Reviews for the Asus ZenBook S UX391U

88.5% Asus ZenBook S UX391U (Core i7, FHD) Laptop Review | Notebookcheck
The ZenBook S (UX391) is a particularly light 13.3-inch laptop from Asus. It tips the scale at just 1 kg, but the manufacturer says the performance is not affected. We review the rival for the XPS 13.
60% Asus ZenBook S review: S is for Style, not for Substance
Source: It Pro English
Although the Asus ZenBook S is speedy enough to satisfy, and it looks the absolute business, there are too many flaws to recommend it, including a disappointing screen and some serious thermal issues.

80% ASUS ZenBook S review: Just a decent laptop
Source: Engadget English
If you’re in the market for a traditional Windows laptop that won’t weigh you down, the ZenBook S is a solid choice. Despite its small size, it has enough power for most tasks. Battery life is a letdown, but the S is still a good option unless you need to be unplugged for a full workday at a time.

Asus Zenbook S first look – A ‘military grade’ Macbook rival

The Zenbook S doesn’t have the wow factor of Asus’ other Computex releases, but from what I’ve seen it looks like a solid, ultraportable Macbook rival.

Hands on: Asus ZenBook S review
Source: Techradar English
The Asus ZenBook S isn’t the world’s thinnest, most affordable or even a 100% uniquely designed laptop, but it still looks like the Ultrabook to treat yourself with right now.

Asus ZenBook S is the laptop you’ll actually want on your lap
Source: CNet English
Inside, the ZenBook S is packing some pretty premium specs in that thin body, including a 13.3-inch 4K display, Intel Core i7 processor, 16GB of RAM and a 1TB SSD on the top-of-the-line model.

Intel UHD Graphics 620: Integrated GPU (GT2, 24 EUs) found on some Kaby-Lake-Refresh CPU models (15 W ULV series). Technically identical to the previous Kaby-Lake GPU called HD Graphics 620. Modern games should be playable with these graphics cards at low settings and resolutions. Casual gamers may be happy with these cards. » Further information can be found in our Comparison of Mobile Graphics Cards and the corresponding Benchmark List.
Intel Core i7: The Intel Core i7 for laptops is based on the LG1156 Core i5/i7 CPU for desktops. The base clock speed of the CPUs is relatively low, but because of a huge Turbo mode, the cores can dynamically overclock to up to 3.2 GHz (920XM). Therefore, the CPU can be as fast as high clocked dual-core CPUs (using single threaded applications) but still offer the advantage of 4 cores. Because of the large TDP of 45 W / 55 W, the CPU is only intended for large laptops.  
8550U: Kaby-Lake-Refresh based low power quad-core processor. The four cores are clocked between 1.8 and 4 GHz (Turbo Boost) and support HyperThreading. The integrated GPU is clocked between 300 and 1,150 MHz. The SoC is manufactured in a 14nm+ FinFET process.» Further information can be found in our Comparison of Mobile Processsors.
13.3":

Above all, this display size is used for subnotebooks, ultrabooks and convertibles. For all three types, this size is quite large. The biggest variety of subnotebooks is represented with this size.

Large display-sizes allow higher resolutions. So, details like letters are bigger. On the other hand, the power consumption is lower with small screen diagonals and the devices are smaller, more lightweight and cheaper.

1.018 kg:

This weight is typical for big tablets, small subnotebooks, ultrabooks and convertibles with a 10-11 inch display-diagonal.


Asus: ASUSTeK Computer Incorporated, a Taiwanese multinational company, produces motherboards, graphics cards, optical drives, PDAs, computer monitors, notebook computers, servers, networking products, mobile phones, computer cases, computer components, and computer cooling systems. The company's 2007 revenues reached US$6.9 billion. ASUS also produces components for other manufacturers. The Eee PC initiated the netbook boom in 2008.

In the notebook sector, Asus had a global market share of about 11% from 2014-2016, making it the fourth largest laptop manufacturer. In the smartphone sector, Asus is not among the Top 5 and has only a small market share (as of 2016).


82.21%: This rating should be considered to be average. This is because the proportion of notebooks which have a higher rating is approximately equal to the proportion which have a lower rating.
