New CPUs, GPUs, storage, screens, and more arrive with the fourth-gen X1 Extreme.

Lenovo's ThinkPad X1 Extreme is a business-focused competitor to Dell's XPS 15, bringing a ton of power in a durable, secure chassis. While the ThinkPad X1 Extreme (Gen 3) was mostly a performance refresh over the second generation, the fourth-gen model that I have in for testing goes much deeper with upgrades and refinements. On top of new performance hardware, it has new display options, faster storage, optional 5G connectivity, new speaker layout, and more. I've been using the ThinkPad X1 Extreme (Gen 4) for a couple weeks to see exactly where it excels and whether or not it's worth the fairly chunky price tag.
