Scoring 169,779 points in Geekbench OpenCL, the graphics card was 12% faster than the RX 6800 XT, and 35% faster than the RX 6800. Interestingly, the Radeon RX 6900 XT has 11% more stream processors than the RX 6800 XT. and 33% more than the RX 6800, so performance scaling is nearly linear. The RX 6900 XT video card is still inferior to NVIDIA GeForce RTX 3080 and RTX 3090, which are respectively 4% and 19% faster than it in this test.

AMD Radeon RX 6900 XT is a full-fledged model on the Navi 21 XTX chip with 80 compute units (5120 stream processors). Like the other two models based on the Navi 21 chip, the older Radeon RX 6900 XT comes with 16 GB GDDR6 memory and uses a 256-bit bus. And the lack of bandwidth is compensated for by the high-speed Infinity Cache of 128 MB.

The Radeon RX 6900 XT has frequencies similar to the RX 6800 XT, with a base clock of 2015 MHz and a boost clock of 2250 MHz. These figures are easy for the chip, so most partner cards should get better results from factory overclocking. The model has the same power limitation as to the RX 6800 XT – 300W.
