GeForce RTX 3080 vs Radeon RX 6800 specs and performance
For gaming, the GeForce RTX 3080 graphics card is better than the Radeon RX 6800 in our tests.
In our comparison, the Radeon RX 6800 has a slightly higher core clock speed. This is the frequency at which the graphics core is running at. While not necessarily an indicator of overall performance, this metric can be useful when comparing two GPUs based on the same architecture. 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 Radeon RX 6800 has significantly more memory with 16 GiB of memory compared to 10 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 3080 at 320 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 3080 is better than the Radeon RX 6800.
