Samsung Galaxy Book3 Ultra vs Samsung Galaxy Book4 Ultra

The Verdict

Both laptops share the same 16-inch AMOLED display, 2880x1800 resolution, 120Hz refresh rate, and $2399 price point, but they differ in meaningful ways. The Galaxy Book3 Ultra features Intel's 13th-gen Core i9-13900H with 14 cores and 32GB RAM, delivering superior multi-threaded performance for demanding workloads. The Book4 Ultra counters with Intel's newer Core Ultra 9 185H sporting 16 cores, but only 16GB RAM, which actually throttles real-world performance in memory-intensive tasks. Battery life is the Book4's standout advantage, claiming 13 hours versus the Book3's 8 hours, a significant improvement for mobile users. The Book4 also adds storage expandability, a practical convenience the Book3 lacks. Both weigh nearly 1.86kg (4.1 lbs), have identical port selection with two Thunderbolt connections, and feature Dynamic AMOLED displays. The Book3's superior RAM configuration gives it a performance edge for content creation and multitasking, while the Book4 appeals to road warriors prioritizing battery endurance. For creators and power users, the Book3's 32GB memory is a decisive advantage. For travel-focused professionals, the Book4's 13-hour battery and newer processor architecture justify the choice. This is a genuine tie for most users, though the Book3 edges ahead for performance-intensive work.
