LG Gram Pro 16Z90U (2026) Review: The Lightest 16-Inch Laptop Gets Serious 2026

The LG Gram Pro 16Z90U (2026) is the lightest 16-inch laptop on the market, and this year it adds serious AI credentials. At just 1,199 grams, it continues LG's tradition of building large-screen laptops that weigh less than many smaller rivals.

But the 2026 model is more than a featherweight. It introduces an OLED panel with adaptive refresh rates and high brightness, plus Intel's latest Core Ultra X7 processor and a dual AI system that works both locally and in the cloud.

Design and Display: Still the Lightest 16-Inch Laptop

LG has long mastered the art of making big laptops that feel impossibly light. The Gram Pro 16Z90U continues that legacy, and the new OLED display makes it easier to work outdoors thanks to higher brightness.

The adaptive refresh rate helps balance performance and battery life, while the OLED panel delivers deep blacks and vibrant colors. For a laptop this light, the screen is a major upgrade.

Performance and AI: Intel Core Ultra X7 358H

Under the hood, the Gram Pro 16Z90U packs Intel's Core Ultra X7 358H processor, based on the Panther Lake architecture. It has 16 cores (4 performance, 8 efficiency, and 4 low-power), speeds up to 4.8 GHz, and 18 MB of Intel Smart Cache.

The integrated Arc B390 GPU handles graphics, while a dedicated NPU delivers up to 50 TOPS for AI tasks. This hardware enables the dual AI system: a local mode that works offline and a cloud mode with GPT-4o and Copilot.

Key Specs at a Glance

• Processor: Intel Core Ultra X7 358H (16 cores, up to 4.8 GHz)
• NPU: Up to 50 TOPS for AI acceleration
• Display: OLED with adaptive refresh and high brightness
• Weight: 1,199 grams
• Ports: 2x USB-A, 2x USB-C (USB4/Thunderbolt 4), HDMI 2.1, headphone jack
• AI: Local offline mode and cloud mode with GPT-4o and Copilot

Connectivity and Ports

The Gram Pro 16Z90U offers a solid selection of ports: two USB-A 3.2 Gen 2x1, two USB-C with USB4 Gen 3x2 (supporting fast charging, DisplayPort, and Thunderbolt 4), one HDMI 2.1, and a 3.5mm headphone/mic jack.

There's also Ethernet support via an RJ45 adapter, though the adapter isn't included. For a thin-and-light laptop, this is a practical port lineup that covers most needs without dongles.

Dual AI Modes: Local and Cloud

The standout feature is the dual AI system. The local mode runs AI tasks offline, which is great for privacy and when you're without internet. The cloud mode taps into GPT-4o and Copilot for more advanced tasks.

This flexibility means you can use AI features wherever you are, without always needing a connection. It's a smart approach that sets the Gram Pro apart from rivals that rely solely on cloud AI.
