In order to get reliable benchmark results, you need proper cpufreq driver with cpufreq statistics reporting enabled (CPU_FREQ_STAT). The benchmark tool needs to set the cpufreq governor to "performance", take the snapshot of cpufreq stats and run the tests. After the benchmark has finished, check the cpufreq stats again. We expect that only the time spent on the maximum clock frequency should increase in the statistics. If you see any counter increases for the other frequencies, then there was thermal throttling kicking in during the benchmark and you know that your results are not trustworthy because the time and duration of throttling intervals is a bit less predictable.
