If you're remembering correctly, then I'm misremembering in that this has essentially a Snapdragon chip and not a rad hardened CPU at all

They used the hardened PowerPC for the rover, similar to previous mars rovers and the Snapdragon chip for the helicopter.

Maybe I am misremembering the interview. Maybe the person said that they used to use a hardened IBM power chip?

This information is pretty widely available, e.g. on Wikipedia [1], no need to go off memory. Flight control is done by an FPGA, the main CPU is a Snapdragon 801 running Linux, and it uses Zigbee to communicate with the rover.

At least they won't have any trouble finding a free channel.
