Turns out the processor executes 1.2 billion instructions per second, 400 million per core. Still not a whirlwind I would guess, but better than the number I quoted. Apparently, it's one of the most powerful -- and perhaps the most powerful -- for an automotive infotainment system. There will be a development kit abd app store, but Cadillac will approve all apps.
