ThinkPad T16 Gen 4 overview

The Lenovo ThinkPad T16 Gen 4 is a 16.0 inch Copilot+ PC notebook powered by an AMD Ryzen AI 5 PRO 340 processor with integrated AMD Radeon 840M graphics. It ships with 16GB of memory and a 256GB SSD running Windows 11 Pro. The WUXGA display offers a 1920 x 1200 resolution without touchscreen support. Connectivity includes Bluetooth, a webcam, one HDMI port and IEEE 802.11be wireless.

Upgrade considerations

This model replaces older ThinkPad T-series units that lack the Ryzen AI neural processing unit and the newer wireless standard. The jump is worthwhile for professionals who need on-device AI acceleration for productivity features and faster Wi-Fi throughput. Buyers who require discrete graphics performance, larger storage capacities or a touchscreen display should look elsewhere.

Sustained workload behaviour

Integrated AMD Radeon 840M graphics share system memory, so extended heavy compute or media tasks will be limited by the 16GB capacity and thermal envelope of the thin chassis. The processor maintains efficiency for typical office workloads, video conferencing and light content creation over long sessions. Continuous high-intensity rendering or gaming will throttle performance to manage heat.

Questions about this item

What physical dimensions define the 16.0-inch display enclosure?

The chassis is built around a 16.0-inch WUXGA panel with a 1920 x 1200 resolution, so any sleeve or dock must accommodate that footprint.

How is the AMD Ryzen AI 5 PRO 340 processor seated, and what step is often missed?

The CPU is soldered to the mainboard; the step users miss is ensuring the AMD Radeon 840M graphics driver is installed before first boot.

Which component will need replacement first on the 256 GB SSD?

The 256 GB solid-state drive is the only user-replaceable storage module; plan to swap it when capacity or wear becomes an issue.
