It stopped being about reliability twenty years ago. Now it's about lining pockets. The current top of the line RAD5545 is based on a chip from 2010 with 45nm lithography. It consumes 20 watts to perform 3.7GFLOPS. A Snapdragon 8 Gen 3 has a TDP of 12w and does 4.7TFLOPS. Over a thousand times the performance at less than a thousandth the price.

Rather, they're turning to other options to achieve rad tolerance in critical systems, stuff like soft cores specifically designed for redundancy running on radiation hardened FPGAs. Also, the rad tolerant parts aren't there to do the crazy high speed work. When people talk about voting architectures with redundant COTS parts, what do you think is counting the votes and resetting the effected systems?
