Size: will it fit your bag?
Closed, it measures 14.25 × 9.92 in (36.2 × 25.2 cm) and is 0.62–0.82 in thick. A sleeve or laptop compartment needs inner dimensions at least that large; bag makers size compartments by screen class, and chassis in one class differ, so check the numbers, not the label. We list 12 laptops in the 16-inch class: 13.88–14.35 in wide, 9.35–10.86 in deep and 3.58–5.84 lb. By starting weight the ThinkPad P16 Gen 3 is the 10th lightest of 12. Full table: 16-inch laptop dimensions.

Ports: 3 × USB-C, with Thunderbolt 5, 2 × USB-A, HDMI 2.1, Ethernet (2.5GbE), an SD card reader. Charging: USB-C, 180 W.
Graphics power
Graphics options: RTX PRO 1000 Blackwell (power not published); RTX PRO 2000 Blackwell (power not published); RTX PRO 3000 Blackwell (power not published); RTX PRO 4000 Blackwell (power not published); RTX PRO 5000 Blackwell (power not published). The wattage is the maximum graphics power (TGP) the maker states for this chassis; the same GPU runs at different power in different laptops, which changes its speed.
