HP released a Ryzen powered laptop recently, the Envy x360, which The Tech Report used to test out the performance of the Ryzen 5 2500U.  The APU sports four cores with a base clock of 2.0GHz, boosting to 3.6GHz and eight GPU CUs with a clock of 1100 MHz.  In order to level the playing field when comparing it to Intel-powered gaming laptops, they installed a Samsung 960 EVO 500GB NVMe which was sadly not installed in the Envy.  The mobile chip's GPU matched a pattern similar to Vega GPUs, offering a bit better performance at lower resolutions but vastly outpacing the performance of Intel's integrated GPU at higher resolutions.  You will still be better off with a mobile GPU playing The Witcher 3 at 1600×900 but the fact that the Ryzen can hit 24fps with decent frame times is very impressive indeed. 

It might even run faster once you remove that certain piece of software recently installed on HP laptops.

"AMD's Ryzen 5 2500U pairs the competitive performance of four Zen CPU cores with eight compute units of Vega graphics power in a notebook-friendly power envelope. We put the Ryzen 5 2500U to the test aboard HP's Envy x360 laptop to see whether the fusion of Zen and Vega results in the best APU yet."
