AMD Radeon RX 6900 XT Geekbench OpenCL score leaks

We are just a few days before AMD formally launches its fastest Big Navi Radeon graphics card.

AMD flagship Radeon RX 6900 XT spotted

The Radeon RX 6900 XT has been discovered in the Geekbench OpenCL benchmark database. This is the full-fat Navi 21 XTX model featuring 80 Compute Units (5120 Stream Processors). Just like the other two Navi 21-based models, the RX 6900 XT comes with 16GB GDDR6 memory across a 256-bit bus. The card is also equipped with 128MB of Infinity Cache.

The RX 6900 XT features similar frequencies to RX 6800 XT with a boost clock of 2250 MHz. This clock is easily achievable and most partner cards (which are expected) should exceed this frequency. The model also has the same power limit as RX 6800 XT of 300W, which might be interesting for a future apple-to-apple comparison.

With a score of 169779 OpenCL points, the graphics card is 12% faster than RX 6800 XT and 35% faster than RX 6800 non-XT. Interestingly the RX 6900 XT features 11% more Stream Processors than RX 6800 XT and 33% more than RX 6800 non-XT, so the scaling is almost linear, as expected. The graphics card would still lose against NVIDIA Geforce RTX 3080 and RTX 3090 which are respectively 4% and 19% faster than RX 6900 XT.
