Acer Swift 1 SF114-31-P6F6 Notebook Review

Sascha Mölck, Stefanie Voigt (translated by Liala Stieglitz), 02/14/2017

Enduring mobility. Acer's 14-inch laptop pleases with its silent system and very long battery life. This is due to the combination of a Braswell processor and high-capacity battery. With a price of 400 Euros (~$422), it is also an affordable device.

The Swift 1 is the entry-level model in Acer's Swift lineup. Core i and Core m processors are absent here. Acer relies on Braswell CPUs. The company kills two birds with one stone with this device: Firstly, the Swift is an affordable, enduring laptop in the series, and secondly, it is a rival for the Chromebook without the restrictions involved. A permanent Internet connection is not needed and there are no desktop applications. Laptops, such as Medion's Akoya S4219Lenovo's E31-70HP's Stream 13 and HP's Chromebook 14 are among its rivals.

Case and Connectivity

The casing of the Swift 1 is made mainly of plastic. Only the base unit's upper side is made of aluminum. Despite the use of plastic, the device can be described as stylish. As to its build, the laptop does not show any major shortcomings. This is slightly different as far as the robustness is concerned. In our opinion, the base unit can be warped a bit too easily. This is true to an even greater extent of the lid.

Acer has equipped the Swift 1 with the most necessary interfaces. One of the two Type-A USB ports supports the USB 3.0 standard. Acer should have installed a further Type-C port. The interface distribution is good: They are in the rear on both sides. The installed Wi-Fi module is a Wi-Fi chip (QCA9377) from Qualcomm. It supports the 802.11a/b/g/n Wi-Fi standards as well as the faster ac standard. However, the transmission rates are very poor, even under ideal conditions (no other Wi-Fi devices in the vicinity, short distance between the laptop and the server PC).

The installed memory card reader is not the fastest of its kind. A maximum transfer rate of 34.5 MB/s is achieved when copying large data blocks. Transferring 250 JPG image files (approx. 5 MB each) is performed at 20.6 MB/s. We test the memory card reader with a Toshiba Exceria Pro SDXC 64 GB UHS-II reference card. Unfortunately, SD cards cannot be inserted completely into the reader; they protrude by about 5 mm (~0.2 in).

Input Devices

The Swift 1 comes with an unlit chiclet keyboard. The flat, lightly roughened keys have a short drop and clear pressure point. The keyboard yields slightly when typing on it. However, we did not find this annoying. Overall, Acer has installed a very decent keyboard that is designed for even prolonged typing sessions. The multitouch ClickPad has a surface area of approximately 10.6 x 6.1 cm (~4.2 x 2.4 in). Thus, it provides enough room for using gestures. The pad's sleek surface makes it easy for the fingers to glide over it. The pad has a short drop and defined pressure point.

Display

Pixel grid

The matte 14-inch screen in the Swift has a native resolution of 1366x768 pixels. Neither its brightness (247.2 cd/m²) nor its contrast (474:1) convinces. However, the rates are acceptable in view of the laptop's price. Unfortunately, the screen exhibits PWM flickering at a frequency of 200 Hz in brightness levels of 90% and lower. This can lead to headaches and/or eye problems in sensitive users. To make things worse, the screen flickers permanently without the power supply, i.e. even at a brightness of 100%. The second screenshot under PWM (pulse-width modulation) illustrates this.

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM detected 200 Hz ≤ 90 % brightness setting

The display backlight flickers at 200 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 90 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 200 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below.

In comparison: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8781 (minimum: 43 - maximum: 142900) Hz was measured.

The panel surprises with a relatively good color reproduction in the state of delivery. With a DeltaE 2000 shift of 3.01, it just misses the target range (DeltaE less than 3). However, the screen exhibits a bluish tint.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
30 ms ... rise ↗ and fall ↘ combined↗ 16 ms rise
↘ 14 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 74 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (25.6 ms).
       Response Time 50% Grey to 80% Grey

The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 18 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (41 ms).

Acer has installed a viewing angle dependent TN panel. Thus, the screen is not legible from every position. The Swift 1 can be used outdoors when the sun is not shining. The laptop's screen has been designed for indoor use.

Performance

With its Swift 1, Acer has a 14-inch laptop that is suitable for using basic office and Internet applications. The integrated video decoder also allows playing videos - at home or on the go. Our review sample is priced at approximately 400 Euros (~$422). Only one other model (Celeron N3060, 64 GB eMMC) was available for 300 Euros (~$317) at the time of testing.

Processor

The Swift is powered by Intel's Pentium N3710 (Braswell) quad-core processor. The CPU's computing power is enough for simple office and Internet applications. The SoC's low TDP allows passive cooling, which is also implemented here. The CPU clocks at a base speed of 1.6 GHz, which can be boosted to 2.56 GHz via Turbo. Our CPU tests were performed at full speed. It is too bad that Acer relies on the Braswell platform and not on the new Apollo Lake platform. The CPU and GPU performance of the latter has been increased considerably compared with Braswell.

System Performance

The system makes a smoother impression during use than we are used to from other comparable devices. Acer seems to have matched the components well. The very decent PCMark 8 scores confirm this impression. It is not possible to increase the total performance. Positive: The soldered working memory operates in dual-channel mode.

Storage Device

Data can be stored on an eMMC module with a total capacity of 128 GB. Almost 96 GB of this can be used. The storage device's transfer rates are on a normal level for eMMC modules. The storage capacity can be expanded via an SD card when required. However, this is rather a theoretical option. Since SD cards protrude out of the memory card reader by about 5 mm (~0.2 in) and the cards are not locked in place, this is not really practical.

Graphics Card

Intel's HD Graphics 405 GPU is installed. It supports DirectX 12 and clocks at speeds of up to 700 MHz. The 3DMark scores are on a normal level for the GPU installed here. The dual-channel working memory has a positive impact here. A look at our comparison chart reveals that the HD Graphics 505 successor is considerably stronger - on a low level.

Gaming Performance

The installed SoC can render only a few games smoothly. The older a game is, the more likely it is that it will run on the Swift. However, the user will have to be satisfied with low resolutions and low quality settings. Considerably more playable games are found in Casual Games in Windows Store.

Emissions and Energy Management

System Noise

The Swift is cooled passively. Thus, a fan that could produce noise is not installed. An occasional crackling from inside the laptop was audible during our gaming test. However, the laptop's speakers have to be turned off and the user has to be in a very quiet environment to hear this at all. This was not observed in routine office use.

Temperature

The Swift in the stress test
The Swift in the stress test

The Swift performed our stress test (Prime95 and FurMark run for at least one hour) similarly in AC and battery mode. The CPU and GPU clocked at high speeds for only a few seconds before the processor was throttled to 800 MHz and the graphics core to 480 MHz. These rates were maintained for 20 to 30 minutes. Then, the CPU and GPU gradually throttled a bit further to 720 MHz (CPU) and 460 MHz (GPU). The laptop's temperature development is within limits. 40 degrees Celsius (~104 degrees Fahrenheit) was exceeded on two measuring points during the stress test. The temperatures were much lower in routine use.

Battery Runtime

A sticker on the Swift promises a battery life of up to 13 hours. This time proved to be quite realistic in practice. Acer's laptop achieved a runtime of 11:01 hours in our practical Wi-Fi test - a very good outcome. Here, we simulate the load needed for opening websites. The "Balanced" profile is enabled, the energy-savings mode is disabled, and the screen's brightness is set to approximately 150 cd/m².

In review: Acer Swift 1 SF114-31-P6F6. Test model provided by Notebooksbilliger.de

The Swift 1 is the lowest-performance and cheapest model in Acer's Swift lineup. However, it does not need to hide. Although the casing is mainly made of plastic, the Swift 1 can be described as stylish. This is also due to its slim exterior. The Swift 1 cannot compete with the Core i and Core m processors in its more expensive siblings. The installed Pentium N3710 processor is suitable for basic office and Internet applications.

Acer has a stylish, slim and enduring typewriter and browsing machine in its portfolio. The price of just under 400 Euros (~$422) also makes the device affordable for pupils and students.

The laptop is always silent and does not heat up excessively. The storage device has a capacity of 128 GB. Almost 96 GB of this can be used. This should be enough for most users. The laptop does not feature a backlit keyboard. The installed unit makes a very decent impression and can be used for frequent typing. The superb battery life adds to that. The laptop's relatively low price is reflected in the screen. Acer has installed a dark, low-contrast, viewing angle dependent panel. Nevertheless: The screen is acceptable in view of the low price.

Finally, a wish list for a potential successor: Dear Acer, in addition to an Apollo Lake SoC, a backlit keyboard, and at least one Type-C USB port would be appreciated. An IPS screen would round things off, but this will probably remain a wish considering the Swift 1's price.
