That's not the correct analogy, because the carpenter uses the screw driver as a tool, not as a platform. The screwdriver is analogous to code, not the CPU.
I would absolutely ask a carpenter how quickly he can complete a project, and I would hope he has a realistic first order approximation of how fast he can complete (process) screw driving tasks.
That said, I disagree with the question being discussed here, because I'd rather just ask him about his speed and performance; I wouldn't ask him how fast he can screw things in :) (that's a minute detail compared to the actual work).
