In all other cases, your latency is bound by your frame time cap.

Say he caps framerate at 140fps, and the GPU ramps down the clock so it takes 7ms per frame to finish working on it, if the speed of the GPU is doubled and the GPU only takes 3.5ms to finish each frame, the 3.5ms in extra idle time would be a latency improvement. The only requirement is that the framerate cap be implemented earlier in the pipeline than the GPU starting work on a frame.
