ASUS ROG Zephyrus M16 (GU604, 2023) review – gaming devices can’t really get any better

Temperatures and comfort, Battery Life

Max CPU load

In this test we use 100% on the CPU cores, monitoring their frequencies and chip temperature. The first column shows a computer’s reaction to a short load (2-10 seconds), the second column simulates a serious task (between 15 and 30 seconds), and the third column is a good indicator of how good the laptop is for long loads such as video rendering.

Average P-core frequency; Average E-core frequency; CPU temp.; Package Power

The 5 million heat pipes on this device manage to sufficiently cool the Core i9-13900H, allowing it to keep pretty high clocks in both the P-cores and the E-cores.

Real-life gaming

The same can be said about the graphics performance, which seems to remain undisturbed even after 30 minutes of gaming. However, the relatively low temperature comes at the expense of a lot of noise (in the Turbo mode).

Comfort during full load

Not only that, but the middle part of the keyboard, and the center of the bottom panel get pretty warm with temperatures higher than 50°C.

Battery

Now, we conduct the battery tests with the 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. This device’s 90Wh battery pack lasts for 4 hours and 40 minutes of Web browsing, or 5 hours and 10 minutes of video playback on a single charge.

Video playback

Brightness: 180 nits; Display Mode: SDR
Time to Full Discharge: Higher is Better
