Microsoft has given GameSpot an official statement, saying the Xbox One S's extra GPU and CPU is not there to improve performance. Instead, it's so developers can make use of the slimmer system's HDR support.

"We have the same SOC architecture as Xbox One today," Microsot said. "For games that want to take advantage of HDR, we gave developers access to a small amount of additional processing power."

HDR stands for high dynamic range. HDR televisions have an expanded color and contrast range, which makes everything brighter and more vibrant. One of the first Xbox One games to support this technology is Gears of War 4, which releases on October 11.

Polygon previously talked to Gears of War 4 head Rod Fergusson, who said the Xbox One S would improve its games' frame rates and resolutions.

The Xbox One S was announced at Microsoft's E3 press conference, and it also supports 4K video. It costs $300 for 500 GB, $350 for 1 TB, and $400 for 2 TB. It releases this August.

A new, more powerful Xbox One dubbed Project Scorpio was also announced. It supports 4K Gaming on more advanced hardware, but Microsoft says all Xbox One games will work on all Xbox One consoles.
