How much faster in percentage is 1 Hz from a Core i5 CPU compared to a Core 2 Duo CPU?

If someone could show me their sources and/or calculations, that would make the answer even better.

Any input would be greatly appreciated! 🙂

Update:

I’m asking to compare the clock speeds of the i5 architecture with the core 2 duo architecture assuming everything like cache memory and core count is fixed to the same amount.

Is it accurate to say that core i5 2.6 GHz ~= 4.33 Core 2 Duo GHz?

  • Your question makes no sense whatsoever…

    Core i5 would be much faster and better than Core 2 Duo, since it has newer technology. Forget about the GHz clock speed, that does not matter.

    First of all, an i5 is a quad core processor (desktop models are, not laptop ones), while Core 2 Duo is a dual core….

  • You mean how much better performance do you get per clock?

    Depends, but from the Core 2 Duo to the Ivy Bridge, you will get anywhere between 15 and 40% better performance per clock (according to intel)

  • Intel core i5 way newer which means usually means faster
