Samsung Galaxy Book4 Ultra 16" Intel Core Ultra 9 185H 2.3GHz / Nvidia GeForce RTX 4070 Laptop / 32GB RAM / 2TB SSD

Manufacturer: Samsung

The Samsung Galaxy Book4 Ultra 16″ is a productivity laptop built around Intel's Core Ultra 9 185H processor and an Nvidia GeForce RTX 4070 Laptop GPU, targeting users who need a capable machine for demanding workloads and creative tasks. It features a 16-inch OLED touch display running at 2880 x 1800 pixels with a 120Hz refresh rate, 500 nits of brightness, and an anti-reflection coating — a combination that makes for a sharp, fluid viewing experience across different lighting conditions. The chassis measures 16.5 mm thin and weighs 1,860 g, with a backlit keyboard and biometric security covered through both a fingerprint scanner and 3D facial recognition.

Under the hood, the Samsung Galaxy Book4 Ultra pairs its 22-thread CPU with 32GB of DDR5 RAM running at 7,550 MHz and a 2TB NVMe SSD for storage, with memory expandable up to 96GB. The RTX 4070 Laptop GPU brings 8GB of GDDR6X VRAM, 20.04 TFLOPS of floating-point performance, DLSS support, and ray tracing capability. Connectivity is broad, including two Thunderbolt 4 ports, two USB 4 40Gbps ports, one USB 3.2 Gen 2 Type-C, one USB 3.2 Gen 2 Type-A, HDMI 2.1a, Wi-Fi 6E, and Bluetooth 5.3. The 76 Wh battery is rated for up to 11 hours of use, and the system supports Dolby Atmos audio through its stereo speakers.

Pros
  • The 16-inch OLED touch display with a 120Hz refresh rate, 2880x1800 resolution, and anti-reflection coating delivers sharp, fluid visuals suited to both content work and everyday use
  • DLSS and ray tracing support extend the laptop's capability for graphically demanding tasks alongside its dedicated RTX 4070 Laptop GPU
  • Two Thunderbolt 4 ports with USB 4 40Gbps speeds provide fast data transfer and flexible external display or device connectivity
  • 3D facial recognition combined with a fingerprint scanner offers two distinct biometric security options without requiring additional hardware
  • Dolby Atmos support through the built-in stereo speakers adds a meaningful audio dimension for media consumption
  • The 76 Wh battery is rated for 11 hours of use, and sleep-and-charge USB ports allow connected devices to be powered even when the laptop is in sleep mode
Cons
  • At 1,860 g, the laptop is on the heavier side for a 16-inch productivity machine, which may be a consideration for users who carry it frequently
  • The warranty period is limited to one year, which is relatively short for a high-specification laptop
  • No RJ45 port is available, so wired Ethernet requires an adapter
  • The system is not weather-sealed, offering no protection against splashes or moisture exposure
  • A stylus is not included despite the presence of a touch screen, limiting stylus-based input without additional purchase
  • There is no DisplayPort output, and video connectivity is limited to a single HDMI 2.1a port for wired display connections
Who is this for?

The Samsung Galaxy Book4 Ultra is well-suited for creative professionals and power users who need a capable machine for content creation, rendering, and GPU-accelerated workflows, thanks to its RTX 4070 Laptop GPU with DLSS and ray tracing support and 32GB of DDR5 RAM expandable up to 96GB. The 16-inch 120Hz OLED touch display with high pixel density and Dolby Atmos audio makes it a strong fit for users who work with visual media and value display accuracy and immersive sound. Those who rely on fast external device connectivity will also benefit from the two Thunderbolt 4 ports and Wi-Fi 6E support, making it a practical choice for studio or hybrid work environments.

Who is this NOT for?

Users who prioritize portability above all else may find the 1,860 g weight a limiting factor when carrying the laptop across multiple locations throughout the day. Those who need wired network connectivity for reliability or security will be inconvenienced by the absence of an RJ45 port, requiring an adapter for Ethernet access. The laptop is also not suited for users who work in environments where moisture or dust exposure is a concern, as it carries no weather-sealing, and the single HDMI output with no DisplayPort may restrict users who need to connect multiple external monitors through native wired video outputs alone.
