15.6" business laptop with Core 5 120U

The Samsung Galaxy Book4 is a 15.6-inch Windows 11 Pro laptop built around an Intel Core 5 120U processor that reaches 5 GHz turbo, 16GB of LPDDR4X memory and a 1TB PCIe NVMe SSD. The IPS display runs at 1920 x 1080 resolution and 60 Hz. Connectivity includes WiFi 6, Bluetooth 5.2 and a wired RJ-45 port.

Buyers who need more than 16GB of memory

The 16GB LPDDR4X is soldered on board and cannot be expanded, so users who run large virtual machines or heavy creative workloads should look at a model with higher capacity or upgradeable RAM. The integrated Iris Xe graphics also limit suitability for modern 3D titles or GPU-accelerated rendering.

Single-channel memory configuration

The specification lists 16GB LPDDR4X without mentioning dual-channel support, which can reduce memory bandwidth compared to dual-channel designs and may affect performance in bandwidth-sensitive tasks.
