A new Chromebook featuring APUs from AMD's Picasso range of processors might be in the works. A device with the codename "Zork" has been unearthed that apparently utilizes a Chrome OS board called "Trembyle". Data management commits have been spotted that link Zork with Picasso – which means a Chromebook with an AMD Ryzen 5 3500U inside could be in development.
