Display
T450 buyers can choose from three different 14-inch screens that are all based on low-cost TN technology. A WXGA screen with 1366x768 pixels 200 cd/m², 350:1, 112 ppi) marks the start, followed by the WXGA++ model with 1600x900 pixels (250 cd/m², 400:1, 131 ppi) that we are testing. Lenovo also has a touchscreen version of the latter screen, which however not only boosts the price, but also the laptop's weight and thickness. Furthermore, the additional touchscreen layer reduces the screen's brightness (212.5 cd/m²).

Performance
Intel's Core i5-5200U is the successor of the popular Core i5-4200U and Core i5-4210U Haswell models. As well as marginally higher clock rates ranging from 2.2 to 2.7 GHz (2 cores: 2.5 GHz), the dual-core chip also offers approximately 5% higher per-MHz performance thanks to the optimized Broadwell micro-architecture. Despite the new 14 nanometer manufacturing process, the nominal TDP of 15 watts remains unchanged. More information and benchmarks can be found in our CPU database.
