Server CPU's: great margin, but Arm64 eating their lunch. Low Power: lamer products. Mobile: a nobody. Embedded: a nobody. Salesforce: spoiled by margins/device. They have their shareholders breathing down their neck to make a showing, *any showing* in embedded land. What you are seeing here is the result of desparately trying to make that showing by slapping together whatever they found in the drawer That shows too - it's a rude joke for realtime control; it will make a great heater control though.
