Asus ROG Zephyrus Duo 15 GX550LXS in Review: Unique Gaming Laptop with Lots of Performance Below the Hood

Display Duo. With its powerful hardware, the Zephyrus Duo manages to display the latest games smoothly on its matte 4K screen (IPS, Pantone-validated, 100% AdobeRGB, G-Sync). There are other great features as well: 2x NVMe SSD (RAID 0), 32 GB of RAM (in dual-channel mode), Thunderbolt 3. Additionally, the laptop comes with many accessories.
Sascha Mölck, 👁 Florian Glaser, Andrea Grüblinger (translated by Marius S.),

The Asus Zephyrus Duo 15 GX550LXS is not your everyday gaming laptop. The keyboard and touchpad are not found in their usual positions; Asus has placed a secondary display with a touchscreen behind them. The octa-core Core-i9-10980HK CPU and a GeForce RTX 2080 Super Max-Q GPU provide enough performance for gaming. There are no direct competitors to the Zephyrus. Thus, we have included slim, lightweight gaming laptops such as the Acer Predator Triton 500 PT515-52, MSI GS66 Stealth 10SFS, and the Gigabyte Aero 15 OLED XB in our comparison.

Case - Asus PC with a Sleek Metal Chassis

The Asus Zephyrus comes in a gray metal case. The Screenpad Plus - a secondary display with a touchscreen - is the main attraction and located above the keyboard. After opening the laptop, the Screenpad raises itself to be angled towards the user. The angle is fixed at 13 degrees and cannot be adjusted. The reasons for elevating the back of the display are not purely ergonomic. Below the Screenpad Plus, there are two airflow vents, through which cool air travels to the inside of the case. The battery is fixed. There is no maintenance hatch.

We have no complaints in terms of the build quality. The clearances are even and we did not notice any sharp edges. The base unit is very rigid and convincingly resists attempts at twisting it. Meanwhile, the lid is not as rigid. However, applying pressure to the back of the lid at least does not create distortions. The hinges hold the lid firmly in position. The display can be opened to a maximum angle of around 120 to 130 degrees. It can also be opened with just one hand.

Compared to its competitors, the Zephyrus weighs more and its dimensions are greater. This of course stems from the Screenpad and its tilt mechanism. The GX550LXS can still be considered a slim and light gaming laptop.

Features - Onboard Thunderbolt 3

The laptop comes with three USB Type-A ports (2x USB 3.2 Gen 1, 1x USB 3.2 Gen 2). The Thunderbolt 3 port (USB Type-C form factor) opens up a wide variety of expandability options (docks, external GPU). Furthermore, it supports Power Delivery 3.0 and DisplayPort via USB-C version 1.4. According to Asus, the DisplayPort supports up to two 4K screens (60 Hz) or one 8K display. An additional monitor can be connected to the HDMI 2.0b port. The laptop does not integrate a card reader.

Communication

The integrated Intel Wi-Fi chip (Wi-Fi 6 AX201) supports the fast ax standard as well as Bluetooth version 5. We recorded excellent transfer rates under optimal conditions (no other Wi-Fi devices in proximity, short distance between the laptop and the server PC). Meanwhile, a Gigabit Ethernet controller from Realteks well-known RTL8168/8111 device family is responsible for wired networking.

Accessories

There is no shortage of accessories. The large box contains a sleeve (ROG Ranger BP2500), a headset (ROG Delta), a mouse (ROG Gladius II Impact gaming mouse), a wrist rest, a second AC adapter (65 watts, USB-C) and a webcam (ROG Eye GC21; 1080p, 60 FPS).

Maintenance

In order to access the internal hardware, the bottom plate needs to be removed. Thankfully, the entire process is fairly easy. After loosening all the screws on the bottom, the bottom plate can be removed. The screw in the bottom right corner should be removed last, since it slightly raises the bottom plate, which makes it easier to remove.

Warranty

Asus offers a two-year warranty for the Zephyrus. For a warranty extension to three years, the manufacturer charges a premium of about 55 Euros (~$64).

Input Devices - The Keyboard of the GX550LXS Comes with RGB Backlighting

Keyboard

Asus has equipped the Zephyrus with a backlit chiclet keyboard. The flat, smooth keys have a short travel distance and a distinct actuation point. The required actuation force is adequate. The keyboard area does not yield while typing. Since there are no palm rests, typing comfortably is impossible. A rubberized wrist rest (width of approximately 6.5 cm or ~2.56 in, angled), which can be placed in front of the laptop, is supposed to alleviate this problem. However, a firm, flat surface is required for this to work. The RGB backlighting can be adjusted according to the user's preferences with the preinstalled Asus Aura software. Asus has delivered a keyboard that is suitable for daily use. That being said, it is not a good choice for regular typing tasks.

Touchpad

The multi-touch-compatible touchpad is located to the right of the keyboard in an upright position. It occupies an area of approximately 5.8 x 7.6 cm (~2.28 x 2.99 in). The space is sufficient for gesture controls. Furthermore, fingers glide effortlessly across the smooth touchpad surface. The two dedicated mouse buttons have a short travel distance and a distinct actuation point.

Asus Screenpad Plus - A Secondary Display for the Zephyrus

The main attraction of the System is the Asus Screenpad Plus - a secondary display with a touchscreen. It supports active pens. The Screenpad (14.1 inches) comes with a matte layer and a native resolution of 3840x1100 pixels. It acts like any other external display. A dedicated key switches it on and off.

In essence, Asus has improved upon Apple's Touchbar concept. This makes it possible to move applications or their control/navigation/input elements to the touchscreen. Support for the latter option depends on the application itself. As an example, chat windows can be moved to the Screenpad while a game runs on the main screen.

Asus has installed a few small applications that provide a look into the potential of the Screenpad. For example, it can be used for displaying a calculator or as a field for handwritten inputs. The Quick Key application displays a few frequently used operations (cut, copy, paste).

Display - Great Colors

The matte 15.6-inch display of the Zephyrus Duo has a native resolution of 3840x2160 pixels. The contrast ratio (1421:1) and brightness (385 cd/m²) are good. Positive: The display does not suffer from PWM flickering. Meanwhile, the response times of the display are nothing to write home about. Here, competing devices tend to achieve better results. However, an alternative configuration with a 300-Hz Full HD display and faster response times is also available.

Both our test device's 60-Hz panel and the aforementioned 300-Hz model support Nvidia G-Sync. It allows the display to dynamically synchronize its refresh rate to the frame rate of the GPU. This is supposed to make the image as smooth as possible - particularly while gaming.

* ... smaller is better

The screen boasts an X-Rite Pantone validation, which guarantees a very natural color representation. With a DeltaE 2000 of 1.6, the display is already within the ideal range (DeltaE of less than three) in terms of color representation. It also does not suffer from a blue tint. We were able to improve the display further by calibrating it. This resulted in a lower color deviation of 0.73 and a more balanced grayscale. The display covers both the AdobeRGB and the sRGB color space.

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
24.4 ms ... rise ↗ and fall ↘ combined↗ 10 ms rise
↘ 14.4 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. » 41 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (24.4 ms).
       Response Time 50% Grey to 80% Grey
56.4 ms ... rise ↗ and fall ↘ combined↗ 26.4 ms rise

The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 636 (maximum) ms. » 92 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (38.7 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: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17531 (minimum: 5 - maximum: 2500000) Hz was measured.

The laptop is equipped with an IPS with great viewing angles. As a result, the display can be read from any position. The outdoor readability of the screen is convincing thanks to its high brightness.

Test Conditions

The preinstalled Armoury Crate control center allows users to choose between different power profiles ("Quiet", "Performance", "Manual", "Windows"). For this review, we selected the "Performance" profile (exception: We used the Windows power profiles for the battery tests). We repeated a few benchmarks using the "Turbo" profile, which the relevant sections will reflect.

Processor

The Zephyrus Duo is powered by an octa-core Core i9-10980HK (Comet Lake) CPU with a TDP of 45 watts. The CPU has a base clock speed of 2.4 GHz. Via Turbo, the clock speeds can be increased to up to 4.4 GHz (on eight cores) or 5.3 GHz (on a single core). Hyper-Threading (two threads per core) is also supported. Lastly, the open multiplier allows for simple CPU overclocking.

During the Cinebench multi-thread benchmark tests, the processor runs at 3.5 GHz to 4.5 GHz (mains) and 2.4 GHz to 4 GHz (battery mode). During the single-thread tests, the clock rates are stable at 4.5 GHz to 4.9 GHz.

In order to determine whether the CPU Turbo is permanently active while on mains, we run the Cinebench R15 multi-thread test in a loop for at least 30 minutes. Here, the scores drop by the third loop and remain fairly consistent for the remainder of the test. Meanwhile, Turbo Boost is active.

With the "Turbo" profile is selected via the Armoury Crate software, the scores are slightly higher.

Storage Solution

Asus has equipped the GX550LXS with two 1-TB NVMe SSDs (M.2 2280) from Samsung. Since they form a RAID 0, the operating system recognizes the two SSDs as one 2-TB SSD. All data stored on the array is distributed across both SSDs. This results in high transfer rates and short loading times - ideal for games.

Two SSDs form a RAID 0

GPU Performance

The GeForce RTX 2080 Super Max-Q graphics card supports DirectX 12 and runs at a base clock speed of 735 MHz. Via boost, it is able to increase its clock speed to up to 1080 MHz. Higher speeds are possible, provided the GPU does not cross certain predefined temperature or energy consumption thresholds. We registered a peak of 1785 MHz. During our "The Witcher 3" test, it runs at an average clock rate of 1330 MHz. The GPU has access to fast GDDR6 video memory (8192 MB).

The 3DMark benchmark results match our expectations for this GPU. The integrated UHD Graphics 630 is active and the laptop uses Nvidia's graphics switching technology Optimus. Optimus - and with it, the iGPU - can be disabled via the Armoury Crate software.

Within the Armoury Crate software, the power profile "Turbo" can be selected to increase the graphics performance. This results in approximately 15% to 20% higher 3DMark benchmark scores.

Gaming Performance

All the latest games run smoothly on the Asus system. For the most part, the FHD resolution and maximum graphics settings can be chosen. Although naturally, the installed GPU is powerful enough to also handle resolutions above Full HD, the quality settings may then have to be dialed back - particularly at 4K.

Selecting the power profile "Turbo" from within the Armoury Crate software results in higher frame rates. The FPS gain depends on the game, resolution and the graphics settings. Specifying a fixed value is not possible. The following comparison table also reflects this.

Emissions - Acceptable Heat and Noise Levels

System Noise

The twin fans permanently run at low speeds during idle. This causes a tolerable amount of noise. Under load, their RPM increases. We registered maximum sound pressure levels of 49 dB(A) (stress test) and 48 dB(A) (The Witcher 3 test). Using a headset is almost mandatory.

Temperature

The processor runs at 2 GHz during our stress test (running Prime95 and FurMark for at least one hour). Meanwhile, the graphics card runs at approximately 1215 MHz. In battery mode, the speeds fluctuate between 800 MHz and 2.4 GHz to 4 GHz (CPU) and 300 MHz to 1500 MHz (GPU). The stress test represents an extreme scenario that does not occur during daily use. We use this test to determine whether the system is stable under maximum load.

We recorded multiple hot spots with temperatures in excess of 50 °C (122 °F) during our stress test and our "The Witcher 3" test. These values are fairly moderate when considering the powerful hardware inside the laptop. That being said, the device is not fit for use on one's lap. Users will not need to worry about the temperatures during day-to-day use.
