Asus ZenBook Flip 14 UX461UA (i5-8250U, SSD, FHD) Convertible Review

Sascha Mölck, Felicitas Krohn (translated by Mark Riege), 03/29/2018

Versatile. TThe ZenBook Flip 14 pleases with a fashionable metal case, an illuminated keyboard, and a good battery life. Not only can the touchscreen be operated with your fingers but also using the input pen which Asus sells separately. However, in terms of the equipment, Asus has made a few decisions that are questionable.

The ZenBook Flip 14 UX461UA is a slim and compact convertible with a 14-inch screen. Asus has managed to pack all of the technology into a case that has the dimensions of a 13.3-inch device. The computer is driven by a ULV quad-core processor. The competitors include devices such as the Dell Inspiron 13 5379, the HP Spectre x360 13, and the Lenovo Yoga 920-13IKB.

Case - The ZenBook Flip offers a fashionable metal case

Asus has selected  a slim, silver metal case for the ZenBook Flip 14. Only the display bezels are kept in black color. The top of the base unit has a matte finish, and the back of the lid is decorated with a circular brush pattern. The battery is built-in. The Flip 14 does not offer a maintenance hatch and therefore you will have to open the case in order to access the parts inside. More on that later.

The workmanship of the device offers no cause for complaints. The gap widths are correct and there are no noticeable metal protrusions. In terms of stability, the case shows no grave weaknesses. For example, the case can be bent slightly on the left, next to the keyboard and below the touchpad - but this is also the case for most notebooks/convertibles. Even though the base unit can be twisted slightly, this remains within limits. The same can be said about the lid. If you put pressure on the back of the lid, there are some noticeable changes in the image display in some places.

When the lid is opened, the bottom of the lid serves as an additional foot. Then the back area of the base unit is raised and does not touch the surface anymore. The hinges keep the lid tightly in position. You can open the lid with one hand if you use some finger, hand, and arm acrobatics.

Asus has fitted a 14-inch display into a case that has the dimensions of a 13.3-inch device. So the device turns out quite compact and plays at the same level as "real" 13.3-inch devices. The HP Spectre x360 13-ae048ng turns out even significantly slimmer than the competition.

Equipment - Asus only offers standard fare in the Flip 14

Asus does not offer any surprises in terms of the connections. You can connect an external display via HDMI. All three USB ports (2x Type A, 1x Type C) support the USB 3.1 Gen-1 standard. The Type-C port only serves for data transfer, and you cannot charge the battery via Type-C USB, for example. We had expected more here. The price level of the convertible demands for at least one Type-C USB 3.1 Gen-2 port, and it should rather be a Thunderbolt-3 port.

SD Card Reader

Asus does not offer a full SD card reader in the ZenBook, but we have to make do with a microSD reader. The built-in model is not one of the faster ones of its kind. When copying large data blocks, it achieves a maximum transfer rate of 36.5 MB/s. The transfer of 250 JPG image files (around 5 MB each) is performed at a speed of 33.2 MB/s. The HP Spectre x360 13, which is also equipped with a microSD card reader, proves that significantly higher transfer rates would be possible. We are testing the card reader using a reference card (Toshiba Exceria Pro M501 microSDXC 64GB).

Communication

The ZenBook Flip does not offer an Ethernet port. Anyone needing such a port will have to use a corresponding USB adapter. The built-in WLAN module uses an Intel chip (Dual Band Wireless-AC 8265), which in addition to the 802.11a/b/g/n WLAN standards also supports the fast ac standard. The transfer rates that we measured under optimal conditions (no additional WLAN devices in close proximity, close distance between notebook and server PC) turned out well.

Webcam

The webcam is not convincing. It produces washed out images at a maximum resolution of 1280x720 pixels.

Accessories

As well as the customary information leaflets (warranty information, quick start manual), the box of the convertible also includes a bag.

Maintenance

The ZenBook does not offer a maintenance hatch. In order to access the insides, you will have to remove the bottom of the case. The process is not particularly difficult. In order to do this, you will need to remove all the screws on the bottom of the case. There are no hidden screws underneath the rubber feet. After that, you can remove the case bottom using a spatula. You can access the fan, the SSD, the WLAN module, and the battery. There are no memory slots, but the memory is soldered-in.

Warranty

Asus offers a two-year warranty for the convertible - including pickup service. There is an option to extend the warranty. For example, you have to pay about 90 Euros (~$112) for a three-year warranty. Please see our Guarantees, Return Policies and Warranties FAQ for country-specific information.

Input Devices - The touchscreen of the Asus convertible accepts pen input

Keyboard

The ZenBook Flip is equipped with an illuminated chiclet keyboard. The flat, smooth keys have a short stroke and a clear pressure point. However, the resistance could have been crisper. While typing, the keyboard has a slight give - more in the center than at the edges. Even though this did not interfere much, this should not happen in a device of this price range. The illumination has three brightness levels among which you can choose using two function keys. Overall, Asus delivers a decent keyboard for home use here, but prolific writers should choose another device.

Touchpad

The multi-touch capable ClickPad takes up an area of about 10.5 x 7.3 cm (~4.1 - 2.9 in). This offers a lot of space for navigation using gestures. The smooth surface of the pad makes sliding the fingers easy. The pad has a short stroke and a clear pressure point. There is a fingerprint reader in the top right corner of the ClickPad.

Input devices

Touchscreen

The touchscreen of the ZenBook supports 10 touch points. It did not give us any problems and reacts promptly to the inputs. The screen can be operated with fingers as well as the Asus Pen, which needs to be purchased separately for about 50 Euros (~$62).

Display - The contrast of the ZenBook Flip 14 display is too low

The 14-inch touchscreen display of the ZenBook Flip has a native resolution of 1920x1080 pixels. The brightness (288 cd/) and particularly the contrast (530:1) are too low, considering the price level. We are expecting values beyond 300 cd/ and 1000:1 here.

Unfortunately, the display uses PWM at a low frequency of 200 Hz to control the brightness at 90% or lower. This can lead to headaches and/or eye problems for sensitive persons.

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 9689 (minimum: 43 - maximum: 142900) Hz was measured.

The color reproduction in the state of delivery can be called acceptable. We register a DeltaE 2000 color deviation of 5.17. This is not too far from the target range (DeltaE smaller than 3). The display does not suffer from a blue tint. The display is unable to reproduce the AdobeRGB and sRGB color spaces. The coverage rates measure 55% (AdobeRGB) and 85% (sRGB).

You can improve the color reproduction of the display by using the color profile we are offering. However, you need to make sure that you have the same display model (manufacturer + model number) as our test unit. Otherwise the color reproduction can become worse, instead of improving. Often displays from different manufacturers are used within the same notebook model series.

Performance - Asus has equipped the ZenBook convertible with mid-range hardware

With the ZenBook Flip 14, Asus delivers a 14-inch convertible which offers more than enough computing power for applications from the office and internet areas. Our test unit can be purchased for about 950 to 1,000 Euros (~$1,178 - 1,240; The Asus ZenBook Flip 14 UX461UA is available for about $900 in the US). Other model variants are also available.

Processor

The ZenBook is driven by an Intel Core i5-8250U (Kaby Lake Refresh) quad-core processor. This is a mid-range CPU that strikes a good figure in all application areas. The built-in ULV processor (TDP: 15 watts) supports Hyperthreading, which means that two threads per core can run simultaneously. It operates at a basic clock speed of 1.6 GHz which can be increased up to 3.4 GHz via Turbo.

The processor runs through our multithread CPU tests at 1.3 to 3.4 GHz in mains operation. The single-thread tests are mostly run at 3.4 GHz. At times, one core is throttled down to 2.4 to 2.8 GHz. In battery operation, Turbo is not used, and the CPU tests run at 1.4 to 1.6 GHz (single thread) and 1.8 GHz (multithread).

We test whether the Turbo can also be used continuously in mains operation by running the multithread test of Cinebench R15 for about 30 minutes in a continuous loop. From the first to the second run, the result drops by about 5%. In successive runs, we also observe a drop - however, then the results drop considerably slower. In other words, the average Turbo speed drops with each successive run.

Cinebench R15 CPU Multi 64 Bit

The results in the CPU tests we ran remain on a normal level for the processor used here. In the multithread applications, the Turbo speed fluctuates significantly. This does not surprise us, since the cooling options are limited in a slim and compact convertible such as the ZenBook.

The additional cost for a ZenBook model with a Core-i7-8550U processor would not be worthwhile for most users. First, the moderate performance gain would be outweighed by a significant premium and second, the Core i7 would not be able to use its full performance, or only use it for a very short time as is the case here.

System Performance

The combination of Core-i5 processor, working memory running in dual-channel mode, and Solid-State Disk ensures a smooth running system. We did not encounter any problems. The computer has more than enough performance for applications from the office and internet areas. The very good results in the PC-Mark benchmarks confirm this. An increase in performance would not be possible, since Asus has already maxed everything out.

Storage Solution

Asus has equipped the ZenBook with a SATA-III SSD from SanDisk. This is a model in the M.2-2280 format, which offers a total capacity of 256 GB. Of that, about 205 GB are available to the user at the time of delivery. The remaining storage space is used by the Windows installation and the recovery partition. The transfer rates turn out to be good.

According to the Asus website, there are also ZenBook models that are equipped with NVMe SSDs. So there should be an option to replace the SSD used in our test unit with an NVMe model. These Solid-State Disks run at considerably higher transfer rates, since they are connected via PCI Express x4 3.0.

Gaming Performance

The CPU-GPU combination of the ZenBook Flip can bring some games smoothly to the screen. However, you must limit yourself to low resolutions and low quality settings. And this goes only for games that have moderate demands on the hardware. Power hungry games such as "Final Fantasy XV" cannot be played under any circumstances. Thanks to the working memory running in dual-channel mode, the frame rates turn out higher than in comparable devices whose memory runs in single-channel mode.

Emissions

Noise Emissions

The fan of the convertible does not produce a particularly high noise level. During idle operation, it is mostly silent or runs at a very low speed. Under load, it does not rev up excessively. During the stress test, we measured a noise level of 35.9 dB(A).

Unfortunately, the ZenBook produces some background noises: If you listen closely, you can hear a constant electronic crackling with varying intensity coming from inside. However, while idling or under low loads, you need to put your ear close to the device in order to hear the crackling at all. But under load, you can sometimes even still hear it clearly while the fan is running - for example, while running the Cinebench benchmark.

Temperature

The ZenBook in the stress test
The ZenBook in the stress test

The ZenBook runs through our stress test (Prime95 and FurMark run for at least one hour) in the same way in mains and battery operation. The processor begins the test at 1.3 - 1.6 GHz, and then the speed drops to 1.2 - 1.4 GHz. At the beginning of the test, the graphics core runs at 700 - 900 MHz, and later the speed levels out at 800 MHz.

The heat development of the convertible remains within limits. During the stress test, the 40-degree Celsius mark (104 °F) is only exceeded at two measurement points.

Battery Life

The ZenBook Flip 14 does not lack endurance. In our practically relevant WLAN test, the Convertible achieves a runtime of 9:26 h. Here, we simulate the load while opening websites via a script. The "Balanced" power profile is active, the power saving functions are deactivated, and the display brightness is lowered to about 150 cd/m². The 14-incher lasts for 8:33 h in our video test, where we run the short film "Big Buck Bunny" (H.264-coding, 1920x1080 pixels) in a constant loop. The Wi-Fi module as well as the power saving functions are deactivated, and the display brightness is set at about 150 cd/m².

The battery has a 57 Wh capacity.

With the ZenBook Flip 14, Asus has a convertible in its offerings whose 14-inch screen has been fitted into a case that has the dimensions of a 13.3-inch notebook. So this is a slim and compact device. The computer is run by a ULV quad-core processor which offers more than enough processing power for application from the office or internet areas.

A Solid-State Disk ensures a smooth running system. This could be replaced by an NVMe model if necessary. However, in order to do this, you would need to open the case of the notebook.

Despite its price of almost 1000 Euros (~$1240), the ZenBook Flip 14 still leaves room for improvement.

The battery life turns out very good. This is accompanied by a decent keyboard, which fulfills the demands of home usage. The keyboard illumination is also a positive. The display does not trigger any storm of enthusiasm. The brightness and particularly the contrast would need to be higher - the price level of the convertible demands it.

We see the Type-C USB 3.1 Gen-1 connection as unsuitable, since it can only be used for data transfer. We would have at least expected that the battery of the notebook could be charged via Type-C USB. After all, this is a mobile device. In principle, Asus should have put in a Thunderbolt-3 connection. In addition, Asus has only equipped the ZenBook Flip with a microSD card reader that does its work rather leisurely. 

Finally, we should mention the electronic crackling of our test unit, which is produced by the convertible in varying intensity. This also should not happen in a device of this price range.
