ASUS has quietly added three ZenBooks based on AMD’s Ryzen Mobile 3000-series APUs to its lineup. One of the machines is a convertible ZenBook Flip 14, the other two are traditional ZenBook 14 notebooks. All three mobile PCs offer what you come to expect from ZenBook-branded laptops: stylish design, sleek aluminum chassis, high performance components, robust connectivity, and various premium features like Harman Kardon-badged audio or a NumberPad touchpad.

The lineup of ASUS ZenBook notebooks powered by AMD’s 15 Watt Ryzen 7 3700U Mobile or Ryzen 5 3500U Mobile with integrated Radeon Vega graphics currently includes three models: the relatively basic ZenBook 14 UM431DA, the more premium ZenBook 14 UM433DA, and the convertible ZenBook Flip 14 UX462DA.

All the ASUS ZenBook systems based on AMD’s Ryzen Mobile APUs feature a 14-inch InfinityEdge Full-HD display with or without touch support that cover 100% of the sRGB color gamut. While all of the mobile PCs feature thin bezels, the UM433DA seems to feature the thinnest bezels, whereas the UM431DA has the thickest. Meanwhile, the ZenBook Flip 14 UX462DA naturally supports touch, can work with the ASUS Pen (1024 pressure levels, 10-300 grams pen-tip force, Windows Ink, etc.), and features the company’s 360-degree ErgoLift hinge

When it comes to internals of the ZenBook 14 UM431DA, ZenBook 14 UM433DA, and ZenBook Flip 14 UX462DA, they are all powered by AMD’s quad-core Ryzen Mobile 3000-series APUs with integrated Radeon Vega graphics that are paired with 8 to 16 GB of DDR4-2400 memory as well as an SSD ranging from 256 GB to 1 TB (see exact specs in the table below). In a curious move (perhaps for cost-cutting reasons) ASUS decided to use SATA or PCIe 3.0 x2 SSDs on most SKUs; only the most expensive 1 TB SSD features a full PCIe 3.0 x4 interface.

From connectivity standpoint, we have a fairly standard machines with 802.11ac Wi-Fi, Bluetooth, USB Type-A and USB Type-C connectors, an HDMI display output, and a 3.5-mm audio jack. Meanwhile, only the model UM433DA supports USB 3.1 Gen 2 despite the fact that AMD’s mobile platform fully supports the technology.

As far as battery life is concerned, the ZenBook 14 UM431DA and the ZenBook 14 UM433DA are equipped with 47 Wh and 50 Wh batteries rated for up to 12 hours of work on one charge. By contrast, the convertible ZenBook Flip 14 UX462DA comes with a 42 Wh battery rated for 9 hours.
