The ASUS ZenBook notebook series with AMD 15 Watt Ryzen 7 3700U Mobile or Ryzen 5 3500U Mobile and integrated Radeon Vega graphics currently include three models:
All ASUS ZenBook systems based on AMD Ryzen Mobile APU feature a 14-inch InfinityEdge Full HD Screen with or without touch support that includes 100% of the sRGB color gamut. While all cellular PCs have thin frames, the UM433DA seems to have the thinnest frame while the UM431DA is the thickest. Meanwhile, the ZenBook Flip 14 UX462DA maintains a natural touch, works with AS Pen (1024 compression level, 10-300 gram pen strength, Windows ink, etc.) and features a corporate 360 degree ErgoLift hinge
The interior of the ZenBook 14 UM431DA, ZenBook 14 UM433DA and ZenBook Flip 14 UX462DA is based on AMD Ryzen Mobile 3000 quad-core APUs with integrated Radeon Vega graphics combined with DDR4-2400 8GB to 16GB memory and SSDs from 256 GB to 1 TB (see specifications exactly in the following table). Out of curiosity (maybe for cost reasons), ASUS decided to use SATA or PCIe 3.0 x2 SSD for most SKUs. Only the most expensive 1 TB SSD has a complete PCIe 3.0 x4 interface.
In terms of connectivity, we have standard 802.11ac Wi-Fi, Bluetooth, USB Type-A and USB Type-C ports, HDMI monitor output and a 3.5mm audio jack. Meanwhile, only UM433DA supports USB 3.1 Gen 2, although the AMD mobile platform fully supports the technology.
The ZenBook 14 UM431DA and ZenBook 14 UM433DA battery life comes with 47 and 50 Wh batteries, all of which are designed for up to 12 hours of battery life. Instead, the ZenBook Flip 14 UX462DA is equipped with a 42 Wh battery, which is designed for 9 hours.
