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.
