Samsung Galaxy Book4 Pro 14" Intel Core Ultra 7 155H 1.4GHz / 32GB RAM / 1TB SSD

Manufacturer: Samsung

The Samsung Galaxy Book4 Pro 14-inch is a productivity-focused laptop built around the Intel Core Ultra 7 155H processor and paired with 32GB of DDR5 RAM and a 1TB NVMe SSD. It features a 14-inch OLED touchscreen running at 2880 x 1800 resolution with a 120Hz refresh rate, anti-reflection coating, and a pixel density of 242.59 ppi, making it a visually detailed panel for day-to-day work.

The CPU operates with a turbo clock speed of 4.8GHz across 22 threads using big.LITTLE architecture, supported by an Intel Arc Xe-LPG 128EU integrated GPU with a turbo frequency of 2250 MHz and DirectX 12 Ultimate support. Connectivity is handled by two Thunderbolt 4 ports and two USB 4 40Gbps ports, alongside a single USB 3.2 Gen 2 Type-A port, HDMI 2.1a output, and Wi-Fi 6E with Bluetooth 5.3. At 1,230 g and 11.6 mm thick, the chassis stays relatively slim, and the feature set includes a fingerprint scanner, 3D facial recognition, Dolby Atmos stereo speakers, a 2MP front camera, and a 3.5 mm audio jack.

Pros
  • The 14-inch OLED/AMOLED touchscreen runs at 120Hz with a resolution of 2880 x 1800 pixels and a pixel density of 242.59 ppi, delivering a sharp and fluid display for a productivity laptop
  • Two Thunderbolt 4 ports and two USB 4 40Gbps ports provide high-bandwidth connectivity for external displays, storage, and docking solutions
  • At 1,230 g and 11.6 mm thick, the chassis is notably slim and lightweight for a 14-inch productivity machine
  • Both fingerprint scanning and 3D facial recognition are available, offering two distinct hardware-based authentication methods
  • The CPU supports big.LITTLE architecture with a turbo frequency of 4.8GHz across 22 threads, supported by 32GB of DDR5 RAM running at up to 7467 MHz
  • Dolby Atmos stereo speakers and a 3.5 mm headset jack are both present, covering wired and built-in audio options
Cons
  • No RJ45 ethernet port means wired network connections require an adapter
  • The integrated Intel Arc Xe-LPG 128EU GPU with 8 execution units is limited in scope for graphics-intensive workloads
  • No DisplayPort output is available, limiting direct display connectivity to HDMI and Thunderbolt-based connections
  • GPS, gyroscope, accelerometer, and compass are all absent, reducing sensor-based functionality compared to more mobile-oriented devices
  • The external memory slot aside, port variety is narrow with only one USB Type-A port and no USB-C ports outside of the Thunderbolt 4 and USB 4 connections
  • Weather sealing is not included, leaving the chassis unprotected against moisture or splashes
Who is this for?

The Samsung Galaxy Book4 Pro 14-inch is well-suited to professionals and mobile workers who need a capable productivity machine that travels light, given its 1,230 g weight and 11.6 mm slim profile. The combination of a 120Hz OLED touchscreen, 32GB of DDR5 RAM, and a 1TB NVMe SSD makes it a practical fit for users handling document-heavy workflows, multitasking across multiple applications, or working with external displays — supported by the ability to drive up to four screens simultaneously via Thunderbolt 4 and USB 4 40Gbps ports. The dual biometric authentication through fingerprint and 3D facial recognition also makes it a sensible choice for security-conscious users in corporate or hybrid work environments.

Who is this NOT for?

Users who require dedicated graphics performance for tasks such as video rendering, 3D modelling, or gaming will find the integrated Intel Arc Xe-LPG 128EU GPU insufficient for those workloads, as its 8 execution units are not suited to sustained graphics-intensive use. The absence of an RJ45 ethernet port makes it a poor fit for environments that rely on wired network connections without additional adapters, and the lack of GPS, gyroscope, and accelerometer rules it out for users who depend on location or motion sensing in their workflow. Those who need a ruggedised or splash-resistant device will also find this machine unsuitable, as no weather sealing is present.
