# Samsung Galaxy Book

Samsung Galaxy Book is a line of Microsoft Windows based laptop computers produced by Samsung Electronics of South Korea. The Galaxy Book originated as tablet computers with detachable keyboards, however in 2020 it had evolved into becoming Samsung's main line of laptops, replacing the Samsung Notebook.
The Galaxy Book is a sub-brand of Samsung Galaxy, but unlike those it runs exclusively on Windows software. There is also a separate Galaxy Chromebook line, which is branded under Galaxy Chromebook rather than Galaxy Book.

## History

The Samsung Galaxy Book line originated with the release of Galaxy TabPro S in 2016, a Windows-powered Intel Core M tablet with 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 were in the Samsung Ativ line. A year later the original Galaxy Book was launched, followed another year later by Galaxy Book2 on a Snapdragon 855 ARM-based chip. In August 2019, the Galaxy Book S was announced, in a standard laptop form factor and again using an ARM Snapdragon processor. In its press release, Samsung called the Book S the first release of the new Galaxy Computing line.
In October 2019, Samsung announced the Galaxy Book Ion (clamshell) and Galaxy Book Flex (convertible) laptops. Both of these are 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 is bundled with an S Pen stylus. Throughout 2020 and 2021, further new models were launched that cemented Samsung Galaxy Book as a full replacement brand of the Samsung Notebook line.
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 Galaxy Book S running on low-power Intel Core "Lakefield" was unveiled, which was called a "hybrid processor". At the end of the year, the successors Samsung Galaxy Book Ion2 and Flex2 were announced as part of the 2021 lineup. At Samsung's Unpacked 2021 event the gaming laptop Galaxy Book Odyssey (successor of Notebook Odyssey) with an Nvidia RTX 3050 Ti graphics chip, was unveiled. Galaxy Book Go featured a Snapdragon 7c Gen2 processor.
Samsung Galaxy Book, Book Pro, and Book Pro 360, were unveiled in April 2021. While Book is a base clamshell laptop model, the Pro is a slightly better model, while Pro 360 is a convertible like the Flex was before. In 2021, a foldable Galaxy Book Fold 17 was rumored, although it has not been made official.
The Galaxy Book2 series was announced in February 2022. The models include Book2 Pro 360, Book2 Pro, Book2 360, and Book2.
The Galaxy Book3 Ultra, Book3 Pro, Book3 Pro 360, and Book3 360, were unveiled on February 1st 2023.
The Galaxy Book4 series (Ultra, Book4 Pro, Book4 Pro 360, and Book4 360) were unveiled on February 26th 2024. Later the more base model Book4 was unveiled. This was followed by the Book4 Edge on May 20th, which runs on the ARM-based Snapdragon X Elite processor.
