The Radeon RX 7000 series is a series of graphics processing units developed by AMD, based on their RDNA 3 architecture. It was announced on November 3, 2022[1] and is the successor to the Radeon RX 6000 series. Currently AMD has announced two graphics cards of the 7000 series, RX 7900 XT and RX 7900 XTX.[2] AMD is set to officially launch the RX 7900 XT and RX 7900 XTX on December 13, 2022.[3]

Navi 31
The Navi 31 die features 58 billion transistors, a 165% increase in transistor density than the previous generation Navi 2x. The full Navi 31 die contained 12,288 FP32 cores, equivalent to 6144 Stream Processors.[6] Reportedly, the Navi 31 die has been designed to scale up to 3 GHz frequency, though AMD's Radeon RX 7900 XTX reference design can hit a boost frequency of 2.5 GHz.[7] The Navi 31 die is fabricated on TSMC's N5 process node.
