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。
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 $1/1000}'
五,lscpu命令对比 其中可以看到H616的BogoMIPS是48,树莓派4B的BogoMIPS是108。 何为BogoMIPS,MIPS是millions of instructions per second(百万条指令每秒)的缩写,其代表CPU的运算速度,是cpu性能的重要指标。但只能用来粗略计算处理器的性能,并不十分精确。 六,专业软件对比CPU 这里我们使用Sysbench这个软件来测试2款CPU的性能。 Sysbench是一个开源的、模块化的、跨平台的多线程性能测试工具,可以用来进行CPU、内存、磁盘I/O、线程、数据库的性能测试。 安装使用命令 sudo apt-get install sysbench
测试CPU命令 sysbench cpu runbiqu@Hurakan:~$ sysbench cpu runsysbench 1.0.20 (using system LuaJIT 2.1.0-beta3)Running the test with following options:Number of threads: 1Initializing random number generator from current timePrime numbers limit: 10000Initializing worker threads...Threads started!CPU speed: events per second: 502.43General statistics: total time: 10.0008s total number of events: 5028Latency (ms): min: 1.98 avg: 1.99 max: 2.19 95th percentile: 2.00 sum: 9995.01Threads fairness: events (avg/stddev): 5028.0000/0.00 execution time (avg/stddev): 9.9950/0.00biqu@Hurakan:~$ sysbench cpu runsysbench 1.0.20 (using system LuaJIT 2.1.0-beta3)Running the test with following options:Number of threads: 1Initializing random number generator from current timePrime numbers limit: 10000Initializing worker threads...Threads started!CPU speed: events per second: 502.85General statistics: total time: 10.0005s total number of events: 5032Latency (ms): min: 1.98 avg: 1.99 max: 2.20 95th percentile: 2.00 sum: 9995.15Threads fairness: events (avg/stddev): 5032.0000/0.00 execution time (avg/stddev): 9.9951/0.00biqu@Hurakan:~$ tage@raspberrypi:~ $ sysbench cpu runsysbench 1.0.20 (using system LuaJIT 2.1.0-beta3)Running the test with following options:Number of threads: 1Initializing random number generator from current timePrime numbers limit: 10000Initializing worker threads...Threads started!CPU speed: events per second: 1483.27General statistics: total time: 10.0005s total number of events: 14840Latency (ms): min: 0.67 avg: 0.67 max: 1.81 95th percentile: 0.68 sum: 9994.28Threads fairness: events (avg/stddev): 14840.0000/0.00 execution time (avg/stddev): 9.9943/0.00tage@raspberrypi:~ $
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。
