Acer Spin 1 (N3450, FHD) Convertible Review

Sascha Mölck, Tanja Hinum (translated by Mark Riege), 07/09/2017

Untiring.Acer's 11.6-inch convertible pleases with a very long battery life and an IPS display with stable viewing angles.

For the original German review, see here.

After the Spin 5 and the Spin 7, we are now testing the Spin 1, the smallest and one of the weakest models of Acer's convertible series. The 11.6-inch model is driven by a Celeron quad-core processor of the Apollo Lake generation. Competitors of the convertible include devices such as the Asus VivoBook Flip 12 TP203NAH, the HP Pavilion 11 x360, the Medion Akoya E2215T, and the Dell Latitude 3189.

Case and Features

Acer has packed the technology of the Spin 1 into a two-tone plastic case. The back of the lid and bottom of the case are colored in a turquoise/light blue tone. Both elements also have a linen texture. The display frame and the top of the base unit are black. The top of the base also has a texture simulating brushed metal. The case is well-built and does not show any faults in that respect. However, the base unit could have been slightly stiffer. The battery is built-in, and the computer does not have a maintenance flap.

There are no surprises in terms of the connections. The convertible offers three Type-A USB ports (1x USB 3.1 Gen 1, 2x USB 2.0) and there is a video port (HDMI). Acer places the ports on both sides towards the back, which leaves the space next to the palm rests free from cables.

The WLAN module of the Spin 1 has a Qualcomm (QCA9377) chip, which, as well as the 802.11a/b/g/h/n WLAN standards, also supports the fast ac standard. The transfer speeds we measured under optimal conditions (no other WLAN devices in close proximity, close distance between notebook and server PC) were good.

Input Devices

Acer has provided the Spin 1 with a chicklet keyboard without backlight. The flat, slightly roughed keys have a short stroke and a pronounced pressure point that knows how to please. While typing, the keyboard yields slightly - more in the right half than in the left. This was not problematic. Overall, Acer delivers a very decent keyboard here, which is also made for frequent writing work.

The multitouch-capable ClickPad occupies an area of about 10.5 x 6 cm (~4.1 x 2.4 in). This offers plenty of space for gesture controls. The smooth surface of the pad does not prevent the fingers from sliding. The pad also reacts to input at the corners. It has a short stroke and a clear pressure point.

The touchscreen of the convertible supports 10 touch points. It reacts to inputs promptly, and can be operated with the fingers as well as an active pen, which would have to be purchased separately.

The 11.6-inch touchscreen display of the Spin 1 has a native resolution of 1920x1080 pixels and offers a good contrast (1195:1). The maximum brightness of the display (246.9 cd/m2) could have been higher, since we can assume that the device is used in various locations under various light conditions. Positive: at no time does the screen show any PWM flickering.

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 not detected

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9394 (minimum: 43 - maximum: 142900) Hz was measured.

In the delivery state, the display shows a decent color presentation. At 4.27, the DeltaE-2000 color deviations are not too far from the target range (DeltaE smaller than 3). The screen does not suffer from a blue 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
24 ms ... rise ↗ and fall ↘ combined↗ 14 ms rise
↘ 10 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 34 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (25 ms).
       Response Time 50% Grey to 80% Grey
36 ms ... rise ↗ and fall ↘ combined↗ 19 ms rise
↘ 17 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. » 29 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (39.8 ms).

Acer provides the Convertible with an IPS panel that has stable viewing angles. Thus the screen can be read from any position. In most cases, the low display brightness and the reflective screen surface prevent outdoor use. At most, the device can be used in shady surroundings or when the sky is overcast.

Performance

Acer's 11.6-inch convertible offers sufficient performance for applications in the office and Internet areas. Our test device can be purchased for about 425 Euros (~$480; in the US a similar model with the Celeron N3350, 4GB DDR3L, and 32GB Storage is currently available for $300). Other feature variants are available with prices starting at 300 Euros (~$340).

Processor

The Spin 1 has Intel's Celeron N3450 (Apollo Lake) quad-core processor on board. The CPU is one of the energy efficient models. A TDP of only 6 watts allows passive cooling of the chip, which is also done here. The processor operates at a basic speed of 1.1 GHz, which can be increased via turbo up to 2.2 GHz. The turbo is used in both mains and battery operations. However, in the Multithread tests of the Cinebench benchmarks, it is only used sparingly. It runs though these benchmarks with 1.5 to 1.6 GHz.

This speed range can also be maintained over prolonged periods of time. We test this by running the Multithread test of Cinebench R15 for about 30 minutes in a constant loop. The results remain consistently at the same level, and there is no drop in performance.

System Performance

The system runs smoothly and we did not encounter any problems. The built-in processor offers sufficient computing power for applications in the office and Internet areas. The result in the PC Mark 8 benchmark corresponds to the performance capabilities of the SoC. By switching the HDD for an SSD, the overall performance could be increased. This would make the system react quicker and the loading times would decrease. It is not possible to increase the performance by activating the dual-channel mode, since the notebook has only one memory storage slot.

Graphics Card

The Graphics output is provided by Intel's HD Graphics 500 graphics core. The GPU supports DirectX 12 and operates at speeds of up to 700 MHz. The results in the 3D Mark benchmarks remain below our expectations. The graphics core should clearly be ahead of its predecessors (HD Graphics 400/405), since it has a more powerful architecture. Apparently the GPU cannot run at full power.

Gaming Performance

The weak hardware of the computer can bring only a few games to the screen smoothly - at low resolutions and low quality settings. Of course that includes only games that make very low demands on the hardware. You can find more playable games in the Casual Games section of the Windows Store.

Emissions and Power

Noise Emissions

The Spin 1 does not have a fan. You can only hear the discrete whir of the hard drive. But this can only really be heard in silent surroundings. By exchanging the HDD for an SSD, you would get a completely silent system.

Temperature

The Spin 1 in the stress test
The Spin 1 in the stress test

The spin runs through our stress test (Prime95 and FurMark run for at least one hour) in the same way in mains and battery operation. Since the device is cooled passively, the operating speeds drop rather quickly. The CPU begins the test at 1.2 GHz. From then on, the clock speed drops continuously. After about 40 minutes, the speed is at 400 to 500 MHz and remains at that level. The graphics core begins the test at 200 MHz and is then throttled down to 150 to 100 MHz. The heat development of the computer remains within limits.

Verdict

The Acer Spin1 SP111-31-C79E, provided by notebooksbilliger.de
The Acer Spin1 SP111-31-C79E, provided by notebooksbilliger.de

The Apollo Lake quad-core processor built into the Spin 1 offers sufficient computing power for applications in the office and Internet areas. The decoder integrated into the GPU enables playing all the usual video formats.

There is no lack of storage, since Acer provides a 500 GB hard drive. To exchange the HDD for an SSD, the case has to be opened. There is no maintenance flap.

The Spin 1 turns out to be an untiring writing and surfing machine.

The small computer can shine in terms of the battery life. In our practically relevant WLAN test, the convertible achieves a runtime of almost 9.5 hours. The built-in keyboard left a very decent impression and is also suitable for more frequent writing tasks. The Full HD IPS display pleases with stable viewing angles, a good contrast, and a very decent color reproduction. The brightness, however, could have been higher.
