Microsoft unveiled its new Xbox One S console yesterday, and now details are starting to surface about exactly what has changed inside. In an interview with Polygon, The Coalition studio head Rod Fergusson revealed that the new Xbox One S has additional raw GPU and CPU power compared to the original Xbox One console. As Gears of War 4 is a HDR game, The Coalition has been able to take advantage of that extra power to improve frame rates in particularly demanding parts of the game.

Microsoft has confirmed the “additional processing power” in a statement to The Verge. “We have the same SOC architecture as Xbox One today,” explains a Microsoft spokesperson. “For games that want to take advantage of HDR, we gave developers access to a small amount of additional processing power.” The additional processing power won’t be significant, and it appears it’s limited to HDR titles. Microsoft isn’t detailing exactly what chipsets have changed inside the new Xbox One S, but it’s reasonable to assume that the Xbox One AMD APU chip has been downsized somewhat for the smaller console, which will help with processing power and thermal thresholds.
