Asus VivoBook S15 evaluate

Why is it solely 14-inch and smaller laptops get the slim and light-weight therapy? Search for one thing with a 15-inch display and also you’ll principally discover efficiency machines or normal laptops you wouldn’t need to carry round or take out in public too typically.

The Asus VivoBook S15 is a 15-inch laptop computer that’s gentle, slim and engaging. And it’s not too costly both.

This laptop computer’s construct isn’t near Asus’s finest ZenBooks, although, so ensure you maintain your expectations in verify.

Value and availability

The Asus VivoBook S15 covers the vary of Intel Core i-series processors. In case you’re proud of a Core i3, which might be extra highly effective than you suppose, you solely must spend £599.

We’re reviewing the mid-range mannequin, referred to as the S510UQ. It has a Core i5 CPU, 8GB RAM and a 256GB SSD, and prices £799. You get devoted GTX 940 MX graphics, making it higher at taking part in video games than some. Test it out right here on Amazon.

You’ll be able to spend an additional £100 in order for you a Core i7 CPU as a substitute, though the remainder of the specs are the identical. Alternatively, the S510UA mannequin will get you a Core i7 CPU with no devoted GPU for £799. However that’s not as a lot enjoyable, is it?

The S15 comes with a one-year gather and return guarantee

Design and construct high quality

The VivoBook sequence is Asus’s mid-range household of laptops. Whereas the Asus VivoBook S15 appears to be like good, it’s not an all-metal laptop computer.

Its lid is aluminium, however the remaining is plastic. You’d have to the touch the keyboard encompass to know this, thoughts, because it’s a lifeless ringer for anodised aluminium.

Because it’s not a part of the elite ZenBook society, the Asus VivoBook S15’s lid makes use of a traditional brushed end quite than Asus’s signature round spun one too. But it surely’s nonetheless steel and nonetheless appears to be like good.

Plastic isn’t any limiter on laptop computer power, and Acer makes some finances Chromebooks that will in all probability survive being thrown in opposition to a wall, however the Asus VivoBook S15’s construct isn’t excellent.

Sure elements of the keyboard are fairly spongy, as a result of it seems to depend on a strut operating down the center, quite than having a strong sub-frame.

By the “H” key it’s strong, however press down by “D” or “;” and the keyboard flexes beneath your finger like a tupperware lid. That is what we glance to keep away from in laptop computer construct.

Different elements of the S15 design are much better, although. The display has a slender border, for instance, giving the laptop computer a reasonably petite footprint for a 15-inch mannequin.

At 1.5kg and 17.9mm thick, it is usually extremely transportable for the display dimension. Your common skinny and light-weight 13-inch laptop computer is simply 200-300g lighter.


The connections present the VivoBook is made for an ultra-mainstream viewers. There are three normal-size USBs, a full-size SD card slot and a full-size HDMI. You received’t want an adapter to plug in your present peripherals, in contrast to laptops that solely use USB-C.

We’re barely dissatisfied by the pace of the USBs, although. Just one is a USB three.zero. The opposite two are USB 2.zero ports, which is able to restrict switch speeds when you plug in an exterior exhausting drive or a really quick USB stick.

There’s additionally a one of many newer USB C sockets, for future-proofing. It’s USB three.1 Gen 1 spec port, so whereas it doesn’t have the bandwidth of the Thunderbolt three you’ll discover on some costly laptops, with 5Gbps it’s nonetheless quick sufficient for many makes use of. That features attaching a 4K monitor.

In another nations Asus places a fingerprint scanner on the VivoBook S15 S, however we don’t get one within the UK. No nice loss.

Keyboard and touchpad

The Asus VivoBook S15 S510UQ keyboard really feel is affected by the flex of its encompass, however not as badly because it might be. Its far proper facet is the spongiest half, populated by image and performance keys.

Let’s not let it off fully, although. A little bit of flex/give to the left facet additionally makes the motion much less well-defined and inflexible than it ought to be. Even a slight little bit of sponginess degrades the texture.

It is going to have an effect on gentle typists the least, and the keys are in any other case of fine high quality. There’s additionally a backlight, which is usually disregarded of mid-price laptops.

The Asus VivoBook S15 S510UQ trackpad is a typical plastic floor quite than a textured glass one. Nonetheless, it will get about as near the texture of glass as plastic can.

It’s the same dimension dimension to earlier generations of MacBook Professionals. There’s loads of room, and the pad’s click on is completely good. It’s a typical “hinge” mechanism, however doesn’t depress too far on the backside or have any lifeless zone on the prime.

Display screen

If we had been to simmer the enchantment of the Asus VivoBook S15 S510UQ right down to a single bullet level it’s a big display in a slim and light-weight body. You get a 15.6-inch show, and even the MacBook Professional 15 is considerably heavier at 1.83kg (earlier than you get too excited, it’s additionally much more highly effective).

A number of parts of the show are simply OK, nevertheless it does attain the fundamentals of what we’d be blissful to make use of day-to-day, with an IPS LCD panel and 1080p decision. It’s not super-sharp however in all fairness so, and doesn’t look odd from sure angles like a TN LCD does.

The Asus VivoBook S15 S510UQ show has a matt end, which is nice for minimising the impact of reflections, however pretty low max brightness isn’t nice for open air use. Maxing-out at 256cd/m, you’ll be capable of see paperwork because of the excessive distinction concerned, however subtler photos are going to seem too dim in brilliant daylight.

Color is not more than acceptable too. Masking simply 60.7% of sRGB, there’s clear undersaturation of bolder tones in comparison with another (usually smaller) laptops across the similar worth. With simply 42.6 p.c of Adobe RGB and 43.7 p.c of DCI P3 lined, the S15 is certainly not a laptop computer for video editors or photographers.

Nonetheless, for these like us who think about color accuracy a “good to have” quite than important, the Asus VivoBook S15 S510UQ display remains to be surprisingly satisfying. It’s all right down to distinction, the one side of the display the laptop computer nails. With a measured distinction ratio of 1117:1, it’s about pretty much as good as you’ll discover in an LCD-screen laptop computer.

It retains the VivoBook trying punchy even when the precise color isn’t super-vivid.


The Asus VivoBook S15 S510UQ makes use of Intel’s low-voltage CPUs. These have two cores quite than the 4 you’ll discover in performance-focused 15-inch laptops.

Quad-core energy is nice for many who edit video or use pro-level apps that actual tax a CPU. Nonetheless, for day-to-day use you wouldn’t discover the distinction.

Our Asus VivoBook S15 S510UQ has an Intel Core i5-7200U processor, with 8GB RAM and a 256GB SSD. It is a form of gold normal spec for slender and light-weight laptops. You would have a laptop computer with probably the most highly effective processor obtainable, but when it had an HDD as a substitute it wouldn’t really feel as slick as this VivoBook.

Simply because it doesn’t have a no holds barred construct or display, the SSD delivers pretty odd efficiency, with 524MB/s reads and 497MB/s writes. It’s simply sufficient to supply the practical day-to-day advantages of an SSD, although.

In PC Mark 10 the Asus VivoBook S15 S510UQ scores 2825 factors, just a bit greater than we noticed from the Lenovo IdeaPad 720S with the identical CPU. It scores 7010 factors in Geekbench four, once more simply fractionally higher than the Lenovo.

Evaluating these outcomes to these of a chunkier quad-core laptop computer just like the Acer VX15 is extra attention-grabbing. Its PC Mark scores should not radically greater, as a result of that is contextual take a look at based mostly on the type of duties most of us do on a weekly foundation. Geekbench four scores are a distinct story, the Acer scoring 10166 factors (with an i5 CPU). That’s nearly a 50% enhance.

Chunkier quad-core laptops do have much more CPU energy, however when you principally carry out gentle duties, you in all probability received’t make nice use of it.

The Asus VivoBook S15 S510UQ can be considered one of an rising variety of skinny laptops to have devoted graphic . It makes use of the Nvidia 940MX chipset, which we noticed not too long ago within the Lenovo IdeaPad 720S.

That is significantly better than Intel HD 620 built-in graphics, in a position to deal with some video games you would possibly play on a PS4 or Xbox One. Alien Isolation runs at a fab 64fps with graphics at low settings and backbone at 720p. It’s additionally playable with the visuals turned up and the decision set to native 1080p, averaging 27fps.

That’s not excellent however reveals you may get pretty clean outcomes with simply a few results turned off.

The tougher Deux Ex: Mankind Divided is simply price making an attempt with Low settings, at 720p. Like this it averages 28.6fps: not too dangerous. At 1080p Extremely settings, it runs at 7.2fps, reminding you this isn’t actually a gaming laptop computer. It’s a dabbler.

We have now a variety of time for low-end playing cards like this, not least as a result of they’ll match into slim laptops and don’t add an excessive amount of to the worth. Nonetheless, and never for the primary time, we want it had the newer GeForce MX150 as a substitute. It’s a successor to the 940MX and gives a roughly 20-30% enchancment in our gaming assessments.

Given the Asus VivoBook S15 S510UQ case should have extra spare room in it than comparable 13-inch fashions (and definitely feels prefer it, tapping the casing) we’re barely dissatisfied by how noticeable the fan is. It’s by no means like an plane taking off, however is louder than most ultra-slim fashions while you’re simply searching the net or writing a doc.

It appears both Asus has put much less effort into optimising fan speeds or the casing/internals aren’t pretty much as good at passive cooling as some. Asus’s web site talks about ice chilly cooling, however different laptops with low-voltage processors handle to remain pretty cool whereas operating nearly silent when, say, writing a doc.

Battery life

Asus hasn’t used the additional case area of the VivoBook S15 S to max-out the battery both. It has a 42Wh unit, smaller than the 48Wh of our previous favorite ZenBook UX310UA or Dell’s 60Wh XPS 13.

It is a little disappointing when it is a laptop computer we’d think about taking up journeys overseas. Or to the native cafe.

Taking part in a 720p video at 120cd/m² brightness, the laptop computer lasts 7 hours 15 minutes. You’ll be able to count on rather less with blended use, properly beneath most individuals’s thought of a full day’s work.

Asus says the VivoBook is made for “right now’s fast-paced city way of life”, however that clearly doesn’t keep in mind how many people work extra time.

Its audio system are honest. You don’t get the weird bass punch we heard not too long ago within the Asus ZenBook Flip S, or the larger quantity and refinement of a MacBook. Nonetheless, they don’t seem to be skinny of harsh, and we’d be blissful to take heed to a movie’s soundtrack by them after slumping right into a lodge room after an extended flight.
