The Tech Report tested the gaming prowess of the new Ryzen 2 chips in a variety of games at 1080p; as the 1080 Ti they used in all the test systems equalled the playing field so that the CPU performance could been seen.  If you game at higher resolutions, then the performance delta is moot as it is your GPU which is handling the load but at 1080p gaming, CPU and DDR frequency matters.  While the new chips did not manage to surpass Intel's they closed the gap noticeably compared to the initial generation of Ryzens and they were capable of doing something Intel's offerings simply can't.  Those who like to stream their games while they play would do well to consider the Ryzen 7 2700X and Ryzen 7 1800X as they offered a significantly better experience and were the only ones capable of a decent stream of the latest Deus Ex game.
