Asus ZenBook Pro 15 UX535 laptop review: It could still be a little more Zen
The ZenBook Pro series is Asus's high-end subnotebook series. The Asus ZenBook Pro 15 UX580GE, which is already two years old, is the direct predecessor with a ScreenPad. The Pro Duo models that feature an even larger second display were released a year ago. Asus is now taking a step back again in terms of the ScreenPad size; otherwise, there's a new CPU-GPU combination. Since there's a lack of competition with the same unique selling point (ScreenPad), we make do with the multimedia laptops listed below, which otherwise have a similar hardware configuration. Apart from that, we also include the ZenBook 15 UX534 sibling model in our comparison.

Case - Revised aluminum unibody
The dark case of the UX535 is made almost entirely of metal and has been completely redesigned. It's similar to that of its sibling model, but it has more ventilation slots and other connections. The display's frame also manages to completely do without plastic, and the NanoEdge panel is made entirely of glass and is set directly into the aluminum frame. The base and display lid are, therefore, very stable and resistant to torsion. Bending the base requires a lot of effort, and this only leads to minimal crackling and creaking noises. Workmanship is generally at a high level; we didn't find any noticeable gaps.
The design pleases with its noble simplicity. With its sandblasted round structures, the dark aluminum surface almost looks like a classy record. The delicate, sand-colored "ZenBook Series" lettering in the center of the hinge is also nice. An asymmetrically placed silver ASUS logo decorates the top. However, fingerprints and grease stains remain clearly visible on the surface.
On the inside, the palm rests are slightly higher than the keyboard, which has a kind of bevel at its lower edge, making it more deeply embedded.
The ZenBook isn't really light due to its stable metal case; the ThinkPad X1 Extreme or even its own sibling model are much lighter. However, the rest of the competition is similarly heavy. In contrast to its predecessor, the 15-inch laptop has shrunk a bit.
Except for the sibling model as well as the Dell XPS 15, all competitors are a bit larger, so the UX535 places itself in the middle.
Connectivity - Stingy ZenBook subnotebook
The ZenBook is sparsely equipped for a 15-inch device. It only provides two USB ports, one of them Type-C with Thunderbolt 3 and charging function. We find this to be clearly too little! At least there's a full-fledged SD reader. A LAN port is absent once again. In spite of the few ports, they are still positioned quite close together; especially the HDMI and the USB-A port are very close to each other.
SD card reader
The performance of the card reader corresponds to the class average but nothing more. In combination with our 64 GB Toshiba Exceria Pro UHS-II SDXC, the competition is sometimes much faster.

Communication
A connection for a LAN cable isn't available, so you have to resort to WLAN if you don't have an adapter. While the transmission performance is very good, the reception performance is a bit below the expectations of the AX201 module. Nevertheless, the values are significantly better than the multimedia class average.
Webcam
You can use the infrared webcam to log in via Windows Hello, but the images provided by the 720p camera are still only average.
Security
Besides the aforementioned infrared camera for logging in via Windows Hello, TPM 2.0 is also on board; otherwise, there is neither a fingerprint scanner nor a Kensington slot or any other security features.
Accessories
Asus doesn't include any accessories; at least a USB LAN adapter would have been welcome.
Maintenance
There's no maintenance hatch, and the removable bottom cover is secured by 11 Torx screws. These have three different lengths, so you should take note of which screw belongs to which position. Unfortunately, Asus still hides two screws under the rear rubber feet, the latter are glued to the chassis, making it unnecessarily difficult for the customer to open the ZenBook. The hidden screws also have a different profile. If you dare, you will then have access to the battery, the fan and the SSD.
Warranty
Asus grants a 24-month warranty.
Input devices - Display integrated into the touchpad
Keyboard
The so-called ErgoLift hinge lifts the keyboard towards the display, which is supposed to provide a more ergonomic typing experience, but this also leads to potential scratches on the table. The keyboard's layout looks very tidy; the labels are clear, and the three-stage backlighting is helpful in the dark. The keys' surfaces feel a bit roughened, which initially takes some getting used to, since fingers don't glide away quite as smoothly on them.
The arrow keys are half the usual height. The power button is integrated as a key in the upper right corner, but mistakes rarely occur because important functions like home, end, etc., are not located nearby as usual but on the arrow keys instead.
The keys themselves have a medium travel and emit a clear feedback, so that typing is easy on the whole. The typing volume is okay, but there are definitely quieter models.
Touchpad
The touchpad is also a second display with useful and configurable functions as well. The pad itself is very wide (approx. 13 x 6.5 cm) and has a glass surface with very good gliding properties. Fingers glide smoothly even when they're moved very slowly. The integrated mouse buttons are triggered reliably.
If you don't know any better, you might think that the gliding zone is a normal touchpad, because the background remains dark as usual when the touchpad is deactivated. But you can turn the display on with F6 and benefit from a second display as a result. However, this causes the touchpad function to be lost. So you should also have a mouse at hand, and the touchpad can still be shown in display mode.
The display is still quite grainy and not uniformly bright due to the matte surface. But unlike its predecessor, the interface has now been revised. You don't have to move a cursor anymore, and the display can be operated like a completely normal touchscreen.
The display contains shortcuts to start the most frequently used apps, but you can also drag apps completely into the ScreenPad, making it an extended display for the main screen. Asus also works together with third-party manufacturers so that their software can offer special functions in combination with the ScreenPad. Consequently, users benefit from additional control options via the ScreenPad when using some video and audio editors. All in all, we find the pad to be very successful and would like to see this function integrated by more manufacturers so that more developers can adapt their software to it as well.
Touchscreen
The ZenBook Pro is full of handling possibilities, because the display can also be controlled using touch gestures. Typing on the screen is very precise and proved to be easy in the test.
Display - 4K with touch
The display comes from BOE. It's an IPS touchscreen panel with 4K resolution. The average brightness is quite good at 375 nits, but its distribution isn't excessively even at 84%. The center of the screen is much brighter than the edges at over 400 nits.
The pixel grid is clear, and screen bleeding is so minimal that it actually isn't noticeable even in dark settings.

* ... smaller is better
The black level is also only average at best, but the 4K displays found in competitors that are even more expensive can't do any better. In return, the Dell and Lenovo devices have slightly better contrast overall, but 1,149:1 is also adequate. All in all, the display is better than that of the predecessor, but some competitors do it even better.
The display is already well calibrated out of the box, and the color deviations are only minimal.
The monitor is also suitable for professional applications; in our test, the display covers the sRGB color space completely and the AdobeRGB one to 64%.
Outdoors, you should find a place in the shade because of the reflective surface, but due to the good brightness, most details can still be recognized when looking directly at the display. However, you should avoid oblique viewing angles or sunlight.

The viewing-angle stability of the 4K panel is quite good; even when viewed from extreme angles, only little brightness is lost, and the screen contents are still clearly visible.
Performance - No performance stability
Its Intel Core i7 of the Comet Lake series, the GTX 1650 Ti Max-Q, the 16 GB of RAM, and the 1 TB SSD qualify the ZenBook as a perfect multimedia all-rounder, and thanks to the good color-space coverage of the display, the laptop is also aimed at content creators, namely creatives and professional photo and image-editors. The built-in ScreenPad provides additional control options during editing and further emphasizes the potential target group.
Processor
Asus uses an Intel Core i7-10750H from the Comet Lake series. The CPU has six cores with clock speeds ranging from 2.6 to 5 GHz, and it can also process 12 threads simultaneously. The maximum boost clock speed for all cores running simultaneously is 4.3 GHz.
Our 30-minute Cinebench R15 loop reveals a strong performance fluctuation for the ZenBook that is many times higher than on the competition. The initial value is very high under little load; naturally, this value drops after the first two to three passes. However, performance never really stabilizes, but it fluctuates strongly until the end instead. Performance differences of over 10% can occur between two runs.
But on average, the CPU performs as it should. The Ryzen in the Acer Nitro is stronger, but the sibling model with a weaker CPU is significantly slower; the predecessor is about 38% behind.
On battery power, there's a performance loss of about 20%.

Just by simply opening the browser, the ZenBook already shows latency problems. The LatencyMon tool detects even higher latencies in combination with our 4K/60 Hz YouTube video. Once again, the Kernel Mode Driver Framework Runtimes causes the most problems, but it's also accompanied by the ACPI driver and an Nvidia driver.

Storage
The mass storage device is an SSD from Western Digital with a generous 1 TB capacity. It's ranked 12th in our SSD/HDD Benchmarks article, so it's a quite fast model. The test values confirm this, but the drive is still not quite as fast as the Samsung PM981 found in the sibling model or in the Lenovo ThinkPad X1.

Graphics card
The laptop can switch between the energy-efficient but weak Intel UHD Graphics 630 iGPU and the dedicated Nvidia GeForce GTX 1650 Ti Max-Q graphics card. The latter is an entry-level gaming card. The Max-Q design is a bit more power-efficient but also slower than the normal version.
In the 3DMarks, it remains slightly below an average 1650 Ti Max-Q (3 to 11%). However, the same GPU is about 3% slower in the sibling model.
A whole 35% of the 3D performance is lost on battery power as our repeated 3DMark 11 run reveals.

Gaming performance
Even though the GTX 1650 Ti Max-Q is more of an entry-level card for gaming, most titles can be played at Full HD and often even at high details. But the GPU is overwhelmed by the ZenBook's native 4K resolution.
All in all, the GPU also performs at the expected level, but most competitors without a Max-Q design are about 20 to 25% faster, which can be a big advantage. The predecessor is about 20 to 30% slower with its GTX 1050 Ti.

Emissions - Cool ZenBook Pro 15 UX535
Noise emissions
In idle usage, the fans are mostly at rest. They then turn up to an audible maximum of 42 dB(A) under load. The sibling model and the Lenovo laptop remain quieter here, but the devices from Dell and Acer as well as the predecessor are louder. Overall, the UX535 places itself in the middle in terms of volume.

Temperature
Everything remains cool in idle usage, and the same applies to the palm rests in every situation, even under stress. A maximum of 44 °C (~111 °F) is reached under heavy load, and the heat hotspot is located on the bottom side in the center towards the display. This is also a pretty good value in view of the surrounding cooler temperatures; except for the sibling model, all competitors get hotter under load and sometimes in a significant way.
(+) The maximum temperature on the upper side is 37.8 °C / 100 F, compared to the average of 36.9 °C / 98 F, ranging from 21.1 to 71 °C for the class Multimedia.
(±) The bottom heats up to a maximum of 44.2 °C / 112 F, compared to the average of 39.2 °C / 103 F
(+) In idle usage, the average temperature for the upper side is 25.8 °C / 78 F, compared to the device average of 31.3 °C / 88 F.
(+) Playing The Witcher 3, the average temperature for the upper side is 31.7 °C / 89 F, compared to the device average of 31.3 °C / 88 F.
(+) The palmrests and touchpad are cooler than skin temperature with a maximum of 29.6 °C / 85.3 F and are therefore cool to the touch.
(±) The average temperature of the palmrest area of similar devices was 28.8 °C / 83.8 F (-0.8 °C / -1.5 F).

The six CPU cores start the stress test at 4.2 GHz, which is close to the maximum Turbo clock speed for all cores running at the same time. However, the clock rate drops very early on; after one hour, it's still at 3.4 GHz but not consistently; in fact, performance oscillates between 3 and 3.6 GHz. The temperatures exceed 80 °C (~176 °F) very quickly. Afterwards, the clock rates are lowered. After one hour, the temperature rises to almost 90 °C (~194 °F).
The graphics card's clock speed also drops from the original 1.53 GHz to 960 MHz. This clock rate is by no means constant either, since it often fluctuates between it and a value that's up to 400 MHz higher. The temperature here is still a comfortable 77 °C (~171 °F).
The system recovers quite quickly, and a new 3DMark 11 run revealed no performance loss.
Speakers
The stereo speakers are, as is so often the case, not the greatest. At least the mids are quite well tuned, so that the sound is still alright. But the palm rests vibrate a bit when the volume is loud. However, the highs and naturally the basses in particular are, to put it mildly, improvable. The same applies to the maximum volume. Connecting external audio devices is advisable; the combined audio jack in addition to the HDMI and USB ports are available for this.
