GeForce RTX 3090 vs Radeon RX 6600 XT benchmarks

In our benchmarks, the GeForce RTX 3090 beats the Radeon RX 6600 XT in gaming performance.

In our comparison, the Radeon RX 6600 XT has a slightly 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 XT 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.

As stated by the manufacturer, the GeForce RTX 3090 has significantly more memory with 24 GiB of memory compared to 8 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the Radeon RX 6600 XT has a significantly lower TDP at 160 W when compared to the GeForce RTX 3090 at 350 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 3090 over the Radeon RX 6600 XT.
