Uhhh, no. Not at all.
E9X M3 power curve - nearly perfectly linear
F10 M5 power curve - a big hockey stick (totally flat in power for the entire top 1500 rpm)
Do I really need to paste in images of these stark differences for you to see them?
Now that being said, up to about 5700 rpm the torque and power curves are very similar and will feel so.
