Asus Rog Zephyrus G15 Test

The mechanism for the hinge of the lid of the display is fascinating. When it is opened, it lifts the notebook by just a few millimeters. It’s not a bad idea since this will ensure more airflow. At the very most, not as appealing for people with left hands, would be the arrangement of the ports since they’re on the sides in the front. Users with a mouse in the notebook will not be happy about this.

However, this Zephyrus G15 is well-equipped with ports. While the right-hand side utilizes a MicroSD card reader and a USB 3.2 Gen 2 Type-A port, and on the left side, there are 2 USB 3.2 Gen 2 Type C ports. There’s also a Type-A port, an RJ-45 connector, HDMI 2.0b, and a 3.5mm audio port that can be used for headsets and headphones, as well as the power connector that powers the small power supply. The power supply runs 90Wh of battery which has excellent runtime due to the low-cost components.

The keyboard is based on a unidirectional layout with no numeric keys. However, some unusual elements may not be a hit with all. The keys and shift are incredibly close. The enter key is tiny, and the direction keys are minor. Additionally, some media keys are devoted above the F-keys and various options to perform a second purpose on critical functions. We are particularly impressed by the large touchpad centrally placed with its smooth and nimble surface. It also has enough room on the left and right sides to relax the wrists. We are not a fan of the keyboard’s light source, which makes the font difficult to identify based on the light in the room. The illumination does not work well with the white keys.

To display the screen, ASUS utilizes an IPS matte panel with 2 560 pixels x 1,440 pixels with a three milliseconds reaction timing (gray-to-grey), and the refresh rate is a high of 165 milliseconds. In addition, its color coverage can be set to 100% DCI-P3. It is also certified by Pantone and will be a delight for editors of images. Unfortunately, the brightness and contrast aren’t excellent. The display should not be anything more than 300 nits, and the contrast number of 11,000:1. It’s also lovely its matte screen displays virtually no reflections.

Let’s dive into the workings. Its Zephyrus G15 features an AMD Ryzen 9 5900HS processor with a firm heart. It will be able to keep up with and beat the best Intel processors like the Core i9-1080HK with a TDP of only 35W. It’s an 8-core processor with 16 threads, which can handle the demands of all modern games and apps. Although AMD has somewhat lacked notebook CPUs to date, its Ryzen 5000 series has now eliminated the gap between it and Intel. We anticipate seeing AMD CPUs in notebooks more often in the coming years, at least for price reasons.

Other features inside include 16GB of DDR4-3200 working memory. Upgrading to 32GB is also possible. One TB of nimble M.2 SSD NVMe with PCIe 3.0 is waiting as a drive. A second M.2 slot is available for upgrading. Wireless connectivity is offered through BlueTooth 51 as well as WiFi. If we haven’t talked about it before: the notebook is available for sale at a price of just EUR 2,699 for this configuration and the RTX 3080 model, which we’ll discuss shortly. So we are talking about a notebook that’s aiming towards the premium.

Let’s look at this model, NVIDIA GeForce RTX 3080, which is a graphics card. To do this, we’ll need to go a step further as there are a lot of distinctions from previous generations and desktop-based GPUs. Also, it is worth noting that the MaxQ designation for the mobile GPUs has gone out of fashion too, and the whole affair is now known as GeForce 3000 Mobile RTX.

Okay, let’s get started. The base of the RTX3080 is not like the desktop version GA102 instead of the GA104 version that is also available in the RTX3070. The shaders are reduced significantly. In place of 8704 cores, the mobile version has only 6,144 shaders. The reality further causes confusion: the Mobile 3080 is available in two memory models, which are 8 GB of GDDR6 and 16 GB of GDDR6. Our model has only 8GB, with 256 bits of the interface and 384GB/s. It’s the first impression. So, it’s evident from the first look that performance on the Mobile-3080 won’t surpass that of Desktop GPU.

Do you think that’s all there is to it? Now things are getting interesting at this point. It’s worth noting that the RTX 3080 Mobile is also available in various TDP variations. If we’re not in the wrong place at the moment, there are seven variations, including 80, 90, 115, 130, 125, 145, as well as 150+ Watts which have an impact on the performance of the GPU. Unfortunately, many notebook makers do not yet indicate the TDP version is in use. It was also difficult to determine our test device. Because of its power consumption of a little over 120W, we believe it is the version 115W that the device is present in our particular case. We hope solutions can be discovered quickly to ensure that the labeling is user-friendly and that nobody buys an ox in a poke.

Additionally, we have significant reductions in GPU clock when compared to the desktop version. In addition, the RTX 3080 Mobile runs at 780 MHz or 1,245 MHz in Boost. The final word is that the RTX 3080 Mobile is roughly similar to the RTX 2080S and is by far not within the same range as the desktop beast. Of course, these compromises are perfectly logical in terms of size, cooling, and power consumption.

However, the Zephyrus G15’s layout is very consistent in the whole package. With the display being 1440p with the GPU and CPU, they provide strictly what’s required. Gaming performance is created explicitly for this resolution and allows most games to run at 50-60 fps without making any concessions to the settings. Since specific effects may be reduced due to the high density of pixels at fifteen inches or 1440 pixels, like antialiasing and DLSS (if enabled), as well as frame rate enhancements. The game is generally playable at 60 frames per second with no visible graphic quality restrictions.

This results in a great combination of cooling performance, performance, and the ability to use less power in favor of battery longevity. The same isn’t true for more than one since the cooling system is effective. However, it doesn’t have too much to be improved upon. The temperatures are moderate, below 80 degrees for GPU and 90 degrees for CPU. But the fans have plenty of work to do. At full load, we observed the noise level to be around 55 dB in the space between the display and keyboard and could be heard as an annoying whistling sound.

The temperature of the case is also close to the maximum. It is possible to measure up to 52 ° in the top and middle and about 40 ° in the central area of the key. Naturally, this is due to the small size of the case. Expanding without becoming uncomfortable for the user or more costly is not feasible. It is not possible, at least not impossible, to significantly exceed the dimensions of the small case.

When gaming performance is below 1440p, with each having the highest settings within the relevant gaming benchmarks, there’s not much to complain about at the end, however. Shadow of the Tomb Raider achieved 82 frames per second; the Division 2 barely squeaked past the magic 60 fps mark with 57 fps. The same applies to Borderlands 3 in the Badass setting. F1 nevertheless managed to get the speed of 103 frames per second in the pounding water of China. Massive open-world chunks also dealt with quite well by the notebook in Assassin’s Creed: Valhalla ran blithely at 52 fps. Finally, watch Dogs: Legion at most also surpassed the 50 FPS limit, with 54 frames per second.


However, this brings us to a tricky topic because notebook manufacturers must and should communicate the TDP variant used in each case much more clearly. Otherwise, you might buy a pig in a poke, and instead of the standard power package, you might buy a significantly weaker variant. Moreover, there can be pretty severe differences with (according to our knowledge) seven TDP variants. So pay attention to which TDP variant you get and whether you want the GPU with 8 or 16GB VRAM.

When you purchase the G15 Zephyrus, you’re prepared for modern games and challenging applications. The latest technology and stylish design make a strong case. The only minor flaws include the keyboard’s layout, the case’s somewhat high temperatures in full load, and the fan’s noise; however, it’s still acceptable considering the performance and its smaller dimensions.



  • Compact, slim and light notebook.
  • Pretty design
  • excellent gaming performance with 1440p at 1440p
  • efficient (though not necessarily quiet) cooling

  • low-cost, yet powerful efficient, yet powerful
  • Good display
  • large touchpad that has a nimble and spacious touchpad


  • thunderous fans when at full capacity.
