It would have been easy to believe that the NASA Perseverance Rover would have some current-generation CPU fueling it, but quite the contrary. According to the latest report, the Rover is actually powered by the same processor that was found in the 1998 iMac, a machine released more than two decades ago.

For those wondering, the processor that powered both the Perseverance Rover and the 1998 iMac is the PowerPC 750. Looking at how modern processors have developed and advanced, the PowerPC 750 will be a sloth compared to desktop, laptop, and even smartphone chips. If you still need a little jolt to your memory concerning which machine used back in the 90s, it was the iMac G3, which featured an entire computer inside its colorful enclosure.
