Both Laptops are HP Pavillions? I had to search specs to see what clock speed the processors use in the machines.
OK, the one pavilion running the core i3 is a 2.2GHz processor, and the core i5 is a 2.4GHz processor (unless I have the wrong HP brands).
I took these two processors, and did a comparison over at intel, and here are the results

They are almost the same, its just that from the comparison, the core i5 is better slightly, as it has more features, like the turbo frequency it runs with. Have a look and see which would be better for you
