Asus RoG Zephyrus S GX531GM (i7-8750H, GTX 1060, SSD, FHD) Laptop Review

Unusual. Asus wraps the technology of the Zephyrus S in a thin and compact case. The hardware is able to render every current game smoothly on the matte 144-Hz IPS display. The possibilities to upgrade the device are very limited.
Sascha Mölck, Andrea Grüblinger (translated by Moritz Jordan), 🇩🇪 🇪🇸 ...

The Zephyrus S GX531GM from ASUS was not on our radar. Several weeks ago, we tested the sister model Zephyrus S GX531GS. While both laptops feature the same Core i7-8750H six-core CPU, the GX531GS is equipped with the more powerful GeForce GTX 1070 Max-Q GPU. Today’s review unit has a GeForce GTX 1060. Competitors are the MSI GS65 Stealth Thin 8RE, the Schenker XMG Neo 15, the Razer Blade 15 Base Model, and the HP Omen 15-dc0015ng.

Since both Zephyrus devices are identical apart from the GPU, we will not discuss the case, the accessories, the input devices, the display, and the speakers in this review. Please refer to the review of the Zephyrus S GX531GS for information about them.

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 9700 (minimum: 5 - maximum: 142900) Hz was measured.

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
11 ms ... rise ↗ and fall ↘ combined↗ 6 ms rise
↘ 5 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. » 14 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (24.3 ms).
       Response Time 50% Grey to 80% Grey
7 ms ... rise ↗ and fall ↘ combined↗ 4 ms rise

The screen shows very fast response rates in our tests and should be very well suited for fast-paced gaming.
In comparison, all tested devices range from 0.8 (minimum) to 636 (maximum) ms. » 6 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (38.6 ms).

Performance - The GX531GM does not lack computing performance

With the Zephyrus S, Asus provides a very slim 15.6-inch gaming laptop, which can smoothly render every current game. Our review unit comes at a 2,000 to 2,100 Euro (~ USD 2,300) price point. There are no other trim levels available at the date of our review.

Test conditions

The Zephyrus S has a preinstalled control center software named Armory Crate. The software enables you to set the power management scheme for the laptop. There are five options available: “Silent”, “Balanced”, “Turbo”, “Manual”, and “Windows”. If you choose the last one, the power management of the Windows operating system takes control. We chose this option for our test procedure and performed every benchmark with the Windows power plan “High performance”. Furthermore, we conducted several benchmarks using the “Turbo” option provided by the Armory Crate control center. Please refer to the comparison tables for results.

CPU

The GX531GM features an Intel Core i7-8750H (Coffee Lake) six-core CPU. The mobile processor has a thermal design power (TDP) of 45 W. The base clock speed is 2.2 GHz. The Turbo Boost frequency ranges between 3.9 GHz (six cores) and 4.1 GHz (one/two cores).

During power supply operation, Cinebench multi-thread tests were running with 3.8 to 3.9 GHz for a few seconds (3.6 to 3.9 GHz, if the “Turbo” mode was activated in the control center). After that, the clock speed decreased to 3.1 to 3.2 GHz (3.4 to 3.5 GHz with control center “Turbo”). Single-thread tests were running with 3.9 to 4.1 GHz. During battery operation, a CPU clock speed of 1.9 GHz was held permanently.

HWInfo

Intel XTU

With 30 minutes of continuous multi-thread testing using the Cinebench R15 benchmark, we observed that Turbo Boost was used permanently during power supply operation. However, the results dropped by more than 120 points between the first and the second run but then remained on a constant level.

We also ran the Cinebench R15 loop with activated “Turbo” mode. The results were slightly higher throughout the test because the Turbo Boost of the CPU was operating on a higher frequency.

Storage devices

An NVMe M.2-2280 SSD from Intel as a primary storage device provides 512 GB of storage space, of which 438 GB are free. The difference is occupied by the recovery partition and the Windows installation. The SSD achieves good transfer rates but is not as fast as other NVMe models. NVMe SSDs are connected over PCI Express 3.0 x4, which provides significantly higher transfer rates than SATA III.

Graphics card

GPU-Z
GPU-Z

The GeForce GTX 1060 GPU is Nvidia’s current entry-level model for the top line of GPUs. The GPU supports DirectX 12 and operates with clock speeds of up to 1,671 MHz. The graphics core is accompanied by 6,144 MB of GDDR5 memory. In general, test results were on a typical level for this GPU, but they slightly fell behind the competitors in some cases. This changed when the ”Turbo” mode was activated. However, the performance increase of the GPU turned out noticeably lower than the one of the CPU.

The laptop is able to switch between the CPU-internal and the dedicated GPU. The built-in Intel UHD Graphics 630 was actively used by the system.

Gaming Performance

The Asus gaming laptop is able to render every current game smoothly with Full HD and high to maximum quality settings. Resolutions beyond Full HD are possible only for older games or games that do not have very high hardware requirements - for example “FIFA 19”.

The graphics drivers supplied are unsatisfactory. Current Nvidia drivers cannot be installed. It seems that only driver versions that have been customized by Asus can be used. At the date of the review, the most current driver (version 399.24) on the Asus website was dated September 2018. The game “Battlefield V” refused to start because of the outdated graphics driver.

We were running the game “The Witcher 3” in Full HD and maximum settings for about 60 minutes to check, if the frame rates remain on a constant level for a prolonged time. The in-game character was not moved for the whole time. We did not observe any frame rate drop. With activated “Turbo” mode, frame rates were on the same level.

Emissions & energy - Low endurance

System noise

Compared to the already tested model of the Zephyrus S, our current review unit showed a lower noise emission. We measured a maximum noise level of 34.1 dB(A) under load. This value was slightly exceeded with activated “Turbo” mode. In terms of noise, this laptop stays clearly behind its sister model. The fans generate a constant low-level noise without any disturbing sounds. When idle, the fans usually run at low speed or even remain off sometimes.

Unfortunately, there is a constant coil whine coming from the inside of the device.

Temperature

The GX531GM during the stress test.
The GX531GM during the stress test.

The gaming laptop showed different results during our stress test (Prime95 and FurMark running for at least one hour), depending on whether it was operating on battery or power supply. During power supply operation, the CPU reached a clock speed of 2.1 to 2.5 GHz. The GPU was running at a speed of 1,200 MHz. During battery operation, the CPU was throttled to 800 MHz, while the GPU speed increased to 1,600 to 1,700 MHz.

The temperature increase of the laptop is satisfactory for a device of this size and performance level. We measured temperatures of over 104 °F on several points during our stress test. Thanks to the slower GPU, the GX531GM reached lower temperatures than its sister model.

During day-to-day use, the temperatures stay quite cool. The stress test is an extreme scenario that does not happen during normal use. With this test, we are able to examine, if the system is stable even under full workload.

Power consumption

The power consumption when idle is worthy of improvement. The maximum value of 26 W seems to be somewhat high for a laptop that can switch between integrated and dedicated GPU. Under medium and full load, however, the power consumption remains on a typical level for the built-in hardware components. The power rating of the power supply is 180 W.

Battery life

Our practical-oriented Wi-Fi test simulated the stress during webpage requests. The energy profile “Balanced” was activated, energy-saving functions were deactivated, and display brightness was set to 150 cd/m2. In this test, the Zephyrus S reached a battery life of 3:13 hours. This is not a good value even for a gaming laptop. The competitors are more enduring.

Verdict

The Asus ROG Zephyrus S GX531GM-ES037T, provided by:
The Asus ROG Zephyrus S GX531GM-ES037T, provided by:

The compact gaming laptop from Asus is able to render every current game smoothly on the matte Full-HD display. Furthermore, the six-core CPU provides enough performance for applications beyond gaming. Temperatures and system noise remain on a reasonable level.

The built-in NVMe SSD ensures a snappy system. The matte IPS display offers stable viewing angles, a good contrast ratio, decent brightness, and fast response times. The battery life is not thrilling. The Zephyrus S runs out of power earlier than the competitors.

The upgradability of the laptop is very limited. 

The GC531GM provides only one M.2-2280 slot. There is no space for a 2.5-inch hard drive. Besides that, the laptop has only one memory slot (8 GB of RAM are soldered to the mainboard). The device supports up to 24 GB of memory. Many competitors offer more RAM. To access the internals, you have to open the case. While you can simply remove the bottom case on many other laptops, the procedure on the Zephyrus S is much more cumbersome.

The connectivity is not great as well. Asus does not equip its laptop with a Thunderbolt-3 port but only with two USB Type-C ports (1x USB 3.1 Gen1, 1x USB 3.1 Gen2). A Thunderbolt-3 port should be standard on a device at this price point. This would provide the capability of connecting an external GPU. One of the three Type-A USB ports features the USB 3.1 Gen2 standard. The other two ports are only USB-2.0 capable. Asus should have been consistent and equipped the laptop with three fast Type-A ports. Furthermore, there is a constant coil whine coming from the inside of the device.
