Benchmark of ODROID-XU4 with Active Cooler and Passive Cooler (XU4Q)

This wiki page shows benchmark test results to analysis and compare their system performance
with ODROID-XU4 and ODROID-XU4Q that equips with a passive cooler.

[ Benchmark (1) - Thermal and Frequency Performance Comparison ]

Environment and Instructions

  • sysbench 100,000 iterations
# sysbench --test=cpu --cpu-max-prime=100000 --num-threads=8 run
  • setting the max cpu frequency of CPU4-7
# echo 1800000 > /sys/devices/system/cpu/cpu4/cpufreq/scaling_max_freq 
# cat /sys/devices/system/cpu/cpu4/cpufreq/scaling_max_freq 
1800000
  • All of 8 cores are ON
  • Script
#!/bin/sh

echo "Temp, FreqCPU0, FreqCPU4, FreqCPU5, Freq6CPU, FreqCPU7 "
while true :
do
     t=`cat /sys/devices/virtual/thermal/thermal_zone0/temp`
     t1=$(( $t/1000))

     f0=`cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq`
     f0_r=$(( $f0/100000))

     f4=`cat /sys/devices/system/cpu/cpu4/cpufreq/scaling_cur_freq`
     f4_r=$(( $f4/100000))

     f5=`cat /sys/devices/system/cpu/cpu5/cpufreq/scaling_cur_freq`
     f5_r=$(( $f5/100000))

     f6=`cat /sys/devices/system/cpu/cpu6/cpufreq/scaling_cur_freq`
     f6_r=$(( $f6/100000))

     f7=`cat /sys/devices/system/cpu/cpu7/cpufreq/scaling_cur_freq`
     f7_r=$(( $f7/100000))

     echo $t1, $f0_r, $f4_r, $f5_r, $f6_r, $f7_r

     sleep 2

Test Case 1 - Max CPU Frequency 2.0GHz case

Here is sysbench test result in case of max cpu frequency 2.0GHz.

  • Running Time : about 1.16% increase - XU4Q / XU4 = 420 / 362 = 1.16%
  • Average CPU Frequency : about 0.78% loss - XU4Q / XU4 = 1.48 / 1.89 = 0.78%

Test Case 2 - Max CPU Frequency 1.8GHz case

  • Running Time : about 1.06% increase - XU4Q / XU4 = 392 / 368 = 1.06%
  • Average CPU Frequency : about 0.89% loss - XU4Q / XU4 = 1.61 / 1.8 = 0.89%

Test Case 3 - Finding the threshold not to drop under max frequency
