Nah, chips are manufactured in best version and then damaged/fused/lock to downgrade them to create cheaper version (in the same series)

Its cheaper to have a single production line and then lock off features.

As crazy as i sounds it actually cost a little bit more to produce inferior version sold at cheaper prices.

The overclocking was a 'premium' feature due to possibility of melting the chip. But nowadays the temp sensors cut power to prevent catastrophic failure.

Also worth mention the downside to upclocking voltage is increased physical degradation of cores, ie lower lifespawn of cpu.
