Radeon RX 6600 vs GeForce GTX 680 benchmarks

For gaming, the Radeon RX 6600 graphics card is better than the GeForce GTX 680 in our tests.

Our database shows that the Radeon RX 6600 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 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.

Furthermore, the spec sheet for both these GPUs show that the Radeon RX 6600 has significantly more memory with 8 GiB of memory compared to 4 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 680 at 195 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

According to the results of the hardwareDB benchmark utility, the Radeon RX 6600 is faster than the GeForce GTX 680.
