【FireBeetle 2 ESP32 C6】几种esp32性能对比测试
<p>为了了解esp32c6的性能，在手上的几个开发板上，做了一个简单的性能对比。编写了一小段测试程序，分别计算分形、圆周率等。测试不是太严谨，只作为一个参考。</p><p> </p>
<p>从左到右分别是：rpi PICO、esp32s2、esp32s3、esp32c3、esp32c6，硬件方面的对比请参考<a href="https://bbs.eeworld.com.cn/thread-1279701-1-1.html">【FireBeetle 2 ESP32 C6】esp32系列芯片对比 </a>这个帖子。</p>
<p> </p>
<p> </p>
<p> </p>
<p>测试程序如下，包括了加法、乘法（除法）、分形、圆周率等计算程序，分别计算每项测试所用的时间，时间越短代表性能越好。为了保证在相同的环境下进行测试，在测试前，将开发板的固件都升级到最新的测试版本。</p>

<p>从测试结果可以看到，esp32c6在性能上，相比esp32c3略有提升，综合起来有5-10%左右。几种esp32芯片的性能差异都不算太大，但risc-v内核的esp32cx系列还是略有优势。这样看起来，后续的H系列（低成本低功耗无线通信）和P系列（高性能高安全通用型）也会比较值得期待。</p>

<p>楼主总结的esp32性能对比内容非常实用，对挑选板子非常具有参考价值，感谢楼主的分享</p>
<p>esp32c3到esp32c6，为什么中间跨度这么大？ </p>
