Radeon RX 590 vs Radeon RX 6600 specs and performance

According to the hardwareDB Benchmark, the Radeon RX 6600 GPU is faster than the Radeon RX 590 in gaming.

In our comparison, 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.

Next up, in terms of GPU memory, they both have the same amount of memory at 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 has a slightly lower TDP at 132 W when compared to the Radeon RX 590 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.
