Acer Swift 5 (SF515-51T) review – the world’s lightest 15-inch laptop yet

Acer Swift 5 (SF515-51T) review – the world’s lightest 15-inch laptop yet

Say hiya to the lightest 15-inch laptop on the planet as much as this date. Acer has created the unimaginable – they went beneath a kilogram with a pocket book of this measurement. Regardless of missing the large advertising of LG and their Gram line-up, Acer Swift 5 (SF515-51T) is a star of its personal constellation. Along with that, Acer managed to suit a touchscreen panel to this pocket book.

Clearly, all of this comes at a worth. Fairly actually – it begins at $1100 for a Core i5-8265, eight GB of RAM and 512 GB SSD. Properly, sure, it’s a fairly excessive price ticket however the undeniable fact that the market is way from saturated with merchandise of this type simply justifies that. An entire different matter is how helpful a laptop of this weight and measurement is however let’s depart this extremely subjective matter to you – the shoppers.

You possibly can verify the costs and configurations in our Specs System:

What’s in the field?

The very first thing greeting you, once you open the field is the Swift 5 (SF515-51T) itself wrapped in a mild white material. Beneath it, there’s principally nothing (some manuals solely). On the proper aspect of the field is situated a separate compartment for the 45W energy brick.

Design and development

Most undoubtedly this can be a refined design. Nevertheless, the 16 mm profile and 990 grams weight gave a blow to one thing fairly necessary for a cellular system – the rigidity. So Acer needed to unfold their ideas and funds on two fronts – choosing the lightest supplies, but in addition the most sturdy ones. This result in a pleasant mix of magnesium and aluminum which after the paint job feels lots like plastic… however it isn’t.

If we take a look at the lid for instance – it’s tremendous skinny and has a Full HD panel with contact help. However with a view to minimize the weight, they needed to ditch the standard glass cowl we see on a touchscreen laptop. This makes the lid much less sturdy and tremendous flexible.

Frankly, this transfers to the physique of the pocket book which can also be prone to bends. Though you must put much more strain on it to take action, it’s nonetheless far much less sturdy than an Acer Swift three for example.

Let’s transfer on to the subsequent step – the keyboard. The format is properly spaced, apart from the “Up” and “Down” arrow keys. Sadly, there are not any NumPad keys right here. That is inevitable, nevertheless, due to the thinness of the pocket book, it should impede the I/O. On the vibrant aspect – the keys really feel tactile and the journey is arguably the longest in a 16 mm laptop. Along with that, there’s a backlight to light up the golden-marked keys.

Nonetheless, on the enter units, there’s the touchpad which feels fairly satisfactory and clicky. We want to embrace the touchscreen on this class as nicely. Regardless of how a lot we like touchscreens on laptops, we should always admit that there isn’t any place for such on the Swift 5. We couldn’t consider some other place by which one would use the touchscreen besides full flat. It’s simply too wobbly however come on – it’s to be anticipated, in any case this can be a tremendous compact and light-weight machine.


Regardless of the type issue, Acer has provided the Swift 5 (SF515-51T) with two USB Sort-A ports (acquired one thing to say, Apple?!). Each of them are three.1 (Gen. 1), and the closest to the consumer can cost different units. The remainder of the I/O includes of a charging plug, HDMI port, a USB Sort-C three.1 (Gen. 2) and a headphone/mic jack. Furthermore, the majority of them are situated on the left aspect, whereas the three.5 mm jack is lonely on the proper aspect.

Disassembly, improve choices, and upkeep

Now let’s examine what Acer has put inside the lightest laptop in the world. Truly, is there something inside? First issues first, although, let’s unscrew the 12 torx screws holding the backside plate in place. Then we’re simply going to unpry it from the principal physique and ah! Thank God… there’s truly one thing inside.

Not a lot, although. As you’ll be able to see the cooling is comprised of a single heatpipe, which delivers the warmth from the CPU straight to the tiny little heatsink.

To the proper of the cooling fan is the place you’ll find the small overcrowded motherboard. Simply beneath the CPU are the soldered RAM chips, whereas its proper aspect is occupied by a 512GB NVMe SSD – once more soldered to the most important board.

This partially explains the tremendous low weight of the Acer Swift 5 (SF515-51T). Nevertheless, there’s nonetheless an M.2 slot for enlargement there.

Most of the backside free area is taken by the battery pack. We’re completely satisfied that Acer was capable of match a 53.9 Wh unit inside this tremendous skinny chassis however we nonetheless assume there’s more room that would have been utilized by a fancy-shaped battery.

Show high quality

Acer Swift 5 (SF515-51T) is provided with a Full HD touch-enabled IPS panel, mannequin quantity LG LP156WFa-SPG2 (LGD05F7). Its diagonal is 15.6″ (39.62 cm), and the decision 1920 х 1080 pixels. The display ratio is 16:9, and we’re taking a look at a pixel density of – 142 ppi, and a pitch of zero.18 х zero.18 mm. The display turns into Retina when seen at a distance equal to or larger than 60cm (24″) (from this distance one’s eye stops differentiating the separate pixels, and it’s regular for taking a look at a laptop).

It has wonderful viewing angles. We provide photographs at 45° to guage picture high quality.

The measured most brightness of 355 nits in the center of the display and 337 nits as a mean for the entire space, with a most deviation of 13%. The Correlated Shade Temperature on a white display is 6700Okay – a bit colder the optimum for the sRGB commonplace of 6500Okay. The typical colour temperature via the gray scale earlier than profiling primarily matches the optimum at 6450Okay.
In the illustration under you possibly can see how the show performs from a uniformity perspective. In different phrases, the leakage of sunshine from the mild supply.

Values of dE2000 over shouldn’t happen, and this parameter is one in every of the first you need to examine in case you intend to make use of the laptop for colour delicate work. The distinction ratio is ok – 1140:1 (1130:1 after profiling).

To ensure we’re on the similar web page, we want to offer you a bit of introduction to the sRGB shade gamut and the Adobe RGB. To start out, there’s the CIE 1976 Uniform Chromaticity Diagram that represents the seen specter of colours by the human eye, supplying you with a greater notion of the colour gamut protection and the shade accuracy.

Inside the black triangle, you will notice the commonplace colour gamut (sRGB) that’s being utilized by tens of millions of individuals in HDTV and on the net. As for the Adobe RGB, that is utilized in skilled cameras, screens and so on for printing. Principally, colours inside the black triangle are utilized by everybody and that is the important a part of the shade high quality and shade accuracy of a mainstream pocket book.

Nonetheless, we’ve included different shade areas like the well-known DCI-P3 normal utilized by film studios, in addition to the digital UHD Rec.2020 normal. Rec.2020, nevertheless, continues to be a factor of the future and it’s troublesome for in the present day’s shows to cowl that properly. We’ve additionally included the so-called Michael Pointer gamut, or Pointer’s gamut, which represents the colours that naturally happen round us each day.

The yellow dotted line exhibits Acer Swift 5 (SF515-51T)’s shade gamut protection.

Its show covers 97% of the sRGB/ITU-R BT.709 (net/HDTV normal) in CIE1976.

Our “Design and Gaming” profile delivers optimum colour temperature (6500Okay) at 140 cd/m2 luminance and sRGB gamma mode.

We examined the accuracy of the show with 24 generally used colours like mild and darkish human pores and skin, blue sky, inexperienced grass, orange and so forth. You possibly can take a look at the outcomes at manufacturing unit situation and in addition, with the “Design and Gaming” profile.

Under you’ll be able to examine the scores of Swift 5 (SF515-51T) with the default settings (left), and with the “Gaming and Web design” profile (proper).

Response time (Gaming capabilities)

We check the response time of the pixels with the ordinary “black-to-white” and “white-to-black” technique from 10% to 90% and vice versa.

We recorded Fall Time + Rise Time = 31 ms.

PWM (Display flickering)

Pulse-width modulation (PWM) is a simple approach to management monitor brightness. Once you decrease the brightness, the mild depth of the backlight isn’t lowered, however as an alternative turned on and off by the electronics with a frequency indistinguishable to the human eye. In these mild impulses, the mild/no-light time ratio varies, whereas brightness stays unchanged, which is dangerous to your eyes. You possibly can learn extra about that in our devoted article on PWM.

Acer Swift 5 (SF515-51T) is provided with a flicker-free panel. This implies it doesn’t use PWM to regulate its display brightness at any degree, making it protected to be used in prolonged durations of time on this facet.

Blue mild emissions

Putting in our Well being-Guard profile not solely eliminates PWM but in addition reduces the dangerous Blue Mild emissions whereas retaining the colours of the display perceptually correct. Should you’re not acquainted with the Blue mild, the TL;DR model is – mild emissions that negatively have an effect on your eyes, pores and skin and your entire physique. Yow will discover extra details about that in our devoted article on Blue Mild.


The touchscreen Full HD IPS panel on this pocket book is certainly one of the higher ones on the market.

As we anticipated, the outcomes from this check are usually not in favor of Acer Swift 5 (SF515-51T). It barely reached 2 GHz all through the whole check, whereas the frequency at the finish was 1.68 GHz. For sure, it’s method off the competitors. Let’s be trustworthy, although, you possibly can’t actually anticipate excessive clock speeds from this lad. In any case, it has roughly the similar quantity as a Zippo lighter.

Gaming consolation

All in all, Swift 5 (SF515-51T) does an excellent job in disipating the warmth out of its tiny physique. Along with that, it’s fairly silent and the hottest spot is round 48C, which isn’t dangerous given the circumstances.


Lengthy reside the light-weight champion! If you’d like a modern laptop that hardly wakes the scale up, that is the one for you. When you want to put your pocket book in your backpack and never discover it – you guessed it – that is the one for you. Nevertheless, needless to say you’re most likely going to interrupt it (or no less than bend it) for those who put anything in that backpack.

However, Acer has made every part to maintain their ultrabook on level. You’ve gotten the choice of a Core i7-8565U. Sadly, the Swift 5 (SF515-51T) won’t ever have the ability to cool it down adequately, so you’re caught with round 20% decrease efficiency than the Inspiron 15 7580 for instance. Nevertheless, the Swift 5 (SF515-51T) didn’t stutter for a second and offered us with a really swift working expertise.

Furthermore, its battery life is gigantic – 11 hours of searching the net and 9 hours of video playback. Good utilization of a 53.9 Wh battery, Acer. That is one among the robust factors of this pocket book.

One other one is the display – in all probability certainly one of the greatest panels that would have been placed on this system (LG LP156WFA-SPG2). It has all the perks of an IPS panel, plus a large shade protection and correct shade illustration. The truth is, with the assist of our Gaming and Net design profile, it achieves a mean dE of simply 1.1 which is web-designer-friendly. Lastly, and doubtless most significantly, it doesn’t use the dangerous PWM to regulate its brightness.
