Radeon RX 6600 XT vs GeForce GTX 670 specs and performance

In our benchmarks, the Radeon RX 6600 XT beats the GeForce GTX 670 in gaming performance.

Our database shows that the Radeon RX 6600 XT 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 XT also has a significantly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

Furthermore, the spec sheet for both these GPUs show that the Radeon RX 6600 XT 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 XT has a slightly lower TDP at 160 W when compared to the GeForce GTX 670 at 170 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

In conclusion, all specs and GPU benchmarks considered, will recommend the Radeon RX 6600 XT over the GeForce GTX 670.
