BIGTREETECH CB1（H616）和 树莓派4B CPU对比测试

[newcastle]

一，实物对比图：
BIGTREETECH CB1的底板接口的分布和树莓派4B是一样的，但是没有树莓派的音频接口，底板也不能放到树莓派4B的官方外壳里，因为底板的背面有一个DSI接口，高度超出了。

二，开发板硬件配置对比
可以看出H616为4核A53@1.5G，树莓派4B为4核A72@1.5G，树莓派4B的CPU规格略高一些，但它俩都是28nm制程工艺。

三，CPU规格对比：
这个上一个ARM官网的对比图。

四，室温下CPU温度对比
使用命令
cat /sys/class/thermal/thermal_zone0/temp | awk '{print $1/1000}'

五，lscpu命令对比

其中可以看到H616的BogoMIPS是48，树莓派4B的BogoMIPS是108。

何为BogoMIPS，MIPS是millions of instructions per second(百万条指令每秒)的缩写，其代表CPU的运算速度，是cpu性能的重要指标。但只能用来粗略计算处理器的性能，并不十分精确。

六，专业软件对比CPU

这里我们使用Sysbench这个软件来测试2款CPU的性能。

Sysbench是一个开源的、模块化的、跨平台的多线程性能测试工具，可以用来进行CPU、内存、磁盘I/O、线程、数据库的性能测试。

安装使用命令 sudo apt-get install sysbench
测试CPU命令 sysbench cpu run

biqu@Hurakan:~$ sysbench cpu run
sysbench 1.0.20 (using system LuaJIT 2.1.0-beta3)

Running the test with following options:
Number of threads: 1
Initializing random number generator from current time


Prime numbers limit: 10000

Initializing worker threads...

其中CPU speed: events per second:CPU速度：每秒完成数 是衡量CPU速度的指标，可以看到在单线程下，BIGTREETECH CB1是502.85，树莓派4B是1483.27。

总结：通过对2种开发板CPU进行各种对比，可以发现H616和树莓派4B在CPU性能上还是有一定差距的。
