    Comparison of these processors should always take into account the turbo boost profile in addition to the clock speed and L3 cache.

    Turbo boost works by stepping up the clock in 133 MHz intervals up to a maximum value for a certain number of active cores; the "turbo profile" is the max turbo multiplier for 2 active cores / 1 active core.

    Core i5-520M
    L3 Cache: 3 MB
    Nominal clock: 2400 MHz
    Turbo profile: 2/4
    Max dual-core clock: 2667 MHz
    Max single-core clock: 2933 MHz

    Core i5-540M
    L3 Cache: 3 MB
    Nominal clock: 2533 MHz
    Turbo profile: 2/4
    Max dual-core clock: 2800 MHz
    Max single-core clock: 3066 MHz

    Core i7-620M
    L3 Cache: 4 MB
    Nominal clock: 2667 MHz
    Turbo profile: 3/5
    Max dual-core clock: 3066 MHz
    Max single-core clock: 3333 MHz

    Thanks, but that has been discussed in length in about 20 other topics as well :)
