Asus Vivobook F556UQ-XO626D Notebook Review

Sascha Mölck (translated by Martina Osztovits), 02/26/2017

Stylish. With the Vivobook, Asus offers a 15.6-inch all-round device which immediately catches the eyes: The company uses a throughout white chassis. The feature set is alright, too: Core i5 processor, GeForce graphic card, ac Wi-Fi, Type-C USB. The bundle costs less than 500 Euros (~$528).

For the original German review, see here.

The Asus Vivobook F556UQ-XO626D is the identically designed sibling of the Vivobook X556UQ-XO076T, which we already reviewed in summer 2016. The current test model differs from its sibling in two aspects: With the Core i5-6198DU, it features a Skylake processor, which is not too often found in notebooks. The second difference is the look: Asus uses a snow-white chassis with white keys. The competitors include devices such as the HP 15-ba077ng, the Acer Aspire E15 E5-553G, and the Lenovo IdeaPad 310-15ISK.

Since the F556UQ and the X556UQ share the same design, we will not cover case, connectivity, input devices, display, and speakers in detail here. Information about these is available in our X556UQ review.

Display

Pixel grid
Pixel grid

The Vivobook features a matte 15.6-inch display with a native resolution of 1366x768 pixels. It is the same dark, low-contrast, viewing-angle unstable model which we are familiar with from the already reviewed sibling. Nevertheless, the measurement results are slightly different, since two identical panels are never exactly the same.

We could not detect PWM for reducing the brightness, but a permanent flickering caused by the power adapter (in mains operation, not on battery). See the screenshot besides PWM. However, this flickering is only measurable; it is neither notable nor disturbing.

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: 54 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8499 (minimum: 43 - maximum: 142900) Hz was measured.

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
23 ms ... rise ↗ and fall ↘ combined↗ 7 ms rise
↘ 16 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. » 23 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (26.6 ms).
       Response Time 50% Grey to 80% Grey
47 ms ... rise ↗ and fall ↘ combined↗ 25 ms rise
↘ 22 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. » 74 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (42.4 ms).

Performance

With the Vivobook F556UQ, Asus has a 15.6-inch all-round device in its line-up. It brings sufficient performance for everyday tasks and is able to run games. Our test model costs about 460 Euros (~$485) and is currently the cheapest variant of this series. Other configurations and color variants are available. Models of the identically designed X556UQ series increase the choice of products.

Processor

The Vivobook is powered by a Core i5-6198DU (Skylake) dual-core processor. This is basically a Core i5-6200U processor with a weaker iGPU (HD Graphics 510 instead of HD Graphics 520) than usual. The used CPU is a mid-range ULV model, which should suffice for most users' requirements. The Core i5 processor works at a base clock of 2.3 GHz. Thanks to Turbo, the clock rate can increase to 2.7 GHz (both cores) and 2.8 GHz (single core). The Turbo is actually used in mains operation and on battery.

System Performance

We did not face problems. The system works smoothly. The good results in the PCMark benchmarks confirm our subjective impression. The all-round device delivers sufficient performance for office and Internet applications. The computer can even run games. It is possible to further improve the system performance by replacing the HDD with an SSD. This would make the system more responsive and loading/opening of programs/files would take less time.

Graphics Card

The Vivobook comes with a dedicated GeForce 940MX graphics card from Nvidia. This model is a mid-range GPU. It supports DirectX 12 and clocks at up to 1176 MHz. The GPU is supported by 2048 MB DDR3 VRAM. The results of the 3DMark benchmarks are normal. Apart from the used GeForce 940MX variant, there are two other models. The latter feature GDDR5 VRAM. Further information about this is available in our Acer TravelMate P259-MG review.

Gaming Performance

The CPU-GPU combination of the Vivobook can run many games smoothly in HD resolution (1366x768 pixels) with low to medium quality settings. Higher settings are possible in games without high hardware requirements. An example is FIFA 17. However, many demanding games require decreasing the resolution and/or quality settings in order to achieve playable frame rates. Very demanding games such as Deus Ex Mankind Divided and Mafia 3 are unplayable.

Emissions and Energy

System Noise

In idle mode, the fan permanently runs at low speed, but it is not audible since the hard drive is louder. Even if the hard drive stands still, the fan can just be heard in very quiet environments if at all. The system will run significantly quieter in everyday use if you replace the HDD with an SSD. The fan certainly gets louder under load. We measured a noise level of 42.6 dB during the stress test.

An electronic noise can occasionally be heard. We observed this noise during copying gaming benchmarks to the hard drive. However, the noise is only audible in very quiet environments.

Temperature

The Vivobook during the stress test
The Vivobook during the stress test

Our Vivobook behaves slightly different in our stress test (Prime95 and Furmark run for at least one hour) in mains operation and on battery. The graphics core always clocks at full speed (1,176 MHz). In mains operation, the processor works at 2.2 to 2.3 GHz. The clock rate occasionally falls to 400 MHz. On battery, the CPU permanently clocks at 400 MHz. The notebook hardly gets warmer during the stress test (in mains operation). The temperatures remain below 40 °C in all measurement segments.

Power Consumption

There are no abnormalities in the realm of energy demand. The power consumption is normal for the used hardware platform regardless of the load. The 65-Watt power adapter does not reach its limits.

Battery Life

Our real-world Wi-Fi test simulates the load during web surfing. The profile "Balanced" is active, the power-saving options are disabled and the display brightness is set to about 150 cd/m². The Vivobook achieves a battery life of 5:38 h, which surprisingly is 70 minutes shorter than its sibling's.

In review: The Asus Vivobook F556UQ-XO626D. Test model provided by Notebooksbilliger.de

The Asus Vivobook F556UQ is a 15.6-inch all-round laptop. It is not too expensive at a price of about 460 Euros (~$485). The used Core i5 processor is suitable for all usual fields of application. Together with the GeForce graphics card, it can run many current games smoothly. The computer hardly gets warmer regardless of the load and, at least during everyday use, it works quietly. Thanks to a 500 GB hard drive you will not run out of storage space quickly. It is possible to replace the hard drive with a higher-capacity model or an SSD. However, this requires opening the laptop. The existing maintenance hatch only allows access to the RAM slot.

With the Vivobook F556UQ, Asus delivers a balanced all-round device. You get high performance for a relatively low price.

The keyboard appeared to be decent and is sufficient for home use. Moreover, the battery runtimes are good. Usually, the display is a big weakness in budget notebooks. This is also true for the Vivobook. Asus incorporated a quite dark, low-contrast, viewing-angle unstable model. However, the display quality is acceptable in view of the price. Other manufacturers should follow this example.
