Sapphire has confirmed that the Radeon RX 7900 XTX and RX 7900 XT Nitro graphics cards will use cooling systems that use Vapor-X vapor chambers. In addition to the Nitro series, this cooling technology is used in the Sapphire Toxic series and the Vapor-X personalized graphics cards. Vapor-X accelerators have not been approved by the company for a long time.


A short released video also confirms that the Sapphire Radeon RX 7900 XT(X) Nitro graphics cards will get three 8-pin connectors for additional power. They are clearly visible in one of the frames of the video. Also, the video shows for the first time a 3D view of the PCB of the Radeon RX 7900 series with 20-phase VRM power supply.

A quick comparison of Sapphire’s graphics PCB with an image of AMD’s own Radeon RX 7900 reference board shows that Sapphire has made some modifications to the power subsystem, which should bode well for the prospects for additional overclocking.

The official release of the Radeon RX 7900 XTX and RX 7900 XT graphics accelerators will take place on December 13. According to the latest information, non-reference versions of AMD’s new generation graphics cards will be released at the same time as the reference versions.
