plz help me frndzzz

More about difference core
  1. i3 i5 i7, next gen intel chips, core 2 duo = old. i also dont understand what u want :/ in terms of performance, all i chips beat teh core 2 duo, i series is also measured in performance in terms of numbers as in 7 being highest and 3 being lowest, prices can vary tho.
  2. Generally speaking the current generation of Core i3/i5/i7 have about 20% more processing power than their Core 2 Duo counterparts.

    Core i3:
    -Dual Core CPU
    -Hyper Threading

    Core i5:
    -Dual Core CPU
    -Slightly higher clock speeds than core i3
    -Hyper Threading
    -Turbo Boost (it's like an automatic overclock if the CPU is not too hot)

    Core i7:
    -Dual Core CPU (models ending with M)
    -Quad Core CPU (models ending with QM)
    -Higher clockspeed than the Core i5
    -Hyper Threading
    -Turbo Boost
    -Virtualization (you can run multiple operating systems at the same time)
    -Has circuitry that allows for easier and more secure remote access for corporate IT departments to trouble issues in a business environment.
    -AE5 New Instruction set (No idea what this is)
  3. www.intel.com, they have details specs on all the CPUs there.

    I think i5/i7 have just a bit more raw processing power over any C2D chip LOL
  5. Check out this article. They locked different chips at 1 core and at the same speed. To try to get an apples to apples comparison. This is a really neat experiment because although it has no real world value it shows how much faster and more efficient the new CPUs are.

    Once you factor in the multi cores and the turbo the newer chips have the difference between a core 2 and i3-i5-i7 is huge.
