The new Radeon RX 6900 XT is here with the same 26.8 billion transistors, but it packs 80 Compute Units (CUs) and 80 Ray Accelerators (versus the 72 and 60 for each inside of the Radeon RX 6800 XT, and Radeon RX 6800, respectively). This results in 5120 stream processors (up from the 4608 inside of the RX 6800 XT and 3840 inside of the RX 6800).
GPU clocks aren’t any higher for the reference Radeon RX 6900 XT as they are to the Radeon RX 6800 XT reference, with Game GPU clocks of up to 2015MHz and boost GPU clocks of up to 2250MHz. The additional Compute Units provide more performance across the board, leading to 23.04 TFLOPs of single precision performance, versus 20.74 TFLOPs on the Radeon RX 6800 XT.
