Well, P4's clock was achieved with 31-stage pipeline, which was a bad idea. If you compare with what came after P4, there was more than slight increase in clock

- zokier 13y agoWillamette and Northwood (ie the original P4s) cores had 20 stage pipeline, compared to Nehalem with 24 stages and Sandy, Ivy and Haswell having 19 stages. And those Northwood cores reached 3.4GHz, compared to 3.8GHz of the infamous Prescott with it's 31 stages. That is fairly meager clockspeed increase, and based on that I'd argue that the extreme pipeline depth was not the major contributing factor in pushing the clockspeed of P4 higher.
