Radeon RX 6600 vs Radeon RX 590 GME benchmarks

For gaming, the Radeon RX 6600 graphics card is better than the Radeon RX 590 GME in our tests.

The Radeon RX 6600 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 6600 also has a significantly 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.

In addition, the Radeon RX 6600 has a slightly lower TDP at 132 W when compared to the Radeon RX 590 GME at 175 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 6600 is better than the Radeon RX 590 GME.
