In the ROG family (Republic of gamers) from Asus Gaming laptops, the Zephyrus is a particularly compact and relatively light solution. On the other hand, the S model is the one that offers the greatest computing power (processor and graphics chip). Finally, the computer we tested (Zephyrus S GX532GW-AZ120R) is adorned with a color ” Glacier Blue“, More elegant than the traditional black shade which is mostly attributed to machines intended for gamers.

Yes for design and format

The Zephyrus S GX532GW is particularly attractive. The ice blue color of its chassis is of the most beautiful effect. It allows the configuration to be distinguished from the eternal black machines. The chassis, made in magnesium alloy, provides a feeling of robustness and does not retain fingerprints. It also minimizes the weight of the machine. In 15.6 inch format, it measures 36 x 25.2 x 1.89 cm and weighs only 2.05 Kg. However, don’t forget to add the power supply – a good size – which still weighs 796 grams.

One of the main features of the Zephyrux S GX532GW is its AAS system (Active Aerodynamic System), which increases the efficiency of the component cooling system. For this, when you open the laptop by rotating the screen, a part of the chassis, located under the machine, at the back, lifts about 1 cm, to create a space where the air can move more easily.

In practice, if the upper part of the keyboard gets hot
clearly after a game session, we see that the fans are doing well
their job and contain the rise in temperature to a reasonable level:
from 55 to 60 degrees, for the GPU, with peaks at 75 degrees are measured by
the HWiNFO64 application. And the temperature drops quickly as soon as the action
soothes the noise of the fans.

The connectivity of this Zephyrus is complete. Thus, on the right side, there are two USB 3.1 type A and one type C ports, which also acts as a DisplayPort 1.4 connector. The latter also supports technology Power Delivery, which allows you to recharge the battery from a source (external battery, computer, etc.) with a simple USB cable (you can leave the power supply at home). On the left, there is a USB 3.1 type A port, an HDMI connector and the Ethernet, headphone and microphone jacks.

However, we can regret the absence of Webcam and
SD memory card reader.

Yes for
the screen

The Zephyrus S GX532GW is equipped with a 15.6 inch Full HD screen (1,920 x 1,080 pixels). The latter operates a IPS matte LCD panel. In practice, whether for playing, working or reading e-mails, it delivers a very pleasant display, without reflection, which disturbs readability. Its response time is 3 ms.

Besides the AAS system, the other main novelty of this Zephyrus is its 240 Hz maximum refresh rate (against 144 Hz for the previous Zephyrus S, launched a few months ago), which allows you to obtain ever more fluid animations. But is the graphics chip in the configuration suitable for this very high number of images per second? As we will see in the performance section, it depends on the games we like.

In all cases, the G-Sync technology from Nvidia adapts the display frequency to the number of images that the graphics chip can deliver at any one time, in order to ensure a perfectly fluid display, with no tearing effect.

For the rest, the screen is Pantone certified, which guarantees a perfect match between the colors displayed and those defined in professional applications, such as Photoshop.

Yes for the
keyboard and touchpad

The Zephyrus S keyboard incorporates a RGB backlight key by key. It is possible to quickly change the intensity of the backlight (4 levels), using the combination FN + up / down arrow keys. The same key combination, this time the left / right arrows change the effect of the backlight: static, rainbow, pulsation, color cycle, etc.

If the numeric keypad is absent, four keys are highlighted. They are used to change the volume of the speakers, to mute the microphone and to access theArmory Crate of Asus. This application is the nerve center of the laptop, since it contains everything you need to precisely manage performance (of the CPU and GPU), the lighting effects of the keyboard (possibly in coordination with other Asus devices Aura compatible), different networks, etc.

The medium-sized touchpad, with the left keys
and right integrated, can be easily used to browse the web,
manipulate files, etc. The index finger slides well on the surface and
responsiveness is there. However, to play, a mouse remains essential.

Yes – but – for performance

With its processor Intel Core i7-9750H (6 physical cores operating at 2.6 / 4.5 GHz) and 16 GB of DDR4 memory (1333 MHz), expandable to 32 GB, we have a reserve of performance largely sufficient to run the most demanding games.

Especially since the whole is completed by the chip GeForce RTX 2070 from Nvidia. The good performance in Full HD of this is no longer to be demonstrated. The 3Dmark benchmark delivers a maximum score of 7,515, in Turbo mode, 7% higher than the result obtained in “Balanced” mode (6,926).

The PCMark 10 index, which reflects the level of performance for professional use, provides the following (good) results: 4513 (“Balanced” mode with iGP), 4669 (“Turbo” mode with iGP), 6033 ( “Balanced” mode with GPU) and 6164 (“Turbo” mode with GPU).

In the same way, with almost all the games we have used, the RTX 2070 chip generally delivers between 80 and 120 frames per second, with the most sophisticated graphics mode (“Ultra” or “Extreme”). While these results are excellent and are able to satisfy most players, they do not allow you to take advantage of the 240 Hz achievable by the screen.

Game settings
Ashes of the Singularity: Escalation Extreme, GPU test
Tom Clancy’s The Division Ultra
Far Cry 5 Ultra, Blur off
Rise of the Tomb Raider Very High, SMAA, HBAO + off
Civilization VI Ultra / Ultra, MSAA 8x, GPU test
Total War: Warhammer II Ultra, Campaign test

Also, to go beyond the 144 Hz of the previous model, you must either lower the level of graphic details, which is not really the goal of a laptop as sophisticated, or run less demanding games. For example, with games like Fortnite or World Of Tanks, we were able to benefit from a framerate between 144 and 240, without lowering the visual quality too much: “Maximum” settings (the notch just below the highest level) for WoT and in graphic mode “Medium”, even “High”, for Fortnite.

World Of Tanks at 236 fps!

The benchmark integrated into Rise Of The Tomb Raider shows
that with a graphic level “Medium” or “High”, we reach
performance peaks between 220 and 230 images per second.

The interest of the screen at 240 Hz of this Zephyrus is more or
less justified, depending on your preferred type of game.

Another small concern: the noise of ventilation. Because for
to get the best performance, we used “Turbo” mode
in the Asus Armory Crate application, which allows you to adjust the performance level of the CPU, GPU, and which
therefore determines the speed of the fans. However, in this mode, the
noise generated by ventilation becomes very important when the RTX 2070 chip
is in high demand! So much so that it sometimes covers music and
sound effects of certain games (which is a shame because the speakers deliver
quality sound).

So for games with well-paced music, an engine
that roars nonstop or explosions / shots in all directions, the
ventilation noise can be forgotten. But for musical atmospheres
light and mysterious, wearing a helmet is compulsory. This problem does not
is not really one for all those who play with friends and who communicate with
them through a headset with a microphone. We can however take advantage
speakers to watch a movie …

Yes for

Good point, it is possible to exploit the integrated graphic part of the Core i7 (iGP) via the mode Optimus, when you don’t need high performance (web, video, etc.). This allows for greater autonomy. Thus, with the quite demanding BaseMark Web 3.0 test, the battery life of 75 Wh reaches 2 h 35 min, which is an honorable result. By activating the GeForce RTX 2070 chip, the same test only works for 1 h 39 min …

With the PCMark 10 bench, we see a drop in
performance of approximately 25% between the use of iGP and that of GPU.

On the other hand, by watching a 2 h 30 min movie (locally, not in streaming), the battery charge level went from 100% to 25%, despite the use of the “silent” mode (use CPU and GPU). This makes it possible to envisage an autonomy of approximately 3 hours and 20 minutes in video mode.
