* Based on AMD testing as of 10/11/2017. Battery life targets for the AMD Ryzen™ Processor with Radeon™ Graphics assume a 50Wh battery, a fully power-optimized software/hardware solution stack, and the following system configuration: AMD Reference Platform, AMD Ryzen™ 7 2700U, 2x4GB DDR4-2400, graphics driver 17.30.1025, Windows 10 x64 (1703). VP9 battery life improvement of 4.5 hours to 9.2 hours represents 2.04. Actual battery life may vary with system configuration.
