This year has left us in awe as the M16 introduces the AniMe Matrix system, previously exclusive to the G14, making its debut on this model. The question lingers: why the 2023 ROG M16 and not the G15? We do not possess the answer, yet it is undeniable that the ROG Zephyrus M16, formerly known as the M15 series, consistently garners more attention than its counterpart, the Zephyrus G15.

The AniMe Matrix system replaces the M16 2021’s diagonal color lines on the A-side. We find the AniMe Matrix to be more aesthetically pleasing and customizable. As a 2nd generation feature, it boasts an increased number of LEDs, resulting in a brighter display compared to its 1st generation counterpart.

The second area of improvement in the Asus 2023 M16 lies in its cooling system. Employing three fans with high rotational speeds (all exceeding 5500 RPM under heavy loads), and intelligently designed heat sinks that span the device’s main body, ample space is created for optimal heat dissipation. Additionally, the employment of a liquid metal adhesive system, thinner fan blades, and a dust filter for the fans contribute to an effective cooling solution for the M16, which boasts an exceptional configuration.

When it comes to the realm of high-performance laptops with expansive 16″ screens, the Zephyrus M16 stands out for its relatively lightweight build. Surprisingly, it carries a similar weight of approximately 1.6kg compared to both the 16″ MacBook Pro and its own 2021 iteration.

While this generation has foregone the inclusion of a LAN port, the remaining ports are thoughtfully distributed on both sides. Expect to find Thunderbolt 4, HDMI, a 3.5mm jack, as well as a USB-A port.

In all fairness, among all the ROG laptops, the design of the Zephyrus series captivates us the most. It strikes a delicate balance, boasting a slim and lightweight form factor while delivering outstanding performance. As ROG’s premier laptop line, it sets itself apart from the Strix Scar series, which prioritizes performance at the cost of a bulkier, 2kg+ frame. The Zephyrus series, on the other hand, excels in its lighter weight. The Zephyrus M16 follows suit with the G14’s stunning white color variant, a captivating aesthetic. Regrettably, our ROG Zephyrus M16 2023 review unit arrives in Black.


The screen of the Zephyrus M16 undergoes a significant upgrade as it transitions from IPS LCD panels to the remarkable realm of mini LED technology, marking an impressive leap for ROG. The mini LED panel featured in the M16 2023 is undeniably stunning, showcasing vibrant colors and delivering a visually pleasing experience. However, it is important to note that the blooming phenomenon, commonly encountered with mini LED screens, is present.

Regarding color accuracy, popular color ranges such as sRGB, Adobe RGB, and DCI P-3 all exhibit high coverage percentages ranging from 90% to 99%. While ROG boasts a peak brightness of 1100 nits, achieving this level of brightness is rare and limited to specific areas. The overall measured full-frame brightness reaches approximately 600 nits. During nighttime viewing, particularly in dark scenes, a slight halo effect, known as blooming, may become noticeable around subjects—a common occurrence with mini LED screens.

To address this issue, alternative options include utilizing a regular OLED or IPS panel or increasing the number of local dimming zones. While the M16 itself possesses numerous local dimming zones, we don’t have the exact specifics at hand. While the M16 demonstrates notable improvements compared to its 2021 predecessor, it is important to acknowledge that within the realm of laptops equipped with mini LED screens, there are superior options available.

However, there is one aspect in which we firmly believe you will have an exceptional experience with this laptop: playing HDR games and consuming HDR content. With its robust configuration, the M16 undoubtedly handles HDR gaming with ease. Moreover, the screen of the M16 excels in showcasing HDR content, effectively controlling the contrast between light and dark areas better than IPS LCD panels. Windows has long supported HDR, and an array of games and monitors, including the M16, Strix Scar 18, and ROG Flow X16, fully embrace this immersive visual technology.

Keyboard and touchpad

The keyboard and touchpad of the M16 continue to impress, maintaining their exceptional quality. The touchpad boasts a generous size, covered with a smooth glass surface that ensures accurate tracking. Meanwhile, the keyboard delivers a satisfying typing experience, with a sufficient key travel distance and responsive feedback. Though it features a single-zone RGB LED, the M16 offers a plethora of color options, allowing for personalized customization.

Moreover, the keyboard exhibits effective response and seamless performance. As we reflect on the M16’s screen, we still hold a fondness for its remarkably thin bezels. Positioned above the screen is an infrared camera, complemented by a Full HD resolution, enabling convenient face unlock functionality.
