Review MSI Katana A17 AI B8VG
MSI Katana A17 AI B8VG · Ryzen 7 8845HS · RTX 4070
AMD Ryzen 7 8845HS · NVIDIA GeForce RTX 4070 Laptop (105W) · 32GB DDR5-5600 (2×16GB) · 1TB SSD (Samsung PM9C1) · 17.3″ 1920×1080 IPS 144Hz · 2.691 kg
Better performance-per-watt – great graphics performance for the price,
no CPU or GPU throttling issues, good cooling performance,
relatively easy to service.
No G-Sync or Advanced Optimus, fingerprint-loving plastic chassis,
low quality 1080p panel, short battery life.
Great for gaming if you avoid the cheaper display option – QHD upgrade is expensive.
