The WRX compared to the WRX STI is a rule of thumb of about a full second slower to 60. But the differences don't stop in just strait line speed. The STI is also significantly better on handling, braking, and top speed. The WRX is a mean machine, don't get me wrong, but the STI is a thoroughbred sports car.
