Why does the Xbox One X have 6 teraflops and the new Xbox Series S only 4 teraflops?
Teraflops have nothing to say in this case.
The Xbox Series S is more powerful than the Xbox One X and that for the reason that newer hardware components are installed. An example would be the SSD that is missing from the Xbox One X. In addition, exclusive technologies come to the fore with the Xbox Series S, these are exclusive to Xbox Series consoles and boost the game by 15%. (VRR, DirectML,.)
