Samsung Galaxy Book4 15.6" Intel Core 7 150U 1.8GHz / 16GB RAM / 512GB SSD

Manufacturer: Samsung

The Samsung Galaxy Book4 15.6-inch is a productivity-oriented laptop that pairs a large screen with a notably slim and light chassis — measuring just 15 mm thick and weighing 1570 g, it sits at the lighter end of the 15-inch category. Built around an Intel Core 7 150U processor with big.LITTLE architecture and a turbo clock of 5.4GHz, it is designed to handle the demands of everyday office and multitasking workloads. Dolby Atmos support adds a layer of audio refinement to the stereo speaker setup, and the inclusion of a fingerprint scanner, backlit keyboard, and front-facing camera rounds out its feature set for day-to-day professional use.

The 15.6-inch LED-backlit display runs at 1920 x 1080 resolution with a pixel density of 141 ppi, an anti-reflection coating, and a 60Hz refresh rate, and the system can drive up to four displays simultaneously. Under the hood, 16GB of DDR4 RAM and a 512GB NVMe PCIe 4 SSD handle storage and memory duties, with the CPU operating across 12 threads with multithreading support. Connectivity is covered by two USB 3.2 Gen 1 Type-C ports, one HDMI output, one RJ45 Ethernet port, an external memory card slot, Wi-Fi 6, and Bluetooth 5.2. Graphics are managed by the integrated Intel Iris Xe Graphics G7 with 96 execution units, supporting OpenCL 3 and OpenGL 4.6, with a GPU turbo frequency of 1300 MHz.

Pros
  • At 1570 g and 15 mm thick, the chassis is notably slim and light for a 15.6-inch laptop, making it more manageable to carry daily
  • The built-in RJ45 Ethernet port provides wired network connectivity without needing an adapter, a practical feature for a productivity device
  • Dolby Atmos support enhances the stereo speaker output for a more structured audio experience during calls or media playback
  • A backlit keyboard, fingerprint scanner, and front-facing camera together cover the core ergonomic and security needs of a work-focused user
  • Wi-Fi 6 support ensures faster and more reliable wireless performance on compatible networks
  • The external memory card slot allows direct file transfers from card-based devices without additional hardware
Cons
  • The 1920 x 1080 resolution on a 15.6-inch panel yields a pixel density of only 141 ppi, which may appear less sharp for text-heavy productivity work
  • There are no USB Type-A ports at all, meaning legacy peripherals and USB-A accessories will require a separate adapter or hub
  • No DisplayPort output is available, limiting options for users with monitors that rely on that connection
  • The absence of USB 3.2 Gen 2, USB 4, or Thunderbolt ports restricts high-bandwidth peripheral and external storage options
  • No brightness specification is listed for the display, and the LED-backlit panel type offers no indication of color accuracy for visual work
Who is this for?

The Samsung Galaxy Book4 15.6-inch is a solid fit for office professionals and remote workers who need a large-screen laptop that remains easy to carry. Its slim 15 mm profile and 1570 g weight make it manageable for daily commutes or travel, while the built-in RJ45 Ethernet port, Wi-Fi 6, and fingerprint scanner address the practical connectivity and security needs of a typical work environment. Users who regularly attend video calls will appreciate the front-facing camera, dual microphones, and Dolby Atmos-enabled stereo speakers, and those who transfer files from memory cards will find the external card slot a convenient built-in option.

Who is this NOT for?

Users who depend on USB Type-A accessories will find the complete absence of USB-A ports a significant inconvenience, as every legacy peripheral will require an adapter. The 16GB DDR4 RAM configuration and integrated Intel Iris Xe graphics make this laptop unsuitable for GPU-intensive work such as video editing, 3D rendering, or gaming, where dedicated graphics and more memory headroom are typically required. Those who prioritize display sharpness for detailed visual work may also find the 141 ppi pixel density on the 15.6-inch panel underwhelming, and users who rely on high-bandwidth docking solutions will be limited by the absence of Thunderbolt or USB 4 ports.
