Clock for clock the i3 will be a little faster, but not much. If you had a Core 2 Duo e7500 ... compared to the i5-530, they both have the same clockspeed, but the i3-530 has integrated graphics, more cache, and a different socket with native DDR3 memory controller built into the CPU.

Check the above link for a clock for clock benchmark and you will see the i3-530 is a little faster overall, but not a huge difference.
