LG Gram Pro (2025) 16Z90TS 16"

Manufacturer: LG

The LG Gram Pro (2025) 16Z90TS is a 16-inch productivity-oriented laptop built around a notably lightweight chassis of just 1238 grams and a slim 12mm profile. It ships with a 2560x1600 IPS display offering a pixel density of 188 ppi, a backlit keyboard, stereo speakers, and a front-facing camera, making it a well-rounded machine for day-to-day professional use. Battery life is rated at 25.5 hours from a 77Wh cell, which is a standout figure for a laptop of this size and class.

Under the hood, the 16Z90TS runs on a processor built on a 3nm process with a turbo clock speed of 5.1GHz, eight threads, and 12MB of L3 cache, paired with 32GB of LPDDR5 RAM running at 8533MHz across two memory channels. Storage is handled by a 2TB NVMe SSD over a PCIe 5 interface. Graphics come from the integrated Arc Graphics 140V with a GPU turbo of 2050MHz and support for up to three external displays. Connectivity includes two Thunderbolt 4 ports doubling as USB 4 40Gbps, two USB 3.2 Gen 1 Type-A ports, one HDMI output, Wi-Fi 7, and Bluetooth 5.4. The system scores 20,093 in PassMark multi-core and 4,333 in the single-core test.

Pros
  • At 1238g and just 12mm thick, the chassis is unusually light and slim for a 16-inch laptop, making it practical to carry through a full workday
  • The 77Wh battery is rated for 25.5 hours of use, meaning most users can go multiple days of moderate work without reaching for a charger
  • Two Thunderbolt 4 ports with USB 4 40Gbps support enable fast data transfer and flexible external display expansion, with the system capable of driving up to three monitors simultaneously
  • DDR5 RAM running at 8533MHz across two channels, paired with a 2TB NVMe PCIe 5 SSD, provides fast memory bandwidth and storage throughput for demanding productivity tasks
  • Wi-Fi 7 support with backward compatibility through older Wi-Fi standards ensures reliable wireless performance on current and future network infrastructure
  • Sleep-and-charge USB ports allow connected devices to be powered even when the laptop is off or in sleep mode
Cons
  • The display lacks an anti-reflection coating, which can make the screen difficult to use in bright or high-glare environments
  • There is no fingerprint scanner or 3D facial recognition, leaving the laptop without biometric authentication options
  • A single microphone and no Dolby Atmos support make the audio setup relatively basic for a productivity-focused 16-inch machine
  • There is no RJ45 ethernet port, so wired network connections require an adapter
  • The integrated Arc Graphics 140V with only 8 execution units does not support ray tracing or DLSS, limiting the laptop to light graphical workloads
  • No external memory card slot is available, which reduces flexibility for users who regularly work with removable storage media
Who is this for?

This laptop is well suited to professionals and knowledge workers who spend long hours away from a desk, thanks to its 25.5-hour rated battery life and a chassis that weighs just 1238g at 12mm thin. The combination of DDR5 RAM, a PCIe 5 NVMe SSD, and Thunderbolt 4 connectivity makes it a capable machine for demanding productivity workloads such as data processing, document-heavy workflows, and multi-application environments. Users who regularly connect to external monitors will also find value here, as the system supports up to three displays simultaneously, and Wi-Fi 7 ensures the wireless connection keeps pace with fast network infrastructure.

Who is this NOT for?

This laptop is not a strong fit for users looking to handle graphics-intensive tasks such as gaming, 3D rendering, or video effects work, as the integrated Arc Graphics 140V with only 8 execution units offers no ray tracing or DLSS support and is not designed for sustained GPU-heavy loads. Those who need wired ethernet connectivity without an adapter will also find the lack of an RJ45 port a consistent inconvenience in office or data-center environments. Similarly, users who rely on biometric login — whether fingerprint or facial recognition — will need to look elsewhere, as neither option is available on this machine.
