Prompted by news of Sandia National Labs' SA3000 8085 CPU, a recent discussion explored the current landscape of radiation-hardened processors used in aerospace and space applications. Commentators noted that state-of-the-art rad-hard chips from companies like MOOG and BAE utilize IBM POWER architecture, while specialized system-on-chips from AMD are actively engineered for radiation tolerance. The conversation also clarified a common misconception, emphasizing that standard commercial desktop and server processors do not inherently possess the specific engineering required to withstand harsh space environments.
