What is the difference in performance between CPU models?
Like with the new Core i3 4th gen models, Core i5 models and Core i7 models. How much of a difference is there really between the Core i3-4130 and the Core i3-4340 or the i5-4430 and the i5-4670.
quite a big gap going from the i3 to the i5 because you are going from dual core to quad (on desktop cpus, but some laptop i5/i7 are dual also), but not as much to the i7, as that is still quad (except the super high end socket 2011 cpus).
This can give you a rough idea of performance difference:
