What Makes a CPU "Rugged"?
A rugged CPU is not a special silicon part — it is a standard processor (typically Intel® Celeron®, Intel® Core™ or ARM-based) paired with a chassis, cooling design and power stage engineered to survive conditions that would quickly end the life of an office desktop. Ruggedness lives in the system around the processor: a fanless passively cooled enclosure, wide-temperature-rated components, protection against dust and vibration, wide-range DC power input, and firmware features such as watchdog timers and auto-restart on power failure. When people search for a "rugged CPU", they usually need a fanless industrial PC that can run 24/7 in a factory, a kiosk, a vehicle or an outdoor cabinet.
