Instead of being announced at Computex, the new ZenBook 14 Flip powered by AMD's Ryzen 5 3500U only made a discrete appearance on Amazon France. Besides the AMD CPU that is integrating a Radeon RX Vega 8 GPU, the refreshed model comes with a thin bezel touchscreen and a smaller battery that makes it lighter than the Intel-powered versions.

Asus Malaysia announced this five days ago.
