Radeon RX 6600 XT vs GeForce RTX 4070 Laptop benchmarks

According to the hardwareDB Benchmark, the GeForce RTX 4070 Laptop GPU is faster than the Radeon RX 6600 XT in gaming.

Our database shows that the Radeon RX 6600 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 6600 XT 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 GeForce RTX 4070 Laptop has a slightly lower TDP at 115 W when compared to the Radeon RX 6600 XT at 160 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 GeForce RTX 4070 Laptop is better than the Radeon RX 6600 XT.
