Samsung Galaxy Book4 Ultra vs Samsung Galaxy Book5 Pro

The Verdict

Both machines share the same 16-inch 2880x1800 Dynamic AMOLED 2X display and 76 Wh battery, but they diverge sharply in priorities. The Book4 Ultra packs an Intel Core Ultra 9 185H with 16 cores and pairs it with discrete GPU capability, making it a legitimate workstation replacement for video editors and 3D artists. The Book5 Pro uses the newer Intel Core Ultra 7 265V, an efficiency-focused chip with only 8 cores, but that architecture pays dividends: Samsung claims up to 18 hours of battery life versus 13 hours on the Ultra, and the Book5 Pro is notably lighter at 1.56 kg compared to 1.86 kg. The Book5 Pro also edges out on display brightness at 500 nits versus 400 nits. Storage is a concern on the Book5 Pro, which ships with only 512 GB and no expandable storage slot, while the Book4 Ultra gives you 1 TB and an SD card slot. At $2,399 versus $1,449, the $950 premium for the Ultra is hard to justify unless you genuinely need sustained multi-threaded performance or discrete graphics. For most professionals who prioritize portability, battery endurance, and everyday productivity, the Book5 Pro delivers more practical value per dollar.
