is plenty and energy efficient.

and we gatz 2 save da bandwith yo!!!1one!!

Ok so I get that the VIA c3 1.0 GHz Processor relates to an Intel P3 about 700 too 800 MHz,
how about a C7 1.2GHz, or a C7 2.0GHz.

I ask, as I have been using a Laptop as my CarPC, I am very familiur with Intel, and AMD Processors, and how they relate to each other, and how to determine speed/power, but I'm not sure what the VIA is compairable directly to, is the C7 2.0 GHz equivalent to a P4 2.0 GHz, or more like a 1.6.

I've been thinking about moving to a Mini ITX board, but if it can't handle all the applications which could include some moderate Video rendering, I was thinking about 2 PicoITX boards!!

Why 2 PicoITX boards? How would this give you any more processing power for any given application. It's still 2 separate PC's. Not really any way to combine the power. I'm confused...

I would split, the applications between each Pico... I already have 2 screens, One in the dash where my head unit would be, the other would be a flip down where my rear view is -removing the rear view.

Why not just upgrade your existing computer to something more beefy and just run all the displays from that computer? That's kind of what my friend did... he had dual monitors, on rearview, one at the headunit.

Well, I'm having a hard time finding a GOOD laptop to replace the one I am using, that supports dual monitors...but lets not focus on why or what I'm doing with my install, really I just want to see what the difference is in CPUs!
The laptop I was using was a p3 1.0 GHz, it could barely handly the load I was putting on it, if I upgrade to a new Laptop, I will need to spend atleast $1200, I can build a decent MicroITX for 300 - 600, or 2 Picos for about the same...depending on how a C7 1.0 GHz Actually runs I may get better performance with 2 boards...seeing as how I'm not sharing the bus, memory, video amungst all the apps...

Mini-itx and nano-itx are just formfactors. You can get a C3 on a uATX board, and a core 2 duo on an itx board.

If you want video rendering, then the via boards are out because of the Apollo chipset they use which is useless for rendering. For mpeg decoding and such, it is fine. But for encoding, it just dies. It is not even fully DX compatible.

If my post was not clear...

Core 2 Duo and micro-ATX formfactor for the win, can you dig it...

EQNish

I understood perfectly, however I didn't ask about Core 2 Duo, or Micro ATX


basicly My situation is, I dont really ahve the space for anything biggin then an Micro ITX, I might be able to Stack 2 on top of each other, but not likely. so the smallest MoBo available is the Pico ITX, but I have yet to find any one that can give me an idea of the speed these little things put out. No one seems to understand that I am looking to see how the C7 CPU chips fall in line with Intel or AMD chips, ie some one said the C3 1.0 GHz is about the same as an Intel PIII 600, thats perfect I now know that a C3 is slow as crap and wont handle my application.

while I would love to put in a c2d 2.6 on a nice banging MoBo, there is No room even 5 CM more then the 17cm, will be Pushing my space constraints.

so again I ask How do the C7 CPUs on the VIA mother boards compair?

Is the C7 1 GHz, like a P4 1GHz? More, less? the same goes with the C7 1.2, or the C7 1.5, how about the C7 2.GHz, is it anything close to an AMD athlon 3200+, or maybe (if I was lucky) a AMD AM2.

I know they don't run as hot as the one listed above, and they dont ahve the power consumption, but right know neither of those factors mater as I don't really ahve the space for anything other then Micro ITX, Nano ITX, or Pico ITX....


Now I know some one is reading this and thinking what a whinny little B...H, but I ahve looked everywhere for this compairisons, I have yet to find anything I asked here, well becuase this forum is prettymuch dedicated to Embed systems, which is what this CPUs, and form factors are ment for. I would have asked at Mini-itx.com, but I can't find there forums!

In general you can think of the C7 as about 20% slower than a Celeron Mobile of the same clock speed.
