GeForce GTX 1660 SUPER vs Radeon RX 6950 XT benchmarks

In our benchmarks, the Radeon RX 6950 XT beats the GeForce GTX 1660 SUPER in gaming performance.

Our database shows that the Radeon RX 6950 XT 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 6950 XT 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.

Next up, in terms of GPU memory, the Radeon RX 6950 XT has significantly more memory with 16 GiB of memory compared to 6 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the GeForce GTX 1660 SUPER has a significantly lower TDP at 125 W when compared to the Radeon RX 6950 XT at 335 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 Radeon RX 6950 XT is better than the GeForce GTX 1660 SUPER.
