Tablet era (2016–2019) The Samsung Galaxy Book line originated with the release of
Galaxy TabPro S in 2016, a Windows-powered
Intel Core M tablet with a detachable keyboard designed as a competitor to
Microsoft's
Surface Pro. It was the company's first
Galaxy-branded device of any type to run Windows software instead of
Android, replacing the Windows tablets that had been in the
Samsung Ativ line. A year later, the
original Galaxy Book was launched as a detachable tablet available in 10.6-inch and 12-inch configurations with Intel
Kaby Lake processors. In October 2018, Samsung announced the Galaxy Book 2, another detachable tablet that moved to the
ARM-based
Snapdragon 850 processor, offering built-in LTE connectivity and significantly longer battery life at the expense of processing performance compared to Intel-based competitors. In August 2019, the Galaxy Book S was announced in a standard laptop (clamshell) form factor, again using an ARM Snapdragon processor. In its press release, Samsung called the Book S the first release of the new
Galaxy Computing line. The Book S marked a shift for the Galaxy Book brand from detachable tablets to traditional laptop form factors.
Transition to laptops (2019–2021) In October 2019, Samsung announced the Galaxy Book Ion (clamshell) and Galaxy Book Flex (convertible) laptops. Both were
Intel x86 computers and marked the replacement of the
Samsung Notebook 9. They were the world's first laptops with
QLED displays, and the Flex came bundled with an
S Pen stylus. Ahead of
CES 2020, Samsung introduced the Galaxy Book Flex
α (Alpha), a cheaper variant of the Flex. Both the Ion and Flex were released later in 2020. In May 2020, a variant of the Galaxy Book S running on the low-power Intel
Lakefield processor was unveiled, which Samsung described as a "hybrid processor". At the end of 2020, the successors Samsung Galaxy Book Ion2 and Flex2 were announced as part of the 2021 lineup. At Samsung's Unpacked 2021 event in April, several new models were unveiled: the Galaxy Book Odyssey, a gaming laptop (successor to the Notebook Odyssey) with an Nvidia RTX 3050 Ti graphics chip; and a new Galaxy Book (a base-model clamshell laptop sharing its name with the earlier 2017 tablet but now in a traditional laptop form factor), the Galaxy Book Pro, and the Galaxy Book Pro 360 (a convertible, succeeding the Flex). The Galaxy Book Go, featuring a Snapdragon 7c Gen2 processor, was also announced. Throughout 2020 and 2021, these new models cemented Samsung Galaxy Book as a full replacement for the
Samsung Notebook line. In 2021, a foldable Galaxy Book Fold 17 was rumored, although it has not been made official.
Annual refresh series (2022–present) Beginning in 2022, Samsung adopted an annual numbered series for the Galaxy Book line. The Galaxy Book2 series was announced in February 2022, with models including the Book2 Pro 360, Book2 Pro, Book2 360, and Book2 (not to be confused with the similarly named 2018 Galaxy Book 2 tablet). The Galaxy Book3 Ultra, Book3 Pro, Book3 Pro 360, and Book3 360 were unveiled on February 1, 2023. The Book3 Ultra was the first in the line to feature high-end Nvidia GeForce RTX 40 series mobile graphics. The Galaxy Book4 series (Ultra, Pro, Pro 360, and 360) were unveiled on February 26, 2024, featuring Intel's new Core Ultra processors. A base model Book4 followed later. The Book4 Edge, unveiled on May 20, marked a return to ARM-based processors for the line, using the
Snapdragon X Elite. The Galaxy Book5 series (Book5, Book5 Pro, Book5 Pro 360, and Book5 360) were unveiled in September 2024. The Galaxy Book6 series (Book6, Book6 Pro, and Book6 Ultra) were announced at
CES 2026 on January 6, 2026 and released on March 11, 2026. ==Model specifications comparison==
