The clock speed of ARM chips that have big.LITTLE cores is not very meaningful. The LITTLE cores can run at lower frequencies than the big cores. The Apple A series (and M series I will say with some confidence) support heterogeneous operation so both sets of cores can be active at once. The big cores can also be powered off if there's no high priority/power tasks. The cores and frequency can scale up and down quickly so there's not a meaningful clock speed measure. The best number you'll get is the maximum frequency and that's still not useful for comparing ARM chips to x86. Even Intel's chips don't have frequency measures that are all that useful. Some workloads support TurboBoost but only within a certain thermal envelope. Even the max conventional clock for a chip is variable depending on thermals. I don't think it's worthwhile faulting Apple for not harping on the M series clock speeds since they're a vector instead of a scalar value.
