Radeon RX 6600 vs GeForce GTX 780 comparison

For gaming, the Radeon RX 6600 graphics card is better than the GeForce GTX 780 in our tests.

The Radeon RX 6600 has a significantly 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. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

Next up, in terms of GPU memory, the Radeon RX 6600 has slightly more memory with 8 GiB of memory compared to 6 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 significantly lower TDP at 132 W when compared to the GeForce GTX 780 at 250 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 Radeon RX 6600 over the GeForce GTX 780.
