If you are planning to buy a notebook, there are a couple of questions you need to answer before you make a decision. First, what do you need your laptop for? Are you going to play games on it, use it as a workhorse, or just for multimedia consumption? Then, you need to figure out your budget.
So, if you are in school, work from home, or just want to express yourself, one of the best options is the VivoBook series. And if you are planning to invest a bit more – the ZenBook, also from ASUS. However, if your budget is tight, but you still want something of good quality, then the ASUS VivoBook S-series fall right into your target group of devices.
Even though the VivoBook was always about compromises, this year, ASUS has other plans. Introducing, the VivoBook S14 S435 with all-metal chassis, and Tiger Lake CPUs. In addition to that, the laptop is part of the Evo platform, which ensures high performance and good efficiency.
Not in the last place, the manufacturer is promising that the 14-inch display will cover 100% of the sRGB color gamut, and will have 400 nits of brightness. Not bad at all, provided these claims are accurate.

ASUS VivoBook S14 (S435) - Specs
What’s in the box?
Inside this notebook’s packaging, you will find some paper manuals, a 65W USB Type-C power brick, as well as a cool bag.
Design and construction
For the first time, we see a VivoBook with an all-metal design. That’s right, the VivoBook S14 S435 is made out of aluminum, with “diamond cut” chamfered edges. It looks and feels really solid, thus appearing like a ZenBook in disguise. Thankfully, the laptop is both thin and light, as it measures 15.9mm in profile and weighs only 1.30 kg. After all, the competition has gone far, so ASUS had to step up their game.
Interestingly, even the lid opens with a single hand, as the hinges feel smooth up until the 90-100° mark. Here, the display has a matte finish and is surrounded by pretty slim bezels, for an alleged screen-to-body ratio of 90%. Additionally, you can see an HD Web camera – a feature that has become somewhat mandatory in the past year.
As we said, the laptop is structurally sound, although there is a very slight observable flex, when we twist the notebook. As far as the keyboard goes, we can confidently say, that it is comfortable to use. This is thanks to the decent key travel and the clicky feedback. Also, it has a backlight. If you look closely, you will see the signature Enter key that has a yellow accent around it. Here, the only disadvantage we found was the size of the Arrow keys.
Moving to the touchpad, we get a glass-covered surface, which delivers a decent gliding experience. Its tracking is great, and the clicking mechanism is on point. In fact, it registers a click in pretty much every point of the surface. By the way, this device also supports ASUS’s NumberPad. It can be enabled by holding your finger on the top right corner for 1 second. Respectively, the shortcut on the top left corner launches the Calculator app by swiping and toggles between two brightness settings when held. By the way, there is a fingerprint reader, as well, and it is located on the left part of the palm rest area.
If you turn the laptop upside down, you will notice the speaker cutouts. Interestingly, the tiny ventilation grill is placed in the opposite corner to the fan, while the hot air is pushed away from a grill in between the lid and the base. Actually, we are pretty confident that the fan draws some of the air through the keyboard, but the rest is sucked from the vent on the bottom panel. This takes some of the heat away from the VRM modules, and the SSD, which is good. On the other hand, this means that warmer air enters the fan, hindering the overall cooling capacity. Nevertheless, we will see the efficiency of this setup in the “Temperatures and comfort” portion of this review.
On the left side, you will find two Thunderbolt 4 connectors, an HDMI 1.4 connector, and an audio jack. Switch the laptop around, and you’ll see a USB Type-A 3.2 (Gen. 1) port, a USB Type-A 2.0 port, and a MicroSD card slot.
Disassembly, upgrade options and maintenance
This laptop’s bottom panel is held in place by 9 Torx-head screws. After you undo them, you need to pry the panel with a plastic tool. Then, lift it away from the chassis.
It’s good to see that ASUS has integrated a 67Wh battery pack inside of this machine.
Sadly, but expectedly, the memory is soldered to the motherboard. However, the configurations available include 8 and 16GB of LPDDR4x RAM. Thankfully, the storage can be upgraded via one M.2 PCIe x4 slot.
Now, the cooling solution looks pretty typical for a laptop of this class. It has a pretty beefy heat pipe, a heat sink, and a fan, which has a rather slim profile. However, ASUS state that their fan blades have a 3D-curved design, whatever this means.
ASUS VivoBook S14 S435’s main display has a touchscreen Full HD panel, model number AUO B140HAN06.B (AUOA48F). Its diagonal is 14″ (35.56 cm), and the resolution – 1920 х 1080. Additionally, the screen ratio is 16:9, the pixel density – 157 ppi, their pitch – 0.161 x 0.161 mm. The screen can be considered Retina when viewed from at least 55 cm (from this distance, the average human eye can’t see the individual pixels).
It has comfortable viewing angles. We have provided images at 45 degrees to evaluate quality.
The maximum measured brightness is 380 nits (cd/m2) in the middle of the screen and 384 nits (cd/m2) average across the surface with a maximum deviation of 9%. The Correlated Color Temperature on a white screen and at maximum brightness is 6520K (average) – matching the 6500K optimum for sRGB.
In the illustration below you can see how the display performs from a uniformity perspective.
Values of dE2000 over 4.0 should not occur, and this parameter is one of the first you should check if you intend to use the laptop for color-sensitive work (a maximum tolerance of 2.0 ). The contrast ratio is very good – 1590:1.
To make sure we are on the same page, we would like to give you a little introduction to the sRGB color gamut and the Adobe RGB. To start, there’s the CIE 1976 Uniform Chromaticity Diagram that represents the visible specter of colors by the human eye, giving you a better perception of the color gamut coverage and the color accuracy.
Inside the black triangle, you will see the standard color gamut (sRGB) that is being used by millions of people on HDTV and on the web. As for the Adobe RGB, this is used in professional cameras, monitors, etc for printing. Colors inside the black triangle are used by everyone and this is the essential part of the color quality and color accuracy of a mainstream notebook.
Still, we’ve included other color spaces like the famous DCI-P3 standard used by movie studios, as well as the digital UHD Rec.2020 standard. Rec.2020, however, is still a thing of the future and it’s difficult for today’s displays to cover that well. We’ve also included the so-called Michael Pointer gamut, or Pointer’s gamut, which represents the colors that naturally occur around us every day.
The yellow dotted line shows ASUS VivoBook S14 S435’s color gamut coverage.
Its display covers 98% of the sRGB/ITU-R BT.709 (web/HDTV standard) in CIE1976.
Our “Design and Gaming” profile delivers optimal color temperature (6500K) at 140 cd/m2 luminance and sRGB gamma mode.
We tested the accuracy of the display with 24 commonly used colors like light and dark human skin, blue sky, green grass, orange, etc. You can check out the results at factory condition and also, with the “Design and Gaming” profile.
Below you can compare the scores of ASUS VivoBook S14 S435 with the default settings (left), and with the “Gaming and Web design” profile (right).
The next figure shows how well the display can reproduce dark parts of an image, which is essential when watching movies or playing games in low ambient light.
The left side of the image represents the display with stock settings, while the right one is with the “Gaming and Web Design” profile activated. On the horizontal axis, you will find the grayscale, and on the vertical axis – the luminance of the display. On the two graphs below you can easily check for yourself how your display handles the darkest nuances but keep in mind that this also depends on the settings of your current display, the calibration, the viewing angle, and the surrounding light conditions.
Response time (Gaming capabilities)
We test the reaction time of the pixels with the usual “black-to-white” and “white-to-black” method from 10% to 90% and vice versa.
We recorded Fall Time + Rise Time = 31 ms
After that, we test the reaction time of the pixels with the usual “Gray-to-Gray” method from 50% White to 80% White and vice versa between 10% and 90% of the amplitude.
Health impact – PWM / Blue Light
PWM (Screen flickering)
Pulse-width modulation (PWM) is an easy way to control monitor brightness. When you lower the brightness, the light intensity of the backlight is not lowered, but instead turned off and on by the electronics with a frequency indistinguishable to the human eye. In these light impulses, the light/no-light time ratio varies, while brightness remains unchanged, which is harmful to your eyes. You can read more about that in our dedicated article on PWM.
The light coming from ASUS VivoBook S14 S435’s backlight does not flicker. This makes it comfortable for use during long periods, without harming your eyes in this aspect.
Blue light emissions
Installing our Health-Guard profile not only eliminates PWM but also reduces the harmful Blue Light emissions while keeping the colors of the screen perceptually accurate. If you’re not familiar with the Blue light, the TL;DR version is – emissions that negatively affect your eyes, skin, and your whole body. You can find more information about that in our dedicated article on Blue Light.
ASUS VivoBook S14 S435’s IPS panel has a Full HD resolution, decent maximum brightness, a very good contrast ratio, and comfortable viewing angles. This particular panel, which is the same as that of the ASUS ZenBook Duo 14 UX482, covers 98% of the sRGB gamut. It doesn’t use PWM and can be used for professional work. Especially with our Gaming and Web design profile, which delivers standard-matching color accuracy.

In addition to receiving efficient and health-friendly profiles, by buying LaptopMedia's products you also support the development of our labs, where we test devices in order to produce the most objective reviews possible.
Office Work should be used mostly by users who spend most of the time looking at pieces of text, tables or just surfing. This profile aims to deliver better distinctness and clarity by keeping a flat gamma curve (2.20), native color temperature and perceptually accurate colors.
Design and Gaming
This profile is aimed at designers who work with colors professionally, and for games and movies as well. Design and Gaming takes display panels to their limits, making them as accurate as possible in the sRGB IEC61966-2-1 standard for Web and HDTV, at white point D65.
Health-Guard eliminates the harmful Pulse-Width Modulation (PWM) and reduces the negative Blue Light which affects our eyes and body. Since it’s custom tailored for every panel, it manages to keep the colors perceptually accurate. Health-Guard simulates paper so the pressure on the eyes is greatly reduced.
ASUS VivoBook S14 S435’s speakers are tuned by Harman Kardon. They produce a sound with very good quality, as its low, mid, and high tones are clear of deviations.

Now, we conduct the battery tests with Windows Better performance setting turned on, screen brightness adjusted to 120 nits, and all other programs turned off except for the one we are testing the notebook with. Here, the 67Wh battery delivers 13 hours and 20 minutes of Web browsing, and 14 hours and 10 minutes of video playback.
In order to simulate real-life conditions, we used our own script for automatic web browsing through over 70 websites.
For every test like this, we use the same video in HD.
We use F1 2017’s built-in benchmark on loop in order to simulate real-life gaming.
There are two configurations, depending on the processor. They come with either the Core i5-1135G7 or the Core i7-1165G7.
Results are from the Cinebench 20 CPU test (the higher the score, the better)
Results are from the Fritz chess benchmark (the higher the score, the better)
Results are from our Photoshop benchmark test (the lower the score, the better)
Respectively, the only graphics option is the integrated Iris Xe Graphics G7 with either 80 or 96 EUs. Given its potential, though, you shouldn’t be disappointed.
Results are from the 3DMark: Fire Strike (Graphics) benchmark (higher the score, the better)
Results are from the Unigine Heaven 3.0 benchmark (higher the score, the better)
Results are from the Unigine Heaven 4.0 benchmark (higher the score, the better)
Results are from the Unigine Superposition benchmark (higher the score, the better)

For some reason, the Performance preset didn’t really work with Prime95. In situations where the fan was blowing its life out in Cinebench R20, it was almost silent in Prime95 stress-testing. Still, with the fan barely spinning, it managed to maintain 20W and a frequency of about 2.00 GHz at the end of the test.
Comfort during full load
Because of the low fan RPM, we monitored high external temperatures, going at about 47°C.
Before we started this review, we were not really sure what to compare it with. Given the fact that the VivoBook brand was not really known for its high-quality builds, nor its supreme battery life, we expected to see a budget all-rounder intended mainly for multimedia consumption and school work. However, once we have taken it into our hands, our perception of the S14 S435 changed dramatically.
Not only did it look and feel premium, but it scored well in pretty much all of our tests. This includes the performance, where it was more than decent. After all, ASUS claims that their laptop can maintain the higher (28W) TDP limit of the processor inside. Although it was a bit less, we were happy with the stability of the performance, as every run of the Cinebench R20 benchmark produced the same results (plus or minus).
Also, ASUS VivoBook S14 S435’s IPS panel (AUO B140HAN06.B (AUOA48F)) has a Full HD resolution, decent maximum brightness, a very good contrast ratio, and comfortable viewing angles. This particular panel, which is the same as that of the ASUS ZenBook Duo 14 UX482, covers 98% of the sRGB gamut. It doesn’t use PWM and can be used for professional work. Especially with our Gaming and Web design profile, which delivers standard-matching color accuracy.
This means that a VivoBook can be used for professional work. By professionals. Can you imagine? This puts it as a possible alternative to the MacBook Air (M1, late 2020). Even the battery life was good – 13 hours and 20 minutes of Web browsing, and 14 hours and 10 minutes of video playback.
Yes, we know how absurd it is to compare it to a MacBook but there is an area where it actually beats it – the I/O. In addition to the two Thunderbolt 4 connectors, you get an HDMI connector, two USB Type-A ports (although one only reaches 2.0 speeds), and a MicroSD card slot. Also, the presence of Wi-Fi 6 means you can reach Ethernet speeds, provided you have an appropriate router.
On the other side, the soldered memory might be a bit of an issue in the long run, especially if you opt for the 8GB version of the device. But considering the competition, and the lack of memory upgradability of pretty much all ultrabooks out there (something that we don’t endorse), the VivoBook S14 S435 is easy to recommend.
