The “Turbo” button on a 486 PC was actually a CPU clock speed limiter. It was necessary to play older games who had a hardcoded framerate that depended on clock cycles, because they would otherwise run too fast.
But for marketing reasons, IBM labelled the toggle as “turbo” instead of a speed limiter.

well, actually…It usually changed the clock speed on 286 PCs, but on 486s it often disabled the L1 cache or introduced additional waitstates instead
