GeForce RTX 3090 vs Radeon RX 6800 specs and performance

According to the hardwareDB Benchmark, the GeForce RTX 3090 GPU is faster than the Radeon RX 6800 in gaming.

Our database shows that the Radeon RX 6800 has a slightly higher core clock speed. The core clock speed (or base speed) is the frequency at which the GPU core runs. This metric makes sense when comparing GPUs of a similar architecture or generation. In addition, the Radeon RX 6800 also has a slightly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

Furthermore, the spec sheet for both these GPUs show that the GeForce RTX 3090 has significantly more memory with 24 GiB of memory compared to 16 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the Radeon RX 6800 has a slightly lower TDP at 250 W when compared to the GeForce RTX 3090 at 350 W. Heat output doesn't match power consumption directly but, it's a good estimate.

In terms of raw gaming performance in our GPU benchmark, the GeForce RTX 3090 is better than the Radeon RX 6800.
