It is possible that you are right and this is a cause for the relatively low scores that I have seen for Zen CPUs vs. Apple CPUs in several Anandtech reviews, i.e. if they had used mediocre coolers for the Zen CPUs, resulting in high CPU temperatures.



While for Intel the turbo clock frequency varies with the CPU temperature only on a few SKUs, those with "Thermal Velocity Boost", on all the Zen CPUs that I have used the turbo clock frequency appears to be temperature dependent.

Therefore, I have seen noticeable benchmark result differences between hot Zen CPUs and less warm Zen CPUs.


I use only high-quality coolers, which maintain a low CPU temperature even under full load.

For any single-thread benchmark, the maximum turbo-clock frequency is maintained indefinitely, no matter how long the benchmark is, as the power used by a single core is no more than 20 to 30 W.

For a multi-threaded benchmark, the CPU would work at its power limit and the clock frequency during a long benchmark depends slightly on the quality of the cooler, i.e. on the temperature corresponding to the power limit.
