There is more to it than the throughput of the processor. On the robot there will be less memory (and paged memory may be disabled), less cache and less non-volatile storage though I reckon one could attach a USB drive. I think the core of the i7 is roughly 25X faster (it is hard to make a apples-to-apples comparison) but the effective throughput of the i7 is much higher.
