The Super Fast Computer Chip - Solution

The distance a signal can travel in a single clock cycle of the proposed chip is only

(3 × 108m/sec) / (3 × 1014/sec) = 10-6 m.

So signals cannot travel from one end of the chip to the other during each clock cycle. It is highly unlikely that such a computer chip can function properly so most probably the person is trying to con you.
Don't give him/her your money!
