LG Gram Pro (2025) 17Z90TR 17" specifications and in-depth review

LG Gram Pro (2025) 17Z90TR 17"

Manufacturer: LG

The LG Gram Pro (2025) 17Z90TR is a 17-inch productivity laptop built around a notably lean 1,478 g chassis while still housing a sizeable 90 Wh battery rated for up to 25 hours of runtime. Its 17-inch IPS LCD display renders at 2560 x 1600 pixels with a pixel density of 177 ppi, and the system can drive up to four external displays simultaneously. A backlit keyboard and 3D facial recognition round out the day-to-day usability features, alongside dual microphones and a front-facing camera.

Under the hood, the machine runs on a 5 nm CPU with a turbo clock of 5.1 GHz, 16 threads, and a 24 MB L3 cache paired with 32 GB of DDR5 RAM operating at 8,400 MHz. Graphics are handled by the Arc 140T, a Blackwell-architecture GPU carrying 8 GB of GDDR7 memory across a 128-bit bus, delivering 12.9 TFLOPS of floating-point performance and a texture rate of 201.6 GTexels/s. Storage is a 2 TB NVMe SSD over PCIe 4. On the connectivity side, the laptop offers two Thunderbolt 4 ports, two USB 4 40 Gbps ports, two USB 3.2 Gen 1 Type-A ports, one HDMI output, and Wi-Fi 7 support alongside Bluetooth 5.4.

Pros
  • A 90 Wh battery with a 25-hour rated runtime provides substantial all-day and multi-day endurance for a 17-inch laptop
  • At 1,478 g, the chassis is notably light for its screen size, making it practical to carry regularly
  • Two Thunderbolt 4 ports and two USB 4 40Gbps ports offer high-bandwidth connectivity for external devices and displays
  • Wi-Fi 7 support ensures the laptop is equipped for the latest wireless networking standards
  • The 2,560 x 1,600 IPS display delivers a taller 16:10 aspect ratio resolution with 177 ppi, providing more vertical screen real estate for productivity tasks
  • 3D facial recognition enables hands-free biometric login without requiring a fingerprint scanner
Cons
  • No RJ45 Ethernet port means wired network connections require an adapter
  • The display lacks an anti-reflection coating, which may cause glare issues in brightly lit environments
  • No external memory card slot limits direct file transfer from cameras or other storage media
  • A fingerprint scanner is absent, leaving 3D facial recognition as the only biometric login option
  • The chassis is not weather-sealed or ruggedized, offering no protection against splashes or physical stress
  • No DisplayPort output is available, limiting direct wired display options to a single HDMI port
Who is this for?

This laptop suits professionals and mobile workers who need a large, high-resolution display in a relatively light-weight chassis, particularly those who spend long hours away from a desk and rely on all-day battery endurance. The combination of 32 GB of DDR5 RAM, a 2 TB NVMe SSD, and a 14-core CPU with multithreading makes it well-suited for demanding productivity workloads such as data processing, content creation, and software development. The two Thunderbolt 4 ports and support for up to four external displays also make it a capable hub for users who regularly connect to multi-monitor desktop setups, while Wi-Fi 7 support appeals to those working in environments with modern network infrastructure.

Who is this NOT for?

Users who require a rugged or weather-sealed device for fieldwork or outdoor environments will find this laptop unsuitable, as it carries no such certifications. The single HDMI output, absence of a DisplayPort, and lack of an RJ45 port may frustrate users who depend on wired display and network connections without carrying adapters. Additionally, while the GPU supports ray tracing and DLSS, its 8 GB VRAM and 128-bit memory bus make this machine a poor fit for high-end gaming or GPU-intensive rendering workloads that demand dedicated graphics headroom, and the absence of an anti-reflection coating on the display makes it less practical for use in brightly lit or outdoor settings.
