Display

The Zephyrus G16’s 2.5K OLED display leverages pixel-level dimming for deep contrast and covers 100% of both sRGB and DCI-P3 color spaces. This feature contributes to vibrant, color-accurate visuals suitable for gaming, media consumption, and content creation. The 240 Hz refresh rate aids smoothness, though the OLED panel employs PWM (pulse-width modulation) at a high 1 kHz frequency. Users can adjust the ‘OLED Flicker-Free Dimming’ slider in the Armoury Crate app to mitigate flickering effects

Cooling System and Upgrading

The G16 has soldered RAM, limiting upgrade options, though it comes equipped with 32GB LPDDR5x memory. Storage options are more flexible, with two M.2 Gen 4 SSD slots supporting up to 4TB. This model includes a 2TB SK Hynix Platinum P41 NVMe SSD, designed to maintain performance under load. Cooling configurations vary: the RTX 4090 and RTX 4080 models include a vapor chamber, while the RTX 4050, 4060, and 4070 versions utilize a three-fan design. A liquid metal application on the CPU aims to enhance cooling efficiency.

CPU Test

In benchmarks, the Ultra 9 185H performs competitively, scoring 2,446 in Geekbench single-core and 12,016 in multi-core. In Cinebench R23, it achieves 1,809 in single-core and 18,559 in multi-core, showcasing its capability in multi-threaded tasks. In CrossMark, the processor performs well across content creation, productivity, and gaming, holding its own against the i9-13900H, although the latter is slightly ahead in productivity scores.

Rendering and creative work show similar results, with the Ultra 9 185H completing the Blender BMW27 benchmark in 12.5 seconds, just behind the i9-13900H’s 11.8 seconds. Adobe After Effects and Premiere Pro rendering times are also slightly slower but still competitive.

However, the Zephyrus G16’s performance is limited by its 115W TDP, which restricts power allocation compared to similarly priced laptops. Additionally, conflicting settings between Windows’ power management and the ROG Armoury Crate software can lead to occasional performance inconsistencies, impacting the processor’s overall reliability in heavy tasks.

Thermals

It runs warmer than many gaming laptops under heavy use, reaching an average of 39°C (102°F) on the top and peaking at 50°C (123°F), while the bottom can get up to 48°C (118°F)—making it less suited for lap use during intense sessions. However, during lighter tasks or idle, it stays cooler at around 27°C (80°F). Even during gaming, the touchpoints like the palm rests and touchpad remain comfortable at around 32°C (90°F). Overall, the G16’s thermal management is adequate for regular use, though a cooling pad could help manage temperatures during intensive gaming.

Noise

 The G16 stays impressively quiet during light tasks, with fan noise levels between 24 and 30 dB—similar to a quiet room. However, under demanding tasks like gaming, fan noise rises to around 46 dB and can exceed 50 dB at peak, which is noticeable in quieter spaces. For intense usage, headphones could be useful if you’re sensitive to fan noise. Overall, it’s quiet during basic tasks but expect fan noise during heavy workloads

Power Consumption

G16 is energy-efficient for light tasks, drawing minimal power in standby (0.08 to 0.79 Watts) and about 8 to 13 Watts while idling or browsing. However, under heavy loads like gaming or intensive software, it draws significantly more power, ranging from 71 to 169 Watts, which is typical for gaming laptops. Overall, it’s power-efficient for light usage but consumes much more when pushed to full capacity.

Verdict

Decoding the ASUS ROG Zephyrus G16: Power, Design, and Gaming Experience

The Asus Zephyrus G16 is a fantastic gaming laptop with a lot going for it. Right out of the box, the build quality feels premium thanks to the aluminum case, which is sturdy yet compact. The OLED screen with a 240Hz refresh rate and G-Sync is just gorgeous, making everything look super smooth and vibrant. Plus, the speakers sound great, and the keyboard and trackpad are satisfying to use. It’s also nice that it has two SSD slots if you want to add more storage, and overall, the performance doesn’t disappoint.

That said, there are a few things that might give some people pause. The third fan can get a bit annoying when it kicks in, and if you’re looking at configurations below the RTX 4080, you miss out on the Vapor-Chamber cooling, which helps a lot with heat management. Also, RAM is soldered on, so you’re stuck with whatever you get, and some versions only come with 16GB, which could feel limiting down the line. The HDR brightness isn’t as high as you might hope, and there’s no Wi-Fi 7, so it’s not as future-proof as it could be.

Bottom line: The Zephyrus G16 is a solid choice if you want high performance with a stunning display and good audio. But keep in mind the limitations around upgradability, cooling, and connectivity—it’s not perfect, but it’s still a strong contender in its category.
