Radeon RX 6600 vs Radeon RX 6750 XT specs and performance

In our benchmarks, the Radeon RX 6750 XT beats the Radeon RX 6600 in gaming performance.

Our database shows that the Radeon RX 6750 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 6750 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.

Furthermore, the spec sheet for both these GPUs show that the Radeon RX 6750 XT has significantly more memory with 12 GiB of memory compared to 8 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the Radeon RX 6600 has a significantly lower TDP at 132 W when compared to the Radeon RX 6750 XT at 250 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 6750 XT is better than the Radeon RX 6600.
