Radeon RX 6600 XT vs Radeon RX 7700 XT comparison

In our benchmarks, the Radeon RX 7700 XT beats the Radeon RX 6600 XT in gaming performance.

Our database shows that the Radeon RX 6600 XT 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 6600 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 7700 XT has significantly more memory with 12 GiB of memory compared to 8 GiB. If you're planning at playing games at high resolutions with high-quality textures, you will need a lot of memory.

In addition, the Radeon RX 6600 XT has a significantly lower TDP at 160 W when compared to the Radeon RX 7700 XT at 245 W. TDP (Thermal Design Power) measures total heat output from the chip.

According to the results of the hardwareDB benchmark utility, the Radeon RX 7700 XT is faster than the Radeon RX 6600 XT.
