How do you possibly justify putting 254 teraflops(?) to work for an infotainment system? You can display 1080p video with a mere hundredth of that power. It's not so significant in the big scheme of things, but that sounds to me like the operating system could be less than ideal, and that Mercedes are just throwing silicon at the problem in an attempt to compensate.
Hopefully there has just been mix up and that processing power is going towards more gainful activities like automatic lane-keeping.
