Asus ROG Zephyrus S15 GX502L laptop in review: Gaming laptop updated to Comet Lake

It's going to be Super now. Not only does the slim Zephyrus S15 from Asus come with improved hardware in the new edition, but it now also features a 300 Hz panel. In our review, we'll clarify how well this works in combination with the built-in Nvidia GeForce RTX 2070 Super.

Asus ROG Zephyrus S15 GX502L

With the Zephyrus S15 GX502L, Asus is mainly doing a model update. As a result, many features of the Zephyrus S GX502GW predecessor model have been preserved, which is why we will point you to its review article at the appropriate places. Here, we'll focus on the differences that result from the 300 Hz panel as well as the Intel Core i7-10875H and the Nvidia GeForce RTX 2070 Super that have now been installed.

The Zephyrus S15 screen consists of a 15.6-inch IPS panel and offers a resolution of 1920x1080 pixels as well as a refresh rate of 300 Hz. With an average brightness of 289 cd/m², it sits in the middle of our test field. The same applies to the brightness distribution of 90%. In addition, Asus has forgone the use of PWM for brightness control, which is beneficial to users with sensitive eyes.

* ... smaller is better

With a contrast ratio of 1,179:1 and a black level of 0.24 cd/m², the colors on the screen appear well separated from each other, and black image content looks deep and saturated. This is accompanied by a good color-space coverage of 93% (sRGB) and 71% (AdobeRGB), respectively.

The CalMAN analysis also shows that colors are displayed out of the box with a slightly too high blue component and a red component that's too low. These conditions can be almost completely compensated for by calibration. The corresponding ICC file can be downloaded in the window located at the top, to the right of the display's brightness distribution graph.

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
9.6 ms ... rise ↗ and fall ↘ combined↗ 5.2 ms rise
↘ 4.4 ms fall
The screen shows fast response rates in our tests and should be suited for gaming.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 10 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (24.4 ms).
       Response Time 50% Grey to 80% Grey
14 ms ... rise ↗ and fall ↘ combined↗ 6.8 ms rise
↘ 7.2 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 636 (maximum) ms. » 11 % of all devices are better.
This means that the measured response time is better 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 9600 (minimum: 5 - maximum: 142900) Hz was measured.

The Asus gaming laptop's IPS panel is very viewing-angle stable. Image content can be read from almost any angle without becoming distorted or displaying the wrong colors.

Performance - Gaming laptop for demanding games

With the Zephyrus S15, Asus is aiming at gamers who want to run modern titles at high graphics levels and are looking for a device that is as slim as possible. Asus's gaming laptop meets these demands with the hardware installed here, but the ROG Zephyrus S GX502GW predecessor model is still able to do so as well.

Processor

With its eight cores and clock rates between 2.3 and 5.1 GHz, the Intel Core i7-10875H used here offers about 10% more performance compared to the Intel Core i7-9750H found in the ROG Zephyrus S GX502GW. In comparison with the rest of the test field, the CPU installed here achieves a slightly above-average result.

In our Cinebench R15 endurance test, the Core i7-10875H can maintain its performance even over a longer period of time. Therefore, users don't have to expect a drop in CPU performance even under heavy load.

Our The Witcher 3 continuous load test was performed at "Ultra" graphics settings, and it showed that the actually very high frame rates of about 80 fps are occasionally marked by significant drops that can lead to disturbances in gameplay.

Emissions - Good speakers and occasional coil whine

Noise emissions

The Asus ROG Zephyrus S15's fans can be very bothersome under load at a noise level of up to 57 dB(A). However, since most games also deliver smooth frame rates in the "Quiet" performance profile, the noise level can be significantly reduced in everyday use.

When accessing files, a clear coil whine can be heard.

Temperature

The surfaces of the Zephyrus S15 heat up to 51 °C (~124 °F) in our test. Because this temperature occurs primarily in the rear area of the top side, the gaming laptop from Asus can still be used without any problems on the lap, for example.

During our stress test, which lasted about an hour, the internal temperatures rose up to 94 °C (~201 °F), and the clock rates dropped to an average value of about 2 GHz, which is below the base clock speed of the i7-10875H. In our The Witcher 3 endurance test, however, the clock rates could be maintained at an average of 3.9 GHz while temperatures remained moderate; therefore, players don't have to fear any performance drops due to excessive temperatures in everyday use.

Speakers

The speakers in the Zephyrus S15 offer high volume and a broad sound spectrum. This allows for the consumption of both games and media content without the absolute need for external speakers or headphones.

Energy management - Short battery life

Energy consumption

With a consumption of up to 232 watts under load, the Asus ROG Zephyrus S15 shows a comparatively high energy consumption. However, the included 240-watt power adapter has sufficient capacity to provide it with the necessary energy.

A 65-watt power adapter is also included in the box, which has enough capacity to supply the device with energy over USB Type-C in office usage.

Battery life

The Zephyrus S15 from Asus achieves a runtime of about three hours in our practical WLAN test. Consequently, it has shorter battery life than the predecessor model with the same battery capacity. It's also the gaming laptop with the shortest battery life in our test field.

Pros

+ good gaming performance
+ very good speakers
+ slim case

Cons

- fans can become very loud
- no memory card reader

Verdict - Shorter battery life with a "Super" GPU

In review: Asus ROG Zephyrus S15 GX502L. Test device provided by: Asus Germany

The Asus ROG Zephyrus S15 GX502L is, without a doubt, a powerful gaming laptop. The slim design also makes it a quite mobile device if you're willing to regularly look for an outlet for the smaller of the two power adapters. In gaming mode, the ventilation system ensures good frame rates, even without the fans having to be turned all the way up.

With the Asus ROG Zephyrus S15, modern games can be played at maximum details without any issues.

But this raises the question for prospective buyers of why they should choose this model. The predecessor device is available for a similar price, offers a comparable gaming performance, and lasts a bit longer on battery power. The increase in performance is not too big despite the more current CPU and the inclusion of the RTX 2070 Super instead of "only" the RTX 2070. But if you value maximum performance over battery life, you will be very satisfied with the Zephyrus S15.

Editor of the original article: Mike Wobker - Editor
I made my first IT walking attempts on a 386 with 4 MB of RAM. After that followed various PCs and notebooks, which I looked after and repaired in my circle of friends and acquaintances. After an apprenticeship as a telecommunications systems engineer and several years of professional experience, I graduated with a bachelor's degree in industrial engineering. Today I live out my fascination for IT, technology and mobile devices by writing test reports. In my free time I like to devote myself to vegan cooking and spend time with my family, which includes a whole range of animal roommates.
