HI Friend,
The CPU Comparator provides an easier way to compare speed of your processor.

Thanks,

Even if two identical-looking processors both rolled out of the Pentium Intel factory, that doesn't necessarily mean they're going to be the same. Not every Intel processor has the same clock speed, which is the number of processes it can perform in a second. If you want to compare the speed of two or more Intel processors, you're going to have to keep three very specific things in mind.

Right now, what you want is the Core i3/i5/i7 series. Core 2 duo/quad models are outdated.

To compare the individual models, check the site that daisy listed.
