What is the difference between a pentium i3 processor and a intel core duo

Hello, I am not a computer wizard obviously, so I was wondering if you might be able to help me out with this. We are purchasing our 16 yr old son a laptop for Christmas and I needed to know the difference between a pentium i3 processor and a intel core duo P7575 and which is preferred and why. Thnx!

  1. The difference is well, a different processor. Need more info to see which laptop is the overall better laptop.

    Or how about filling out this guide so that we can help you select a laptop?

  2. this is the broad comparison chart and probably won't tell you anything :(

    Well the basic difference is that i3 are the newer models, all of them are dual core.
    the Core 2 duo are older like 2-3 years depends which you choose.

    i3 have 2 versions last years that are marked with 3xxM and this years 2xxxM(most often 2310M)
    A new i3(2xxxM) is better than any i3 from last year and much better than core 2 duo

    Here is a rule of thumb:
    i3-2xxxM @ 2.100 Mhz is more than i3-3xxM @ 2.400Mhz is more than Core 2 duo @ 2.800 Mhz.

    Also give the entire chart with considered models and why you need it. Because computers are more than just processor.

    Depends on the budget and the scarce data i give you this recomendation:
    Get i3/i5 2xxxM
    6-8GB Ram
    500 HDD(or more)
    GPU*ATI 6470(or higher, 6570 is better,5650 is better,4870 is better) or NVIDIA 525M(or 540M/555M)*
    Screen 15.6" Led
    This is approximatelly 600USD laptop (may differ but will stay in the +-100)


    *If you dont want him to play games on the pc dont get any of theese instead go for HD3000* But be warned he may a bit upset if you do that.
  4. The Core Duo predates the Core 2 Duo. It is slightly older in design. The Core i3 (Sandy Bridge) is basically two generations newer than the Core Duo CPU. Performance wise the Core i3 probably provides around 30% more performance if you were to it to a Core Duo with the same clock speed.

  6. Thank you so much Braincruser for replying! The information you gave was extremely helpful. Looks like I need to to a little more shopping and comparing. ;-) Thank you again and have a great one!
