ASUS ROG Zephyrus G16 GU605 vs Samsung Galaxy BOOK4 Ultra
Verdict: The ASUS ROG Zephyrus G16 GU605 wins on raw GPU power and display refresh rate, posting 15-20 fps higher averages in 1440p gaming benchmarks from Notebookcheck. The Samsung Galaxy Book4 Ultra trails with its older RTX 4070 and 120Hz panel but offers better stylus integration for note-taking per CNET reviews. Both share similar 32GB RAM configs yet the Zephyrus in sustained performance tests from Tom's Hardware.
Our take: The Zephyrus feels noticeably snappier when switching between Premiere timelines and browser tabs thanks to the newer CPU and faster GPU, while the Galaxy Book4 Ultra's touch display makes casual sketching more natural but the fans ramp up quicker during exports. The Zephyrus hinge feels tighter and the chassis stays cooler on the lap during light browsing.
Winner: ASUS ROG Zephyrus G16 GU605
ASUS ROG Zephyrus G16 GU605: 8.5/10
