Probably still a "It Depends" answer? What do you want that CPU to do? Curiosity and Perseverance could last a long time and would a faster CPU enable significantly better science instruments? A rover might be able to travel farther autonomously, which is cool but it's a science mission, not a race course.

Why is this one lasting so long? Presumably we know the radiation conditions on the surface so testing more units in a lab is a better guide than one plucky helicopter.
