Radeon RX 6700 XT vs Radeon RX 6600M specs and performance

For gaming, the Radeon RX 6700 XT graphics card is better than the Radeon RX 6600M in our tests.

The Radeon RX 6700 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 6700 XT also has a slightly higher boost clock speed. The boost clock speed is the frequency that the GPU core can reach if the temperature is low enough. The allows for higher performance in certain scenarios.

Furthermore, the spec sheet for both these GPUs show that the Radeon RX 6700 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 6600M has a significantly lower TDP at 100 W when compared to the Radeon RX 6700 XT at 230 W. Heat output doesn't match power consumption directly but, it's a good estimate.

In conclusion, all specs and GPU benchmarks considered, will recommend the Radeon RX 6700 XT over the Radeon RX 6600M.
