Acer Swift 3 SF314-55 (i3-8145U, SSD, FHD) Laptop Review

Sascha Mölck, T. Hinum (translated by Finn D. Boerne), 01/03/2019

RAM stinginess. Acer's 14-inch notebook features an elegant and small case, a Whiskey Lake Core i3 CPU, and decent battery life. While its SSD, its matte IPS display, and its keyboard backlight are state-of-the-art in 2018, the RAM is not: Acer only includes 4 GB.

Acer’s Swift 3 SF315-55 is a complete redesign and has little to nothing in common with its predecessors bearing the same name (Swift 3 SF314-52G and Swift 3). The new model is smaller and thinner, and it is based on Intel’s Whiskey Lake platform. Its competitors are the Asus VivoBook S14 S406UA-BV023T and the Lenovo Ideapad 720S-13ARR.

Case

The SF314-55’s case is a brand-new design. It is thinner, smaller, and lighter than its predecessors’ but is still made of the exact same material: aluminum. Build quality is superb - the gaps are even and we found no overhanging lips anywhere on the device. All things considered, the Swift 3 is a fairly robust device, however we would have preferred if the base would have been a little bit sturdier than it already is. The battery is not user-replaceable, and the device lacks a maintenance opening.

In order to get to the internal hardware, the entire bottom cover must be removed. This requires removing all the screws at the bottom and prying the case open carefully with a spudger tool or a small spatula. Given that the case is fairly susceptible to scratches, you have to be very careful.

There are a total of three USB 3.1 Gen 1 ports on the unit, two USB Type-A and one USB Type-C. The latter includes support for Power Delivery and can be used as charging port. It also carries a DisplayPort signal, although this requires an extra adapter since Acer does not include any with the device. We tested both features, and both worked as expected. The Swift thus comes with two charging ports and two video-outputs.

The card reader is fairly lethargic. Copying large blocks of data results in transfer rates of no more than 29.5 MB/s. Copying 250 JPEG files of around 5 MB each topped out at 26.7 MB/s. Both tests were performed using our 64 GB Toshiba Exceria Pro SDXC UHS-II reference card. Once inserted, the SD card protruded from the case (around 15 mm, or 0.6 inches).

Wi-Fi communications are handled by Intel’s Wireless-AC 9560 modem with support for 802.11 a/b/g/n/ac. Data rates were decent under ideal conditions (no other Wi-Fi devices nearby, low distance between notebook and server).

Input Devices

The Swift 3 features a backlit chiclet-style keyboard with even and smooth keys with short key travel and a well-defined pressure point. The keyboard flexed ever so slightly while typing, but not enough to become annoying. The backlight is operated via a function key and can only be turned on or off. All things considered, the keyboard is very usable and well suited even for sustained typing sessions.

The multitouch-capable ClickPad measures 10.5 x 6.5 cm (4.13 x 2.56 inches) in size and is thus large enough for comfortable gesture input. Its smooth surface was very pleasant, and it detected input up to its very edges and corners. The integrated buttons feature short key travel and a well-defined actuation point.

Display

Subpixel array

The matte 14-inch display features a native resolution of 1920x1080 and a decent contrast ratio of 1,078:1. Unfortunately, brightness was somewhat low and maxed out at just 275.6 nits. Considering the notebook’s price we would have expected more. Nevertheless, the Swift 3’s display is still brighter than both its predecessors’. In order to be considered good enough by us, contrast ratio and brightness have to exceed 1,000:1 and 300 nits, respectively.

We noticed PWM flickering at brightness levels of 20% and below at a very high frequency of 25 kHz, which should not cause any headaches or eye strain even in sensitive users.

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 25000 Hz ≤ 20 % brightness setting

The display backlight flickers at 25000 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 20 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 25000 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9566 (minimum: 43 - maximum: 142900) Hz was measured.

Color representation was very decent out of the box already, and the DeltaE 2000 deviation for colors was just 3.86. Ideally, you want this to be less than 3. We noticed no blue tint, and sRGB color-space coverage was a very decent 98%.

The ICC profile resulting from our calibration attempts can be found for download in the box above. Before using it you need to make sure that your display is the exact same model as ours (manufacturer and model number) as it is not uncommon for a manufacturer to source its display panels from various suppliers. Applying the ICC profile to a different panel will most likely result in less accurate colors.

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↗ 18 ms rise
↘ 12 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. » 73 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (25.3 ms).
       Response Time 50% Grey to 80% Grey
41 ms ... rise ↗ and fall ↘ combined↗ 21 ms rise
↘ 20 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 49 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (40.4 ms).

The display is based on IPS technology and can thus be read from any position and angle. Display brightness was only high enough for indoor use, outdoors the device is best kept in the shade or used only on overcast days.

Performance

Acer’s Swift 3 SF314-55 is an elegant and small 14-inch notebook. It offers more than enough performance for office tasks and Internet workflows. At the time of writing, it sold for around $700 and was the series’ entry-level SKU. Better-equipped SKUs are also available.

Processor

The Swift 3 is powered by an Intel Core i3-8145U dual-core CPU. The ULV model with a TDP of 15 W is based on Intel’s Whiskey Lake architecture and was fast enough for the most common range of applications. Its base clock speed of 2.1 GHz can turbo boost up to 3.7 on two cores and 3.9 GHz on one. It also supports Hyper-Threading, meaning it can run two threads per core simultaneously.

During our Cinebench multithread test the CPU ran at 3.7 GHz for a few seconds and subsequently reduced its clock speed to 3.4-3.5 GHz. In the single-thread test it clocked between 3.7 and 3.9 GHz. At least on mains, that is. On battery, CPU clock speeds were reduced to just 1.9-2.1 GHz and only occasionally clocked higher than that for very short periods of time. Consequently, the Cinebench R15 scores on battery were just 60 (single-thread) and 156 (multithread).

We found no way in our review unit’s BIOS setup to change this behavior and enable turbo boost on battery. After we had finished our tests, Acer released a new BIOS update, version 1.05, but that also did not have any impact at all.

We verify whether or not turbo boost is applied over long periods of time by running Cinebench R15’s multithread test in a loop for at least 30 minutes. Our review unit’s score dropped between the first and second run of the test but remained steady and consistent afterwards. Therefore, performance does not decrease over time, and turbo boost is applied throughout the entire test at around 3.4-3.5 GHz.

We ran the same test on battery as well, and the device scored a very consistent 152 points over and over again.

There are no architectural differences between Whiskey Lake and Kaby Lake. In other words: The per-MHz-performance is identical between the two. However, Whiskey Lake’s optimized manufacturing process allows for higher clock speeds. Accordingly, the 8145U is only faster in our tests thanks to its higher turbo boost speeds compared to its Core i3-8130U Kaby Lake predecessor.

System Performance

Thanks to the combination of a Core i3 CPU and an NVMe SSD the system was very smooth and responsive at all times, and we have not encountered any issues. The Swift 3 was more than powerful enough for the most common office and Internet applications, which is further corroborated by its good PCMark benchmark scores. However, Acer could have improved performance somewhat by making use of the memory controller’s dual-channel mode, but the RAM soldered onto the motherboard only runs in single-channel mode. Activating dual-channel mode retroactively is not possible.

Storage Devices

The 128 GB M.2-2280 NVMe SSD is made by Kingston, and around 92 GB of the storage space is user-accessible out of the box. The rest is taken up by the Windows installation and the recovery partition. Traditionally, NVMe SSDs tend to be much faster than SATA III SSDs due to the fact that they are connected to the much faster PCIe 3.0 x4 bus instead of the SATA interface. While this particular Kingston SSD performed quite well, it was certainly not the fastest SSD available.

Gaming Performance

The Swift 3’s combination of CPU and GPU is capable of running some games smoothly. However, these are limited to games with very modest hardware requirements and will only run smoothly with reduced resolutions and details. More-demanding games, like Battlefield V, are not going to be playable at all.

Emissions & Energy

System Noise

Acer’s 14-inch notebook remained quiet regardless of load. When idle, the fan was usually off and the device was thus completely silent. Under load the fan only revved up slightly, and the maximum sound pressure level determined during our stress test was a low 31.4 dB(A).

Temperature

Swift 3 stress test
Swift 3 stress test

Our stress test (Prime95 and FurMark running simultaneously for at least one full hour) was performed differently on mains and on battery. The CPU ran at between 2.2 and 2.5 GHz on mains and between 1.8 and 2.1 GHz on battery. The GPU ran at its full speed regardless of power source.

The Swift 3 remained fairly cool overall. We found two hot spots of more than 40 °C while running our stress test, but the device was much cooler during everyday use. Keep in mind that our stress test is an extreme load scenario that is rarely ever encountered in the real world. We use this test to determine any bottlenecks and potential stability issues.

Power Consumption

Acer’s SF314-55 was comparatively economic and efficient. Maximum power consumption when idle was just 6.1 W, which increased to 35.3 W while running our stress test (Prime95 and FurMark simultaneously for at least one full hour). With just Prime95 running, power consumption was even higher and peaked at 38.4 W. The power supply is rated at 45 W.

Verdict

Acer’s Swift 3 SF314-55 is a 14-inch notebook with an elegant and compact metal case. It offers plenty of performance for everyday office and Internet tasks thanks to its Core i3 CPU, which manages to outperform its Kaby Lake competitors like the Core i5-7200U due to its higher turbo boost speeds. Despite this, the device remained very quiet and cool in all load scenarios.

An NVMe SSD makes for a buttery smooth and responsive system, and the SSD can be upgraded. Unfortunately, this requires removing the bottom cover and opening the case. The IPS panel offers great viewing angles and a good contrast ratio but its maximum brightness is nothing to write home about. Considering the laptop’s price we would have expected a brighter display. It is only bright enough for indoor use. The backlit keyboard left a good impression and was certainly well usable. Battery life was pretty decent; however, it comes at a price: CPU turbo boost is practically not applied on battery at all.

Our biggest criticism is the device’s meager RAM configuration. 4 GB is not enough considering the notebook’s price of around $700.

In addition, the RAM is soldered onto the motherboard and there are no free RAM slots available, which means it is impossible to add more memory. This is most certainly going to be a deal-breaker for many potential customers. For $100 more you can get the SF314-55-34T6 SKU with not only 8 GB of RAM but also a more spacious 256 GB SSD.
