Asus ZenBook 14 UX433F (i7-8565U) Laptop Review

All screen. The new ZenBook 14 has a mind-boggling 92 percent screen-to-body ratio to best even the XPS 13. How did Asus manage to achieve such narrow bezels on all four sides of the display while still offering 100 percent sRGB and Whiskey Lake-U?

Asus has been doubling down on narrow bezels at a quicker pace than many of its competitors. After launching the first 17-inch gaming laptop with narrow bezels a couple of months ago, the OEM is now ready to introduce a new ultrathin Zenbook series with narrow bezels on all four sides of the display. In contrast, the Spectre x360 13 and XPS 13 have narrow bezels on only two and threes sides of the display, respectively.

The new Zenbook family consists of 13.3-inch (UX333), 14.0-inch (UX433), and 15.6-inch (UX533) offerings that all share similar design features. We recommend checking out the original announcement here for a quick comparison between the UX333, UX433, and UX533.

Our unit under review today is the Zenbook UX433FA equipped with 8 GB of LPDDR3 RAM, a 1080p IPS display, 512 GB NVMe SSD, and the new Whiskey Lake Core i7-8565U CPU for $1200 USD. The CPU and display resolution are fixed while RAM can go up to 16 GB and storage can start at 128 GB. A GeForce MX150 GPU option is planned but not yet available at the time of writing. The Zenbook UX433 is a successor to the Zenbook UX430 and it's set to compete directly with alternatives like the 13.9-inch Huawei MateBook X Pro, 13.9-inch Lenovo Yoga C930, 14-inch Acer Swift 5, and 14-inch HP Pavilion 14.

Case

The UX433 chassis is visually striking and distinct when compared to other Ultrabooks because of the angled rear lid and narrow bezels along the bottom of the screen. The screen is narrow on all four sides without needing to alter the position of the webcam unlike on the XPS 13. Asus is claiming a very high 92 percent screen-to-body ratio compared to "only" 80.7 percent on the Dell.

In fairness, however, the angled rear lid is not new as it can also be found on the older HP Pavilion 15 Power. Furthermore, Asus managed to make the bottom bezel look narrower than it actually is by hiding a large portion of it behind the base when the lid is opened. Our screenshot below shows why Asus couldn't have used regular hinges for this particular design as it would have exposed more of the bottom bezel. It's a clever approach because users see a bottom bezel that's just 3.3 mm thick when the lid is opened.

Chassis quality is an improvement over the UX430. The relatively thick lid is more rigid than the flexible lids of the UX430, Yoga 920, LG Gram 15, or Samsung Notebook 9 while coming very close to the lid of the XPS 13 9360. Pushing down on the outer lid, palm rests, or keyboard center results in minor warping but no audible creaking. The base isn't quite as sturdy as a HP Spectre, but it's the closest we've seen yet from an ultrathin Zenbook.

The hinges are rigid enough to prevent teetering when typing. However, it could have been stiffer for improved longevity as we're unsure how the hinges will hold over time. The HP Spectre has the advantage yet again with its stronger hinges.

The narrow bezels on both the top and bottom edges of the display have an interesting side effect. The notebook appears wider than other 16:9 laptops since the chassis can afford to be shorter in depth. In fact, the length of the UX433 is exactly the same as on the XPS 13 despite the fact that the Asus has a larger 14-inch screen. Asus managed to shave off over 2.5 cm in length when compared to the last generation UX430 largely due to the trimmed bottom bezel.

The system still weighs about the same as many of its competitors since it is slightly thicker (15.9 mm) than the XPS 13 (11.6 mm), MacBook Air (15.6 mm), and Yoga C930 (14.9 mm). In other words, the UX433 has one of the smallest footprints for its size class even though it's not necessarily the thinnest.

Connectivity

Port selection has changed when compared to the UX430. The full-size SD reader on the last generation model has been replaced by a smaller MicroSD reader while the smaller Micro HDMI port on the UX430 has been replaced by a full-size HDMI port. USB Type-C returns albeit still with no Thunderbolt 3 support. 

We're disappointed to see a proprietary charging port yet again as a combo USB Type-C charger would have been more convenient. Competitors like the HP Spectre 13, Dell XPS 13, and Lenovo Yoga C930 have already moved on to USB Type-C charging.

SD Card Reader

The spring-loaded MicroSD reader is just as slow as the full-size reader on the UX430. Transferring 1 GB of images from our UHS-II MicroSD card takes 33 seconds compared to less than 7 seconds on the XPS 13 MicroSD reader.

A fully inserted MicroSD card protrudes by about 1 mm for easy ejecting and safe carrying.

Maintenance

The bottom panel requires both a T5 Torx wrench and a Philips screwdriver for the two hidden screws underneath the rubber footing. Servicing is easy if not slightly annoying because the rubber feet can be difficult to remove.

Upgrades are limited to the M.2 SSD as the WLAN and RAM modules are soldered. An empty slot underneath the heat pipe is reserved for a potential dedicated GPU even though there are currently no other GPU options for the UX433 as of this writing.

Internals are largely similar to the UX430

Accessories and Warranty

Asus throws in a free USB Type-A to RJ-45 adapter alongside the usual Quick Start guide and warranty card. Older Zenbook models, such as the Zenbook 3, included a free carrying case that we're sad to see missing for the UX433.

The standard one-year limited warranty applies.

Input Devices

Keyboard

The backlit keys have improved tactility over the UX430. The 1.4 mm travel is back compared to 1.3 mm on the HP Spectre 13 for a slightly deeper press. Feedback is uniform and slightly softer than on the Spectre or EliteBook x360 1030, but still firm enough for a satisfactory typing experience with relatively quiet clatter.

The Directional keys are unfortunately small and spongy and there is no fingerprint reader available. 

Touchpad

The Precision trackpad (10.5 x 6.2 cm) is actually narrower than the trackpad on the last generation UX430 (10.5 x 7.5 cm). Nonetheless, glide is smooth and responsive with no sticking when moving at slow speeds.

The integrated click keys are soft and shallow with quiet clatter due to their spongy press. The clickpad the job done if an external mouse is not available, but we find it easier to simply tap on the surface to input a click instead. The trackpad on the competing MateBook X Pro does a much better job in this regard.

A unique feature of the new UX333/433/533 series is the backlit NumPad inspired by the NumPad on the Zephyrus GX501 gaming laptop. By pressing the top right corner of the trackpad, the trackpad surface becomes a virtual touch-sensitive NumPad. It's a clever approach especially for smaller laptops where there is no room for a dedicated NumPad.

In practice, the virtual NumPad is simply not as reliable as a dedicated NumPad because it lacks tactile feedback when tapped. Attempting to tap the numbers quickly will inevitably lead to missed values. Additionally, the brightness of the lit NumPad cannot be controlled and it's far too bright when working on a plane or dark room. It's certainly better than nothing, but adding brightness control and haptic feedback would have gone a long way to making the virtual NumPad more comfortable to use.

Display

The UX433 uses the same AU Optronics B140HAN03.2 IPS panel as found on last year's Acer Swift 5 SF514 and Acer Spin 7 SP714. Consequently, our Zenbook shares the many of the same display characteristics as these 14-inch Acer laptops. Contrast is excellent at over 1000:1 and colors are deep with crisp text and no graininess issues. A lighter matte panel SKU is planned, but there will be no touchscreen or 4K UHD options across all SKUs. This is a high quality panel that looks even better because of the narrow bezels. 

The maximum backlight brightness of about 309 nits is standard for most Ultrabooks and gaming laptops. Although not dim by any means, we were hoping for a brighter display just to one up the competition even further. The MacBook Pro 13 and Samsung Notebook 9, for example, are each over 60 percent brighter when on their respective maximum settings.

When compared to the BOE panel on the original UX430, the UX433 has faster response times for reduced ghosting and it doesn't suffer from pulse-width modulation. Slight uneven backlight bleeding is present along the top edge of our screen.

* ... smaller is better

Color space is approximately 89 percent and 58 percent of the sRGB and AdobeRGB standards, respectively, compared to Asus' claim of 100 percent sRGB. Results are similar to most mainstream Ultrabooks and just slightly better than on the UX430. Wider color coverage is available on the larger 15.6-inch Zenbook UX580 but not for the UX333/433/533 series.

Further measurements with a X-Rite spectrophotometer reveal an overly cool color temperature out-of-the-box with poor reproduction of Blue and Teal in particular. While this is to be expected from a cheap panel with limited color coverage, we're a bit surprised to see it here on a premier laptop. Our calibration addresses these issues and greatly improves color accuracy in the process. We highly recommend applying our ICC profile to get the most out of the display especially since the panel is capable of very accurate colors.

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↗ 14.4 ms rise
↘ 9.6 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. » 32 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (25.6 ms).
       Response Time 50% Grey to 80% Grey
39.6 ms ... rise ↗ and fall ↘ combined↗ 21.2 ms rise

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. » 43 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (41 ms).

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: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8933 (minimum: 43 - maximum: 142900) Hz was measured.

The glossy display makes for poor outdoor visibility as the backlight is not powerful enough to overcome glare. Working under shade is still the best option if outdoor use is unavoidable. The MateBook X Pro and XPS 13 9370 are equipped with brighter displays if outdoor visibility is priority.

Performance

The UX433 is one of the first notebooks to ship with a Whiskey Lake-U processor and while the new CPU series consists of i5-8265U and i7-8565U SKUs, the UX433 is currently only shipping with the i7-8565U. We suspect that future iterations will expand to include Core i5 and discrete GeForce options up to the MX150 GPU as well.

The 15 W Whiskey Lake-U targets the same Ultrabook audience as the preceding 15 W Kaby Lake-R series. Nonetheless, the base clock rates and L1/L2/L3 caches are exactly the same between the i7-8565U and older i7-8550U.

Monitoring programs like CPU-Z, GPU-Z, and HWiNFO are unable to fully recognize the new Whiskey Lake-U CPU as of this writing.

 

Processor

Is this new-fangled processor any faster than the Core i7-8550U that it replaces? CineBench benchmarks reveal the i7-8565U in our Asus to be just 6 percent faster than the i7-8550U in the last generation UX430 and slightly below that of the Core i5-8259U in the MacBook Pro 13. It's a minor performance upgrade at best especially when compared to the massive gen-to-gen performance boost that the Kaby Lake-R series brought to the table last year. Users upgrading from Kaby Lake or earlier processors will still see significant performance gains.

Running CineBench R15 Multi-Thread in a loop shows relatively stable performance over time. The initial score of 624 points eventually drops to about 586 points for a dip of only about 6 percent. While marginally better than the i7-8550U in the UX430, we were hoping for a higher initial score to help boost the system even further over its Kaby Lake-R predecessors.

See our dedicated page on the Core i7-8565U for more technical information and benchmarks.

System Performance

PCMark benchmarks rank our Asus within single-digit percentages of many of its competitors including the Yoga C930 and outgoing UX430. In other words, system performance is not significantly faster than last generation Kaby Lake-R options. The latest 2018 MacBook Air scores much lower than our UX433 due largely to its slower Core Y processor.

We didn't experience any software or hardware issues during testing.

Storage Devices

According to the official spec sheet for the 512 GB Western Digital SN520 SDAPMUW NVMe SSD, the drive offers a theoretical sequential read and write rate of up to 1700 MB/s and 1400 MB/s, respectively. Our own test with AS SSD returns read and write rates of only 1201 MB/s and 931 MB/s, respectively. Performance is nonetheless significantly faster than the SATA III SanDisk SSD in the UX430 while still trailing behind the Samsung PM961 and PM981.

Swapping out the sole M.2 SSD may void the manufacturer warranty as there is a warning sticker over the screw.

See our table of HDDs and SSDs for more benchmark comparisons.

GPU Performance

The Whiskey Lake CPU may be new, but the integrated UHD Graphics 620 is the same ol' GPU with no performance surprises to speak of. 3DMark scores are about 18 to 28 percent higher than the average UHD Graphics 620 in our database. When compared to its direct Kaby Lake-R predecessors in the XPS 13 9370 or Surface Pro 6, however, graphics performance is essentially identical.

See our dedicated page on the UHD Graphics 620 for more technical information and benchmark comparisons. It is unknown if the MX150 option for the system is the slower 1D12 variant or the full-power 1D10 variant.

Emissions

System Noise

The cooling solution is almost identical to its UX430 predecessor despite the vast changes to the rest of the chassis. The fan is active during low loads like browsing or streaming, but it is essentially inaudible when sitting at a normal distance. Higher medium loads will bump fan noise to 36 dB(A) compared to almost 42 dB(A) on the UX430 since the latter is equipped with dedicated GeForce graphics. Had our UX433 test unit included GeForce graphics, it would have been very likely to exhibit the same fan behavior as the UX430.

Fan noise is quiet overall if not a bit louder than many other iGPU-only Ultrabooks like the XPS 13 or Spectre 13 when under higher processing stress. Our unit suffers from slight-moderate electronic noise that can be heard when placing an ear near the keyboard.

The left half of the notebook will always be warmer than the right half due to the positioning of the CPU and design of the cooling solution. In this case, surface temperature behavior hasn't change very much when compared to the older UX430.

Hot spots can reach over 43 C or 45 C on the WASD keys and bottom plate, respectively, while the palm rests remain cooler. Users can expect a warm notebook when browsing, word processing, or surfing. A more symmetrical temperature gradient like on the HP Spectre x360 13 would have been preferable.

We stress the notebook to identify for any potential throttling or stability issues. When subjected to Prime95 load, we can observe a CPU clock rate as high as 3.9 GHz while core temperature slowly rises to 89 C. Once this threshold is reached, the clock rate begins to alternate between 2.0 GHz and 2.7 GHz in order to keep temperatures in check. Since the base clock rate of the i7-8565U is 1.8 GHz, the CPU in our Asus is able to maintain at least a 200 MHz Turbo Boost at all times when under extreme CPU stress. Our screenshot below shows this in action including the alternating clock rate pattern.

Running Prime95 and FurMark simultaneously to stress both the CPU and iGPU will throttle clock rates even further as the system struggles to satisfy the processing demands.

Running on battery power will impact both CPU and GPU performance. A 3DMark 11 run on batteries returns Physics and Graphics scores 6211 and 1745 points, respectively, compared to 7617 and 1979 points when on mains.

Speakers

The integrated stereo speakers are louder than on the 2017 Spectre 13 but with average bass reproduction. Higher frequencies are emphasized for an overall "tinny" audio quality that's common amongst small laptops. Higher volume settings do not introduce any static and will reverberate the palm rests just slightly.

Energy Management

Power Consumption

Perhaps the closest system we can compare the UX433 to in terms of power consumption is the 14-inch VivoBook Flip 14 since have 15 W TDP CPUs and no discrete graphics. Even with these constants, however, the VivoBook Flip 14 still comes out to be more power efficient under all tested conditions. Running 3DMark 06 demands 42 W from our UX433 compared to just 33 W on our VivoBook. The new model may be a bit faster, but it also draws a tad bit more power in the process.

The highest consumption we can record is 44 W from the very small (~5.4 x 5.4 x 2.8 cm) 45 W AC adapter. This maximum draw is unsustainable over long periods of extreme stress because the system eventually throttles as shown by our graph below. The alternating power consumption behavior mirrors our clock rate observations during the stress test above.

Battery Life

Battery capacity remains unchanged from the UX430. Nonetheless, battery life is excellent at over 10 hours of constant WLAN use to be comparable to the MateBook X Pro. Charging from near empty to full capacity is slow at about 2 to 2.5 hours compared to 1.5 hours on most competing Ultrabooks.

In review: Asus ZenBook 14 UX433FA
In review: Asus ZenBook 14 UX433FA

The Ultrabook market has been steadily growing in terms of options and it's becoming more challenging for OEMs to set themselves apart from one another. Even so, Asus is still managing to surprise us with unique features like the UX580 ScreenPad and now the four-sided NanoEdge bezels that give the UX433 a very small footprint for the 14-inch screen size. The new design is visually distinct and uniquely Zenbook while improving upon rigidity and connectivity from the last generation. It's an evolutionary upgrade that we've come to expect but with a defining characteristic that's both visually striking and ergonomic.

We especially appreciate that the UX433 includes anti-glare matte and glossy panel options and an eventual GeForce MX150 SKU. Most Ultrabooks have glossy displays only and are limited to slower integrated Intel graphics.

The weakest feature of the UX433 is CPU performance. It's not the speed that's disappointing, but it's how marginal of a boost Whiskey Lake-U provides over 8th gen Kaby Lake-R to the point where users will not likely notice any performance gains. Even Asus knows this as the official UX433 product page is comparing Whiskey Lake-U to 7th gen Kaby Lake instead of 8th gen Kaby Lake-R in order to advertise a larger jump in CPU power. We can't help but feel that the system could have been cheaper and just as fast had it shipped with the i7-8550U or i5-8250U instead.

For future iterations, we'd like to see Thunderbolt 3 and a brighter display to better compete against popular alternatives like the XPS 13, MateBook X Pro, MacBook Pro 13, Samsung NP900, and others that may be easier to see in an outdoor setting. Asus should move away from the proprietary AC adapter port and adopt the more versatile USB Type-C charging as well. Haptic feedback for the virtual NumPad, a fingerprint reader, and a spill-proof keyboard are just a handful of missing features the manufacturer could consider to make the  UX433 an even better value.

A visual and quality upgrade from the last generation UX430. The system feels strong for the size even though it omits some features commonly found on other ultrabooks in its price range. The boost in CPU power from Whiskey Lake-U will be much greater if users are upgrading from laptops that are at least two or three years old.

After graduating with a B.S. in environmental hydrodynamics from the University of California, I studied reactor physics to become licensed by the U.S. NRC to operate nuclear reactors. There's a striking level of appreciation you gain for everyday consumer electronics after working with modern nuclear reactivity systems astonishingly powered by computers from the 80s. When I'm not managing day-to-day activities and US review articles on Notebookcheck, you can catch me following the eSports scene and the latest gaming news.
