Asus VivoBook Flip 15 TP510UA (i5-8250U, SSD, FHD) Convertible Review

Sascha Mölck, 👁 Sebastian Jentsch, Felicitas Krohn (translated by Martin Jungowski), 02/21/2018

Dark Display. Asus's VivoBook Flip 15 is equipped with a powerful quad-core CPU, a fast solid-state drive, a backlit keyboard, and features a touchscreen with support for Asus's optional stylus pen. Yet despite its price tag of around $900, it is not free of faults.

The VivoBook Flip 15 is a 15.6-inch convertible powered by a ULV quad-core processor with plenty of oomph. In addition to finger input, the touchscreen also supports a stylus pen sold separately for $50. Its main competitors are other convertibles such as the Dell Inspiron 15 5578-1777, the Acer Spin 5 SP515-51G, and the HP Envy x360 15m-bq121dx.

Case & Connectivity

The VivoBook’s case turned out particularly slender, and the notebook’s footprint is comparatively small for a 15.6-inch device. It is mostly made of plastic and aluminum, albeit only the display lid is composed of the latter. While the build quality was decent, rigidity was anything but: the base unit was pretty bendy and we would have wished for a more solid and rigid design. The device does not feature a maintenance hatch and the battery is not user-replaceable either.

In order to access the internal hardware, the case has to be taken apart almost completely. First, you have to undo all the screws at the bottom. There are no screws hidden underneath the rubber feet. Once the screws are removed, you have to flip the notebook back over on its feet and carefully remove the top cover with a spudger tool or a spatula. Watch out though: the top cover is attached with four ribbon cables to the motherboard. Once opened, you have access to the fan, the Wi-Fi module, the SSD, and the HDD. In order to access the RAM slots, the motherboard has to be removed completely.

There are no surprises when it comes to port availability. In addition to three USB Type-A ports (1x USB 3.1 Gen 1, 2x USB 2.0) the notebook also features a single USB Type-C (USB 3.1 Gen 1) port. The built-in SD card reader is rather lethargic and managed a maximum transfer rate of just 25.6 MB/s copying large chunks of data and 22.7 MB/s when copying 250 JPG files with around 5 MB each. The card reader was benchmarked with our 64 GB Toshiba Exceria Pro SDXC UHS-II reference card.

The Wi-Fi module is made by Intel (Dual Band Wireless-AC 8265) and supports the fast ac standard in addition to the usual 802.11a/b/g/n modes. Transfer rates were decent under ideal conditions (no other Wi-Fi devices within range, close distance between notebook and server).

Input Devices

The VivoBook is equipped with a backlit chiclet keyboard, including a number pad. However, since the case is slightly smaller than those commonly found on most 15.6-inch notebooks, the number pad has had to be reduced in size. The even and smooth keys feature a rather short key travel and well-defined feedback and accentuation. Unfortunately, the keyboard flexed somewhat while typing - unacceptable at the notebook’s price point. Keyboard backlight is controlled by two function keys, and a total of three brightness levels are available. All things considered the keyboard is decent for home users, but most certainly will not be an avid typist’s best friend.

The multitouch-capable ClickPad (10.5 x 7.3 cm/~4.1 x 2.9 in) is decently sized and large enough for gesture input. Its smooth surface makes it easy to use. The buttons offer short travel and clear and well-defined feedback and accentuation. A fingerprint reader is located in the top right corner.

The VivoBook’s touchscreen supports 10-point multitouch and never caused us any trouble or concern whatsoever. It can be used either with fingers or with an optionally available active stylus pen ($50) with support for 1024 different pressure levels.

The 15.6-inch touchscreen display’s native resolution is 1920x1080. Contrast ratio is quite decent (1527:1) but its average maximum brightness of just 221.3 nits is most certainly not. At this price point, we expect at least 300 nits or more. On a positive note the display did not show any signs of 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 9352 (minimum: 43 - maximum: 142900) Hz was measured.

Out of the box, DeltaE deviation for colors was measured at 5.03 (ideal: less than 3). We did not notice a blue tint on the display.

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
29 ms ... rise ↗ and fall ↘ combined↗ 15 ms rise
↘ 14 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 68 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (24.9 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. » 65 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (39.7 ms).

The VivoBook’s IPS panel features decent viewing angles, and the screen remained readable from all sides. Outdoor usability has been reduced significantly by the dark display, and the unit was only usable when the sun was not shining. The reflective layer over the display makes it even harder to use outdoors.

Performance

The VivoBook Flip 15 is a 15.6-inch convertible made by Asus. It offers more than enough performance for office and internet applications. Our review unit sells for a bit around $900 in Europe. At the time of writing, a second SKU was also available for sale in Europe. It features the exact same hardware specifications save for a dedicated GeForce 940MX GPU, and it costs $1000.

Processor

The VivoBook is powered by an Intel Core i5-8250U (Kaby Lake-R) quad-core ULV CPU with a TDP of 15 W and support for Hyperthreading (i.e. two threads per physical core). It clocks at 1.6 GHz with a turbo boost speed of up to 3.4 GHz.

Our Cinebench CPU benchmarks were completed at maximum speed on mains, and so were the single-thread CPU benchmarks on battery. Multi-thread CPU benchmarks on battery were performed at a clock speed of between 2.5 and 2.7 GHz. We saw similar behavior when running the Geekbench benchmarks.

Whether or not turbo boost can be upheld for sustained loads over long periods of time is determined during our 30-minute Cinebench R15 multi-thread loop. From the first to the fourth iteration scores dropped continuously and remained on that level of slightly below 700 points thereafter. While turbo boost is applied in this scenario it does not hit its theoretical maximum anymore.

System Performance

Overall system performance was fairly fast thanks to a solid-state disk and a powerful Core i5 processor. The more than decent PCMark benchmark results hint at a more than capable machine with enough performance for office and internet applications. Possible improvements include the addition of a second RAM module, thereby activating dual-channel mode for memory access.

Storage Devices

The main 128 GB m.2-2280 SATA III SSD is made by SanDisk. 88 GB is available out of the box; the rest is used up by the Windows operating system and the recovery partition. Transfer rates were very good.

A regular 2.5-inch hard drive was installed in addition to the SSD, and it offered an extra 1 TB of 5400 RPM storage.

Graphics Card

Video output relies on Intel’s integrated UHD Graphics 620 GPU. It supports DirectX 12 and runs at clock speeds of between 300 and 1100 MHz. 3DMark benchmark results were at a level expected of this GPU. The performance could have been slightly improved by enabling dual-channel mode, which would enhance an integrated GPU’s performance. This requires the installation of a second memory module.

Gaming Performance

Less demanding games can be enjoyed smoothly on the convertible. That said, they will require reduced resolutions and details in order to achieve acceptable frame rates, which can be further improved by enabling dual-channel mode.

Emissions & Energy

System Noise

The convertible remained comparatively quiet regardless of load. When idle, the fan even turned off completely every now and then, but ran at low revs most of the time. It can only be heard in particularly quiet environments, which is also true for the 2.5-inch hard disk drive. The fan revved up somewhat under load, and the maximum sound pressure determined during our stress test was no more than 34.2 dB(A).

Temperature

VivoBook during our stress test
VivoBook during our stress test

Our stress test (Prime95 + FurMark run simultaneously for at least one hour) was completed differently on battery and on mains. On mains, the CPU ran at 2.3 - 2.4 GHz while the GPU clocked at 700 - 750 MHz. On battery, turbo boost was not applied at all and the CPU ran at 1.6 GHz throughout the entire test. The GPU, on the other hand, ran at between 900 and 950 MHz.

The convertible remained very cool by and large. Some reading points exceeded the 30 °C (~86 °F) threshold during our stress test.

Power Consumption

Power consumption was at a level expected of a notebook such as this. Maximum power consumption when idle was 9.5 W, and topped out at no more than 33.3 W during our stress test (Prime95 + FurMark run simultaneously for at least one hour) due to neither CPU nor GPU running at full speed. The charger is rated at 45 W.

Battery Life

In our real-world Wi-Fi test we simulate opening websites with a script. The energy plan is set to “Balanced”, display brightness is normalized at 150 nits, and all energy saving features are disabled. With these settings, the VivoBook lasted for 5:58 hours.

Note that our review unit’s battery had already suffered a 6% battery health degradation. Devices with a battery health level closer to their initial design capacity should last a few minutes longer.

Verdict

Asus Vivobook Flip 15 TP510UA-E8073T. Review unit courtesy of cyberport.

The VivoBook Flip 15 is a compact and slim 15.6-inch convertible with plenty of oomph for office and internet applications thanks to its ULV quad-core processor. It stays cool regardless of load and remains very quiet most of the time.

It feels decently snappy thanks to its fast SSD, and its 1 TB 2.5-inch hard disk drive offers plenty of storage space. Both drives can be replaced and upgraded, albeit only after taking the case apart given that it lacks a dedicated maintenance hatch.

The keyboard is decent for home use and features a backlight. Battery life, as determined in our Wi-Fi test is only mediocre at best. An extra 30 minutes that might have in theory been possible with a brand-new non-degraded battery would not have had any influence on the notebook’s final score.

The IPS touchscreen offers a decent contrast ratio and wide viewing angles. However, its maximum brightness is too low. A notebook at the VivoBook’s price point has to be brighter no matter what. In addition to input by finger, the touchscreen also supports the optionally available Asus Pen ($50).

Price and Performance are disproportionate to each other.

Overall, the notebook has too many flaws for its high price of $900: the display is too dark, the keyboard flexes, and battery life is mediocre at best. To make matters worse the device only comes with a single memory module in single-channel mode and is thus not as fast as it could have been with two memory modules installed. Connectivity is pretty orthodox overall - a Thunderbolt 3 port would have certainly grabbed our attention. And last but not least, at a price of $900 the Asus Pen stylus should have been included.
