Radeon RX 580 vs Radeon RX 6600 comparison

According to the hardwareDB Benchmark, the Radeon RX 6600 GPU is faster than the Radeon RX 580 in gaming.

Our database shows that the Radeon RX 6600 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 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.

Furthermore, the spec sheet for both these GPUs show that they both have the same amount of memory at 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 slightly lower TDP at 132 W when compared to the Radeon RX 580 at 185 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

In terms of raw gaming performance in our GPU benchmark, the Radeon RX 6600 is better than the Radeon RX 580.
