Review Asus ROG Strix G18 2025 G814 · Ryzen 9 9955HX · RTX 5070
Asus ROG Strix G18 2025 G814 · Ryzen 9 9955HX · RTX 5070
AMD Ryzen 9 9955HX · NVIDIA GeForce RTX 5070 (115W) · 32GB DDR5-5600 (2×16GB) · 1TB SSD (Micron 2500) · 18″ 2560×1600 IPS 240Hz · 2.88 kg
Stable case – very high CPU performance (Zen 5), very good 240Hz display,
decent battery life (~7h), good maintenance options.
Fans almost always active, no Wi-Fi 7, lower brightness than Strix G16,
high price for RTX 5070 laptop GPU.
CPU/GPU combination feels unbalanced – RTX 5070 is the bottleneck.
