MagyarAsus VivoBook Flip 14 TP412UA (i5-8250U) Convertible Review
The Asus VivoBook Flip 14 TP412 directly succeeds last year's VivoBook Flip 14 TP410 with a fair number of changes in tow. Announced in June, the convertible only began shipping earlier this month for a starting price of under $700 USD for the base Core i3 configuration.
Our test unit today is the mid-range Core i5 SKU with 8 GB of RAM and 256 GB of storage for $750 USD. The highest-end option includes a Core i7-8550U with double the RAM and up to 1 TB of storage. The 1080p touchscreen and integrated graphics are otherwise identical across the entire lineup.
The mainstream VivoBook series sits just below the flagship ZenBook series to appeal to users on a tight budget. Thus, it directly competes with other sub 15-inch mainstream convertibles like the Lenovo Yoga 530, Acer Spin 3 SP314, Samsung Notebook 7 Spin, Dell XPS 13 9365, or Dell Inspiron 13 5000 2-in-1. Pricier flagship convertibles are also available in this size category such as the ZenBook Flip 14, Lenovo Yoga 920, and HP Spectre x360 13.
We recommend checking out our review on the last generation VivoBook Flip 14 TP410 as it still shares many similarities with this latest iteration.
Case
Asus has managed to cut the thickness down from 19 mm on last year's TP410 model to 17.6 mm on this year's TP412 model. The newer design is just a hair lighter and smaller as a result without sacrificing any of the connectivity features of the previous model.
The matte chassis leaves a good first impression with no unintended gaps or uneven crevices. The aluminum outer lid is smooth and more rigid than even the lid of the Yoga 920. Meanwhile, the plastic base is slightly textured with a comparatively cheaper feel. Slight but visible flexing is possible when attempting to twist the front edges or warp the center of the keyboard deck. The flexing is not enough to be a concern during regular use, but it cements the TP412 as a mainstream offering instead of a flagship Zenbook.
The hinges are the weakest aspect of the chassis as they could have been more taut to reduce teetering of the lid. Overall, system rigidity is a step below the Spectre x360 13.
Connectivity
The ports are essentially identical to last year's TP410. The Kensington Lock has been moved from the left edge to the right edge, but nothing else has changed. We're hoping that Asus will drop the proprietary AC adapter port altogether for USB Type-C charging similar to the ZenBook 3 UX390.
SD Card Reader
The integrated SD card reader is slow with a transfer rate of only 28 MB/s with our UHS-II test card. Moving 1 GB worth of images from our card to desktop takes over 40 seconds compared to 6 or 7 seconds on the Spectre x360 15.
A fully inserted SD card still protrudes by over half its length. Be sure to remove the card first for safer transporting.

Communication
The Intel 8265 module has not changed for theoretical transfer rates of up to 867 Mbps. While we experienced no issues when browsing the net, we noticed that connectivity was not always steady. An iPerf test revealed that transfer rates would sometimes fluctuate to under 100 Mbps once or twice every minute. We're unsure if this is widespread or something specific to our test unit.
Maintenance
Serviceability has improved significantly over last year's model. The bottom panel is relatively easy to remove with just a Philips screwdriver and sharp edge. The RAM slot is covered by an aluminum cage and the secondary 2.5-inch SATA bay has been removed.
Accessories and Warranty
The box includes no extras other than the AC adapter, Quick Start guide, and warranty card. The standard one-year limited manufacturer warranty applies. Please see our Guarantees, Return policies and Warranties FAQ for country-specific information.
Input Devices
Keyboard
The keyboard keys (~27.0 x 10.5 cm) are adequate if not slightly on the spongy side. The Backspace, Enter, and Arrow keys in particular are softer than we are used to. Clatter is moderate and close to the keys of the XPS 13.
The three-level white backlight returns. Unlike on the TP410, however, Asus has flipped the F function keys with their secondary multimedia functions. Thus, the fn key is no longer required to adjust volume, brightness, or keyboard lighting.
Touchpad
The Precision clickpad surface (~10.6 x 7.5 cm) is responsive with smooth gliding properties. If moving very slowly, however, the finger tends to stick and skip. Its integrated mouse clicks are also shallow in travel and could have benefited from stronger feedback.
Display
Asus has unfortunately downgraded the display for the TP412. Whereas last year's TP410 utilized an IPS panel from Chi Mei, the new TP410 uses an IPS panel from AU Optronics with inferior gamut and contrast and a dimmer backlight as shown by our table below. It could have been a cost-saving measure, but it's a very disappointing find nonetheless.
Luckily, the glossy touchscreen is still crisp and free of grains. We can detect no pulse-width modulation and backlight bleeding is minimal around the corners of our unit.

Color space covers only 59 percent and 38 percent of the sRGB and AdobeRGB standards, respectively, to indicate a budget panel. Costlier Ultrabooks like the Zenbook or Lenovo Yoga often cover sRGB almost fully for deeper and more accurate colors.
Further display measurements reveal accurate grayscale and colors which we were not expecting from a budget-mainstream system. Our calibration attempts improve the display only marginally. Colors still become increasingly more inaccurate at higher saturation levels due to imperfect sRGB coverage.

Outdoor visibility is poor despite the flexible 2-in-1 design. The dim display and glossy backlight only accentuate glare. Viewing angles are otherwise very wide with no major color shifting as one would expect from an IPS panel.
Performance
Current SKUs can be configured with a Core i3-8130U, i5-8250U, or i7-8550U while the integrated Intel GPU remains fixed. These ULV CPUs cater to light office or home users where word processing, browsing, streaming, and multi-tasking take priority. Performance users or video editors may want to consider laptops with more powerful Intel Core H-class CPUs such as the Zenbook Pro 15 series.
Processor
CPU performance is where we expect it to be for a Core i5-8250U. The Kaby Lake-R processor is roughly 60 percent faster than the Kaby Lake Core i5-7200U in last year's TP410 for a performance level very similar to the Core i5-7300HQ. Users upgrading from the Core i3-8130U option should see a notable performance boost of about 54 percent.
Running CineBench R15 Multi-Thread in a loop reveals a performance drop of only 7 percent over time. This suggests that the system is unable to maintain maximum Turbo Boost clock rates indefinitely when under very high stress. Such a behavior is not unexpected from super-thin laptops.
See our dedicated page on the Core i5-8250U for more technical information and benchmark comparisons.
System Performance
Our PCMark 10 score is 16 percent higher than the last generation TP410 to indicate a small year-over-year performance boost. Pricier and more powerful convertibles, such as the Yoga 920, will still outperform the TP412.
Our test unit suffers from sleep and wake issues. When setting the system to sleep, it would always reboot instead of waking up properly. There appears to be no update to address the issue at the time of writing.

Storage Devices
Whereas the TP410 had two internal drive options (M.2 + 2.5-inch SATA III), the TP412 has only a single M.2 drive. The 256 GB Micron 1100 MTFDDAV256TBN drive in our test system is average for a SATA III SSD if not slightly slower in sequential read and write rates.

GPU Performance
The integrated UHD Graphics 620 holds no surprises as it very common amongst laptops less than two years old. Raw GPU power is about 22 percent higher than the HD Graphics 620 in last year's TP410 and almost 35 percent slower than the old GeForce 940MX. In practical terms, GPU performance is still lackluster for anything more demanding than streaming or light gaming.
See our dedicated page on the UHD Graphics 620 for more technical information and benchmark comparisons.

Stress Test
We stress the notebook with synthetic loads to identify for any potential throttling or stability issues. When running Prime95, the CPU can be observed operating at 3.2 GHz for the first few seconds until reaching a core temperature of 95 C. Thereafter, clock rates quickly drop to a stable 2.3 GHz in order to maintain a cooler core temperature of 73 C as shown by our screenshots below. When considering that the base clock rate of the Core i5-8250U is 1.6 GHz, the system's ability to maintain a +700 MHz Turbo Boost is admirable. Running both Prime95 and FurMark simultaneously will throttle performance even further.
Running on battery power will not impact CPU or GPU performance. A 3DMark 11 run on batteries returns Physics and Graphics scores that are within just 1 percent of the scores when running on mains.

System Noise
The system fan is always active no matter the onscreen load. When idling on desktop, however, fan noise is so low that our microphone cannot detect it 15 cm away; you'd have to place an ear on the keyboard to hear the slight whir. The system is essentially silent when word processing or streaming.
Higher loads like gaming may induce a fan noise of 35 dB(A) to 39 dB(A) not unlike on the TP410.

Temperature
Surface temperatures are warmest near the center of the notebook due to the positioning of the processor and heat sink underneath. When under very high loads, the top and bottom hot spots can become as warm as 37 C and 48 C, respectively. The system never becomes uncomfortably warm when streaming or word processing, but take care to not cover the small ventilation grilles along the bottom.
(+) The maximum temperature on the upper side is 36.6 °C / 98 F, compared to the average of 35.3 °C / 96 F, ranging from 19.6 to 55.7 °C for the class Convertible.
(-) The bottom heats up to a maximum of 49.4 °C / 121 F, compared to the average of 36.7 °C / 98 F
(+) In idle usage, the average temperature for the upper side is 24 °C / 75 F, compared to the device average of 30.2 °C / 86 F.
(+) The palmrests and touchpad are cooler than skin temperature with a maximum of 22.2 °C / 72 F and are therefore cool to the touch.
(+) The average temperature of the palmrest area of similar devices was 28.2 °C / 82.8 F (+6 °C / 10.8 F).
Speakers
The stereo speakers are surprisingly loud for the size with no static and minimal chassis reverberation. Bass is weak and earphones are recommended for video or music playback.

Energy Management
Power Consumption
When idling, the TP412 is more efficient than the TP410 which could explain its longer battery life in the next section. Otherwise, consumption is similar to other Ultrabooks with the same Core i5-8250U or i7-8550U CPU.
The very small (~5.2 x 5.2 x 2.8 cm) 45 W AC adapter is sufficient for the power profile of the system.

Battery Life
Battery capacity has not increased from last year's TP410. Despite this, runtimes are now much longer by over two hours when subjected to the same WLAN loads. A reduction in background activity could be a likely culprit.
Charging from near empty to full capacity takes a little over two hours.

Pros
Cons
Verdict
The 2018 VivoBook Flip TP412 is both a few steps forward and a few steps back compared to its immediate predecessor. Its Kaby Lake-R update is indubitably faster while being thinner, lighter, and longer-lasting for a more attractive package overall. Unfortunately, its display is dimmer, its gamut is narrower, and it's missing the secondary 2.5-inch SATA bay that was present on the TP410.
For a retail price of $700 to $800, the TP412 is a compelling 14-inch convertible without any of the fancy features of pricier models. Its versatility makes it good for indoor and classroom use while its dim display makes it poorer for outdoor conditions.
Fair for the price. The VivoBook Flip TP412 doesn't offer anything above its price range to make it a must buy for mainstream users. Hopefully, future iterations will brighten up the glossy display to improve outdoor visibility.
