Principled Technologies tested 19 games which are Total War: WARHAMMER II, Counter-Strike: Global Offensive, Gears of War 4, War Thunder, Ashes of the Singularity, Forza Motorsport 7, Assassin's Creed: Origins, Far Cry 5, World of Warcraft: Battle for Azeroth, Sid Meier's Civilization VI, Fortnite, World of Tanks, Tom Clancy's Rainbow Six Siege, PlayerUnknown's Battlegrounds, Rise of the Tomb Raider, Middle-earth: Shadow of War, Tom Clancy's Ghost Recon: Wildlands, Grand Theft Auto V and Final Fantasy XV. Now there is no question that the Intel Core i9 9900K will be the fastest CPU for video-games. However, the gap between the AMD Ryzen 7 2700X and Intel's brand new CPU has been noticeably reduced. As we can see, the Intel Core i9 9900K will be around 10-22% faster than the AMD Ryzen 7 2700X in most games. The enormous performance gap in Ashes of the Singularity, Gears of War 4, Forza Horizon 4 and Assassin's Creed Origins has been reduced to more realistic numbers. In other titles, however, the performance gap remained the same. These titles, like Counter-Strike: GO, World of Warcraft and World of Tanks, seem to not be scaling well on multiple CPU cores.
