San Francisco, Aug 31 (IANS): Taiwanese electronics major ASUS on Friday launched "ZenBook 13" (UX333), "ZenBook 14" (UX433) and "ZenBook 15" (UX533).

The new redesigned series of thin and light laptops also mark the debut of a frame-less "NanoEdge" display with ultraslim bezels on all four sides and up to 95 per cent screen-to-body ratio.

All devices are torture-tested to military-grade reliability standards, with demanding tests that include environmental extremes of altitude, temperature and humidity, in addition to extensive drop, shock and vibration testing, the company said in a statement.

The 13-inch and 14-inch models also include the new "NumberPad", an innovative productivity enhancement that provides a full-size LED-illuminated numeric keypad built into the touchpad.

All models feature a special 3D IR camera that allows fast face login using Windows Hello, even in low-light environments, the company added.

The new models come with 8th Generation Intel Core i7 quad-core CPU, NVIDIA GeForce GTX 1050 Max-Q graphics, 16GB RAM, ultra-fast PCIe SSDs and gigabit-class Wi-Fi.
