Lots of space stuff is 10-20 years behind what we use on the ground because of radiation hardening. Both because volume is so low that radiation hardened electronics have a very slow update schedule, and because older technology is inherently more radiation tolerant (higher voltages, larger process nodes, etc).
The ISS has off-the-shelf notebooks, but apart from that the uptake of regular non-hardened hardware is relatively recent and quite slow. I think the Falcon 9 has a couple non-hardened systems, and of course Ingenuity has lots of regular off-the-shelf hardware. That was one of the big reasons the predicted lifespan of Ingenuity was so low, but software mitigations (like the ability to reboot mid-flight) have proven very effective.
