NASA’s <em>Perseverance</em> rover operates on a <strong>BAE Systems RAD750</strong> processor. It is a <em>Rad-Hard</em> component (resistant to ionizing radiation) based on PowerPC architecture from the late 90s, with a clock speed of just <strong>200 MHz</strong>. To put it brutally: your smartphone chip is hundreds of times faster.</p> <!-- /wp:paragraph --></div> <!-- /wp:column --></div>
