Benchmark of XU4 with Active Cooler and XU4Q with Passive Cooler

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.

• 1. Thermal and Frequency Performance Comparison
• 2. AnTuTu Performance Comparison
• 3. Kernel Build Time Performance Comparison

We've tested three categories of benchmarking utilities and here is a brief result for each test cases.

sysbench
- to investigate and compare thermal/cpu frequency performance
- Sysbench running time increased by 16% and 6% for each cases of cpu max 2GHz and 1.8GHz
AnTuTu
- for examining a variety of categories performance
- The decreasing score value of XU4Q from XU is just 2%
Kernel build
- to check the hardest stress case
- About 5m 17s increase of the total execution time (20%)

Except the hardest case like kernel build, the differences are under just 10% or lower.

• 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

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

• Running Time : about 16% increase - XU4Q / XU4 = 420 / 362 = 116%
• Average CPU Frequency : about 22% loss - XU4Q / XU4 = 1.48 / 1.89 = 78%

• Running Time : about 6% increase - XU4Q / XU4 = 392 / 368 = 106%
• Average CPU Frequency : about 11% loss - XU4Q / XU4 = 1.61 / 1.8 = 89%

Here is Android AnTuTu benchmark result for examining common and a variety of categories' score.

OS - LineageOS-14.1 Android 7.1.1 Nougat
Resolution - 1280×720
The benchmark has been tested at twice.

ODROID-XU4


ODROID-XU4Q

To check the hardest stress case, we did put kernel build test on XU4 and XU4Q.
The test instruction is as following.

$ make odroidxu3_defconfig
$ time make -j8

Based on the result, in this case, the kernel build time on XU4Q gets around 20% increase from XU4's one.
