Expert Analysis

Specs web-verified from manufacturer datasheets · Servnet-reviewed · Last reviewed 26 Jul 2026

The Lenovo ThinkPad T14 Gen 6 edges ahead with Copilot+ PC compliance on its Lunar Lake and AMD builds, a quicker NPU for AI tasks, and a 57 Wh battery option, delivering longer runtime. It also boasts a slightly slimmer profile. Under the hood, the Gen 6 offers Intel Core Ultra (Series 2) or AMD Ryzen AI PRO options with NPUs of up to 48 TOPS (Lunar Lake) or 50 TOPS (AMD), while the Gen 5's stocked Core Ultra 5 135U has an 11-TOPS NPU. Battery capacity also rises from 52.5 Wh to up to 57 Wh, with rapid charging on both. However, the Gen 5 holds its ground with fully socketed DDR5 memory across all configurations, allowing cost-effective upgrades to 64 GB—whereas on the Gen 6 only the Arrow Lake and AMD builds are socketed and the Intel Lunar Lake builds solder their memory. Both stocked builds use a 400-nit 14-inch WUXGA panel, and both machines share Thunderbolt 4 connectivity and MIL-STD-810H durability. For UK businesses ready to embrace AI-enhanced Windows experiences, the Gen 6 is the clear pick. Organisations with existing RAM upgrade strategies or tighter budgets may still find the Gen 5 a capable and flexible workhorse.
