A big surprise for many is the Perseverance Mars rover, the most advanced rover mankind has ever created - weaker (in terms of processing power) than most smartphones. At the core of Perseverance is an old chipset that gives it the computing power of the 1998 iMac. Specifically, it has only 256 MB of RAM and 2 GB of permanent memory, and the frequency of its processor is only 200 MHz.
For comparison, the original Apple Watch is charged with 512MB of RAM and 8GB of storage, and its processor is clocked at 520MHz. But the trick is that NASA engineers know exactly what they are doing. They use time-proven components to provide the rover with maximum reliability. After all, if any trouble happens to the Perseverance stuffing, the nearest computer workshop is several tens of millions of kilometers away.
Unlike previous rovers, Perseverance carries a novelty - the first ever Martian helicopter. It is powered by the equally archaic Qualcomm Snapdragon 801 processor. Such CPUs could be found in smartphones that were produced in the mid-2010s, such as the Samsung Galaxy S5, LG G3, or HTC One M8. This means a funny thing - the smartphone in your pocket is most likely more powerful than the most advanced rover on our planet.
For the sake of fairness, it should be noted that although the Perseverance computer filling is very ancient, the equipment that runs on it, on the contrary, is very advanced. The rover is equipped with 23 cameras that are used for navigation and mineral analysis, as well as powerful communication systems for transmitting data back to Earth.
