    Which processor should I get?

    I've got a Motherboard that will take several types of CPUs. The three grades of Processor I'm looking at are Intel Celeron, Intel, dual core, and Intel Core 2 duo. Obviously the core 2 duo is the best cpu but is it the best for a carputer? Here is my thinking so far and you guys can chime in and correct me or add your ideas. Both the dual core and the core 2 duo are 65W cpu's while the celeron is only 35W. From what I have searched and read, less power consumption is usually better (less heat, less expensive power supply, etc.). The celeron processors are also cheaper (brand new ~$50 compared to ~$100+ for the other two). Are dual core or core 2 duo processors going to gain me alot in a car pc setting? Is it worth the price? Or would the Celeron be plenty of processing power? Oh, I forgot to mention all three are 1.8 Ghz. Thanks for the help.

    Dual core and Core 2 Duo are the same thing, only referenced differently.
    As far as the celeron vs C2D question, it's really up to how much performance you want. The Celeron will offer less performance than a C2D processor. Personally, I think that a Celeron will offer more than adequate performance for a vehicle installation, as well as provide the benefits of lower power consumption and less heat output.
    Have you looked in the FAQ yet?
    How about the Wiki?

    I would be more concerned with what kind of video you plan to run, I would ask yourself if you plan to run onboard video or separate video card.

    If onboard I would look at amd 780G they seem to be the best, I am personally stay away from all nvidia stuff until they get there bump and underfill issues solved with there chips, nothing like having your north/south chipset die on you and your whole mobo is dead.

    If you go with amd sadly you only have choice of amd CPU’s but I would go with a black edition and underclock and undervolt it as well and get mobile power consumption

    When your looking at mini itx make sure you get the manual and do some research on the internal sound and video, as well as the bios options, not all the motherboards and bios’s are created equal

    Im getting the J&W MINIX 780G-SP128MB it has everything that I need so far
    and getting 4gb of sodim ddr2 800
    paired up with amd x2 5400 black edition (65w)

    ill underclock and undervolt this 2.8ghz to something of 35w probably or less, and at the price of 66 bucks its a really nice cpu, people o/c this thing to 3ghz-3.5ghz, some even run sock undervolted meaning its going to be less then 65w, but i would like to go as low as possible and maybe scale the chip too with software in windows, so i can idle at lowest possible and when i need power have it scale up to whatever ghz i wish

    The performance (IGP) is far better then geforce 8200 and intel IGP’s you cant compare amd’s chips to intel ones that’s for sure but you can compare them price wise, you can also use a phenom 3 core for exceptional video combo, but this is more for HTPC’s then carPC’s unless you plan to play blue ray in your car

    Power consumption is also good with amd chipsets

    Do you mean "Celeron", "Core Duo", and "Core 2 Duo"? The Core 2 Duo is better than the Core Duo mobile wise. And of course it is faster/newer too. Celerons are plenty for the CarPC.

    You should look on ebay though. You can get working laptop pulls for under $20 for a Core Duo and about $40-$60 for some of the T7xxx line of Core2Duos. They work just fine. You will change motherboards before the used processor takes a dump, and even if it does, you saved enough to buy another used one!

    As to which to use, for the price, the power, and the wattage consumed, the C2D is the choice for me.

    But be careful with Socket M and Socket P. They do not work together and many chips with the same name use multiple bases when they sell. So you could buy a T5500 Socket M and T5500 Socket P. So be careful there.

    Thanks for all the input. I've been looking on ebay at used processors and I think that is the way I'm going to go. I'll just see what the best deal is that pops up. I still think I'm leaning toward just a celeron CPU because it is plenty of power for a carputer (like some of you have said). but if I find a good deal on a core 2 duo then I'll see if I can snag that. I'll be sticking with the onboard video on the mobo. It's really good so no need to upgrade to an external video card.

    I probably should have included this in my original post but here is a list of the CPUs that are compatible with my mobo:

    Any more advice or comments are appreciated. I've heard of underclocking (and overclocking) the cpu before but never heard of undervolt before. That might be an option to keep power consumption down but still get the better cpu. Are there any adverse affects of doing that? Can all CPUs be undervolted?

    Thanks for all the input. I think I'll keep looking on ebay for a good deal on the core 2 duo. I didn't know you could undervolt a processor. I've always heard of under clocking (or over clocking). How much can you safely bring the voltage down?

    I should have included this in my first post but the processors I was referring to are intel chips E4300, E2140, E1200, or 420. I think the 420 chip (the celeron) should be plenty fast and I can get it new for $40. However if I can find a deal on ebay for an E4300 (or similar) I might try that.

    undervolting and underclocking is the same as o/c just backwards you want to achieve lowest voltage, thus lowest power consumption, but at a reasonable mhz... so you work with the voltages and you can go as low as your mobo will be stable at, and you will keep the mhz at which that voltage works, you use benchmarks just the same to test stability.

    you can use software to create p states or whatever they call them, its when the processors step down the voltage and mhz auto when your cpu is idling etc...

    its very popular in notebook/laptops but for us in carPC's it should be just the same less heat is a good thing and less power

    that is why i was stating to use a black edition if your going amd, and get a decent clocked cpu then you can undervolt and step down the mhz, if you buy a cheaper cpu and not that high mhz then your not going to get a whole lot of power saving as its already pretty low and you will not have that much horsepower either, as the cpu would be a low end and not have the mhz or whatever to work adequately at underclocked speeds

    I would always stay with 2 cores, no less and you really don’t need any more, single core can be ok but I would not recommend it, 2 cores does wonders for multi tasking and threading, every application can utilize 2 cores at least, it gives also plenty of power for the OS and other peripherals to run in the background
