They are both based on same sandybridge architecture, i5-2415M has 3MB L2 versus celeron B840's 2MB. i5 also has 4 threads.

So Clock frequency IS the main differentiator here, 1.9Ghz vs 2.3-2.9Ghz (with turbo), which probably corresponds to 30% to 60% difference in general.

Specs of both processors:

Oh interesting. The desktop I was referring to has a 4 year old Celeron at 1.9Ghz, so possibly its older architecture makes it more different, but not sure.
