ASUS ROG Strix G15 G512 review – breaches the 4.00 GHz threshold in stress testing

In a world where obnoxious gaming laptops are becoming rarer than undercooked beef, ASUS is actually taking a step back. Now, you can see that the Strix G15 G512 is a gaming device from miles away, with its rather aggressive base and backside. However, the lid cover is pretty sleek, but the glowing strips on the bottom panel are giving it away.

While it falls in the medium-budget part of the market, the laptop offers a wide range of configurations for pretty much everyone. When it comes to the processor, there are two Core i7s – the six-core and the eight-core. When it comes to the GPUs, you can pick from the GTX 1650 Ti if you want to keep the price down, or you can go all the way up to the RTX 2070 Super, should you need to extract the most out of your wallet. Of course, you can get pretty much everything in between these two.

Furthermore, there are two display options, including very fast IPS displays – one 144Hz and one 240Hz.

You can check the prices and configurations in our Specs System:

All ASUS ROG STRIX G15 (G512) configurations


What’s in the box?

The configuration we got comes with a 150W power brick, some paper manuals, and the device, itself. Contrary to the more budget-oriented TUF series, this device’s packaging looks very pretty.

Design and construction

Well, something that definitely keeps the price down is the plastic material. As we mentioned, the design is significant for the ROG Strix series and makes the laptop easily distinguishable. In terms of measurements, this laptop is not one of the most portable ones out there. The weight is 2.39 kg, while the profile stands at 25.9mm tall.

Fortunately, the lid can be opened with a single hand, but its rigidity is not great. Ultimately, this means that the lid is pretty bendy when you force it, and we found that our unit has very fragile side bezels. When we start twisting the lid, the entire side bezel tries to break away and slides off the display. By the way, the ROG Strix G15 G512 lacks a Webcam, similarly to the G531.

When it comes to the keyboard, we see a NumberPad-less unit an RGB backlight, relatively clicky feedback, and good travel. Additionally, there are five multimedia/special buttons above the function key row, which enable you to adjust the sound, turn off the mic, push the fans to the max and enter the ROG app.

One thing we didn’t like about this keyboard is the size of the arrow keys. They are so small, that we don’t see anyone using them for something more than adjusting the brightness or changing the modes of the AURA backlight.

Further down below, you can see the touchpad, which has great gliding and tracking and is extremely comfortable to use. It also has its own dedicated buttons, which have low resistance, and more interestingly – there is a NumberPad function embedded into the touchpad, itself.

Now, looking at the bottom plate we see the ventilation grill, which is not really big in area, but instead – its grills are scattered across a large surface. So, in addition to them, there are the speaker cutouts, which are firing both from the bottom and from the side, and obviously, the huge RGB strip running from the left side to the right, going through the front.


On the left side, there are three USB Type-A 3.1 (Gen. 1) ports and a headphone jack. Then, on the back, you’ll find the power plug, a USB Type-C 3.1 (Gen. 2) port with DisplayPort and G-SYNC support, an HDMI 2.0b connector, and an RJ-45 port.

Disassembly, upgrade options and maintenance

There are 11 Phillips-head screws that hold this notebook’s bottom plate in place. 10 of them can be removed, while one stays attached and lifts the panel upwards, so you can start the prying process from there. By the way, don’t forget the RGB strips, which are connected to the motherboard via two ribbon cables. So, lift gently, then unplug the connectors, and remove the bottom panel from the chassis.

In terms of cooling, there are only two heat pipes, which are shared between the CPU and the GPU. Thankfully, the graphics memory and the VRMs are cooled by thin metal covers. Additionally, unlike some of its biggest competitors out there, the STRIX G15 G512 has only two heat sinks.

How about memory? Well, there are two RAM SODIMM slots, and you can buy the laptop with up to 16GB of DDR4 memory. Probably you will be able to upgrade to 32GB but we can’t confirm that. What is more impressive, however, is that there are three M.2 NVMe slots, and you can configure your storage devices in RAID 0 mode.

Lastly, there is the battery with its 48Wh capacity, which is definitely too small for that hardware, but it’s not something new in the gaming laptop world.

Display quality

ASUS ROG Strix G15 G512 in the configuration we tested has a Full HD 144Hz IPS panel with a model number Panda LM156LF-2F01 (NCP004D). Its diagonal is 15.6″ (39.62 cm), and the resolution 1920 х 1080 pixels. The screen ratio is 16:9, and we are looking at a pixel density of – 142 ppi, and a pitch of 0.18 х 0.18 mm. The screen turns into Retina when viewed at distance equal to or greater than 60cm (24″) (from this distance one’s eye stops differentiating the separate pixels, and it is normal for looking at a laptop).

Viewing angles are excellent. We offer images at 45° to evaluate image quality.

We measured a maximum brightness of 298 nits in the middle of the screen and 274 nits as an average for the whole area, with a maximum deviation of 14%. The Correlated Color Temperature on a white screen is 7460K – colder than the optimal for the sRGB standard of 6500K.
In the illustration below you can see how the display performs from a uniformity perspective. In other words, the leakage of light from the light source.

Values of dE2000 over 4.0 should not occur, and this parameter is one of the first you should check if you intend to use the laptop for color-sensitive work. The contrast ratio is good – 1380:1.

To make sure we are on the same page, we would like to give you a little introduction to the sRGB color gamut and the Adobe RGB. To start, there’s the CIE 1976 Uniform Chromaticity Diagram that represents the visible specter of colors by the human eye, giving you a better perception of the color gamut coverage and the color accuracy.

Inside the black triangle, you will see the standard color gamut (sRGB) that is being used by millions of people in HDTV and on the web. As for the Adobe RGB, this is used in professional cameras, monitors, etc for printing. Basically, colors inside the black triangle are used by everyone and this is the essential part of the color quality and color accuracy of a mainstream notebook.

Still, we’ve included other color spaces like the famous DCI-P3 standard used by movie studios, as well as the digital UHD Rec.2020 standard. Rec.2020, however, is still a thing of the future and it’s difficult for today’s displays to cover that well. We’ve also included the so-called Michael Pointer gamut, or Pointer’s gamut, which represents the colors that naturally occur around us every day.

The yellow dotted line shows ASUS ROG Strix G15 G512’s color gamut coverage.

Its display covers only 55% of the sRGB/ITU-R BT.709 (web/HDTV standard) in CIE1976.

Our “Design and Gaming” profile delivers optimal color temperature (6500K) at 140 cd/m2 luminance and sRGB gamma mode.

We tested the accuracy of the display with 24 commonly used colors like light and dark human skin, blue sky, green grass, orange, etc. You can check out the results at factory condition and also, with the “Design and Gaming” profile.

Below you can compare the scores of ASUS ROG Strix G15 G512 with the default settings (left), and with the “Gaming and Web design” profile (right).

The next figure shows how well the display is able to reproduce really dark parts of an image, which is essential when watching movies or playing games in low ambient light.

The left side of the image represents the display with stock settings, while the right one is with the “Gaming and Web Design” profile activated. On the horizontal axis, you will find the grayscale and on the vertical axis – the luminance of the display. On the two graphs below you can easily check for yourself how your display handles the darkest nuances but keep in mind that this also depends on the settings of your current display, the calibration, the viewing angle, and the surrounding light conditions.

Response time (Gaming capabilities)

We test the reaction time of the pixels with the usual “black-to-white” and “white-to-black” method from 10% to 90% and vice versa.

We recorded Fall Time + Rise Time = 25 ms.

PWM (Screen flickering)

Pulse-width modulation (PWM) is an easy way to control monitor brightness. When you lower the brightness, the light intensity of the backlight is not lowered, but instead turned off and on by the electronics with a frequency indistinguishable to the human eye. In these light impulses, the light/no-light time ratio varies, while brightness remains unchanged, which is harmful to your eyes. You can read more about that in our dedicated article on PWM.

ASUS ROG Strix G15 G512’s display doesn’t flicker at any brightness level. This provides comfort in extended periods of use.

Blue light emissions

Installing our Health-Guard profile not only eliminates PWM but also reduces the harmful Blue Light emissions while keeping the colors of the screen perceptually accurate. If you’re not familiar with the Blue light, the TL;DR version is – emissions that negatively affect your eyes, skin, and your whole body. You can find more information about that in our dedicated article on Blue Light.


ASUS ROG Strix G15 G512 is equipped with the same 144Hz IPS panel, like the TUF A15 (FA506). Similarly, it has comfortable viewing angles, good contrast ratio, and doesn’t flicker under any brightness level. Sadly, though, it covers only 55% of the sRGB color gamut, and a very slow pixel response time, which really takes away from the 144Hz experience.

In addition to receiving efficient and health-friendly profiles, by buying LaptopMedia's products you also support the development of our labs, where we test devices in order to produce the most objective reviews possible.

Office Work

Office Work should be used mostly by users who spend most of the time looking at pieces of text, tables or just surfing. This profile aims to deliver better distinctness and clarity by keeping a flat gamma curve (2.20), native color temperature and perceptually accurate colors.

Design and Gaming

This profile is aimed at designers who work with colors professionally, and for games and movies as well. Design and Gaming takes display panels to their limits, making them as accurate as possible in the sRGB IEC61966-2-1 standard for Web and HDTV, at white point D65.


Health-Guard eliminates the harmful Pulse-Width Modulation (PWM) and reduces the negative Blue Light which affects our eyes and body. Since it’s custom tailored for every panel, it manages to keep the colors perceptually accurate. Health-Guard simulates paper so the pressure on the eyes is greatly reduced.

Now, we conduct the battery tests with Windows Better performance setting turned on, screen brightness adjusted to 120 nits, and all other programs turned off except for the one we are testing the notebook with. Small battery = short battery life. Our 48Wh unit was capable of 5 hours and 18 minutes of Web browsing and 4 hours and 43 minutes of video playback.

In order to simulate real-life conditions, we used our own script for automatic web browsing through over 70 websites.

CPU options

Currently, the notebook can be purchased with either the six-core Core i7-10750H or the eight-core Core i7-10875H.

Results are from the Cinebench 20 CPU test (the higher the score, the better)
