The Xbox One S console starts shipping in August but according to Microsoft, this smaller version of the original Xbox One console will not make your games run faster. Even though the Xbox One S has a bit more processing power than the original, Xbox planning lead Albert Penello claims there will be no impact on the performance of games as the extra CPU and GPU power is going to HDR support:
"When we made changes to the box for 4K we unlocked a little bit more processing power to enable HDR. That's it. It's exactly the same architecture as the existing one," Penello told me during a presentation on the new console.
"To support HDR, we give people access to a little more CPU and GPU. That's it. It is so insignificant it is mind boggling it is being picked up."
When asked whether there would be any performance difference, Penello was clear:
"I promise, it won't even show up. It will have no impact on games at all. Literally no impact. They will be identical. It's nothing, it is literally nothing."
Even though Microsoft claims there's no difference, the developer of Gears of War 4 claims there is definitely a difference:
Gears of War 4 employs a dynamic resolution system that tweaks the game's rendering resolution in both single-player and multiplayer to maintain its target frame rate in each mode (30 frames per second and 60 fps, respectively). According to Fergusson, the Xbox One S has additional raw GPU and CPU power compared to the Xbox One, and The Coalition's engineers have been able to take advantage of that to reduce the frequency of frame rate or resolution penalties in more demanding sections of the game.
