Now in its fourth generation, the super-thin ThinkPad X1 Carbon has proven to be a popular compromise between the more feature-heavy but thicker ThinkPad T460s and a thinner but more barebones Ultrabook. The X1 Carbon is still one of the few Ultrabooks with integrated WWAN, which should appeal to travelers and business users.

We recently published on the higher-end SKU with the Core i7-6500U CPU and WQHD (2560 x 1440) resolution panel. Our latest test unit is one configuration down with a Core i5-6300U CPU and FHD (1920 x 1080) resolution panel. All other factors remain equal save for the slight change in the NVMe Samsung SSD models between our two units. What drawbacks and benefits are there in this less expensive Core i5 FHD SKU compared to the Core i7 WQHD SKU?

We recommend checking out our previous review on the fourth generation ThinkPad X1 Carbon for more pictures and details on the chassis, input devices, and other hardware features.
