Description
High-Capacity RDNA 3 Graphics
The SAPPHIRE Radeon RX 7900 XT pairs AMD’s RDNA 3 architecture with a substantial 20GB GDDR6 frame buffer. Its 84 Compute Units and 5376 stream processors are supported by a 320-bit memory interface and 80MB of Infinity Cache. This combination gives the card the memory capacity and graphics resources expected from a high-end RX 7900-series GPU.
Reference-Design Connectivity
The reference-format RX 7900 XT supports DisplayPort 2.1, HDMI 2.1 and USB Type-C connectivity, along with resolutions up to 8K. Its compact-for-class 276 mm length and 2.5-slot format distinguish it from many larger custom RX 7900 XT designs.
