Check what scaling govenor is being used on the DietPi?
It has been set as interactive for a long time on the pine64 images... I think DietPi was a bit daft at one point and had it set at ondemand... maybe it still is? Also see what happens to your benchmark when you change it to performance.
Code:
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
