My understanding is that in almost all cases that comes down to one of three things, silicon lottery, margin of error for tests conducted, and thermal management on the laptop side. The first two are self-explanatory. For the last point, the higher boost comes with higher power draw, making the i7-1185g7 more susceptible to thermal throttling. Marginal, but enough that some laptops might suffer for putting the more powerful chip in there. Overall I’d hedge my bets that the primary source of slower tests would be the limitations of testing methods used.
