No, they do not produce the same speed, it might be in the same ballpark though.
For example we use CI 10 on our 737s and CI 7 on our A320 family. Even on the airbus fleet it doesn't produce the same speed though, depending on FMCG manufacturer it will give a 250kts or 270 kts descent speed for example, while CI 10 on the boeing will produce a 250kts descent. Climb and cruise speeds are a completely different problem altogether.
I would suggest checking out
Boeings and
Airbus information on the subject.
