The Lenovo ThinkPad L14 and L15 get processor refreshes and almost 75% longer claimed battery life on the AMD models

Purchasers have a choice between Intel Core 11th Gen or AMD Ryzen 5000 mobile processors on both the 14-inch L14 and larger 15.6-inch L15, with the Intel models identified as L14i and L15i. Display panels range from a 720p TN (avoid) through 1080p IPS and 1080p IPS touch. Meanwhile, the connectivity is dependable for a business notebook with 2 x USB3, USB-C, Thunderbolt 4, HDMI 2.0, RJ45, audio combo jack, and MicroSD.

The Intel model’s graphic output is handled by either Intel Xe or an optional mixed Intel UHD graphics with Nvidia MX450 graphics card for GPU accelerated applications that require dedicated Nvidia hardware. Meanwhile, the AMD models have integrated Radeon GPUs but lack the choice of dedicated graphics.

Fans of robust wireless connectivity won’t need to restrict themselves to one processor option with all models featuring WiFi 6 and optional LTE modules. However, Lenovo believes that those with the AMD models will enjoy that wireless freedom longer with a reported MobileMark 2018 battery life of 14 hours against a sub 8-hour life in the Intel models. The difference isn’t likely to be that large since all models share the same 45 Wh battery capacity. Still, Lenovo must be confident that the AMD model will last longer in business-like workloads similar to MobileMark.
