Radeon RX 6600 vs GeForce GTX 670 specs and performance

For gaming, the Radeon RX 6600 graphics card is better than the GeForce GTX 670 in our tests.

Our database shows that 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: the maximum frequency the chip can reach if power delivery and thermals allow.

As stated by the manufacturer, the Radeon RX 6600 has significantly more memory with 8 GiB of memory compared to 4 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 6600 has a slightly lower TDP at 132 W when compared to the GeForce GTX 670 at 170 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 Radeon RX 6600 is better than the GeForce GTX 670.
