GeForce RTX 3080 vs Radeon RX 6600M benchmarks

According to the hardwareDB Benchmark, the GeForce RTX 3080 GPU is faster than the Radeon RX 6600M in gaming.

Our database shows that the Radeon RX 6600M has a significantly 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 6600M 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.

As stated by the manufacturer, the GeForce RTX 3080 has slightly more memory with 10 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 GeForce RTX 3080 at 320 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 GeForce RTX 3080 over the Radeon RX 6600M.
