Radeon RX 6800 vs GeForce RTX 5090 comparison

For gaming, the GeForce RTX 5090 graphics card is better than the Radeon RX 6800 in our tests.

Our database shows that the GeForce RTX 5090 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 GeForce RTX 5090 also has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

Next up, in terms of GPU memory, the GeForce RTX 5090 has significantly more memory with 32 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 significantly lower TDP at 250 W when compared to the GeForce RTX 5090 at 575 W. TDP (Thermal Design Power) measures total heat output from the chip.

In terms of raw gaming performance in our GPU benchmark, the GeForce RTX 5090 is better than the Radeon RX 6800.
