Try it - you will see it does. But the basic cpuburn-a53 code is flawed as it assumes 2, 4, 8 processors and so only runs 4 threads on the RK3399 hexa core. Linux big.LITTLE schedulling is smart enough to ensure 2 go on the A72s, but even so only heats my system to 65 degrees after 10 minutes.

Better is arguably cpuminer benchmarks which use neon instructions. Seem to remember a thread somewhere of folks measuring actual power usage to substantiate the "better" part of this. But is e.g. part of sbc-bench which also has some neat background monitoring (if you are not already running a monitor). And it is easy to modify the script to avoid the other benchmark bits and run cpuminer for 10 minutes if you wish (which gets my setup to 72 degrees).

Code:
...
        CheckRelease
#        CheckLoad
        BasicSetup >/dev/null 2>&1
        InstallPrerequisits
        InitialMonitoring
        CheckClockspeeds
        CheckTimeInState before
#        RunTinyMemBench
#        RunOpenSSLBenchmark
#        Run7ZipBenchmark
        if [ "${TestNEON}" = "yes" -a -x "${InstallLocation}"/cpuminer-multi/cpuminer ]; then
            RunCpuminerBenchmark
        fi
        CheckTimeInState after
        CheckClockspeeds # again after heating the SoC to the max
#        DisplayResults
    fi
} # Main
...
    "${InstallLocation}"/cpuminer-multi/cpuminer --benchmark --cpu-priority=2 >${TempLog} &
    MinerPID=$!
    sleep 600
