GeForce GTX 1660 Ti vs Radeon RX 6900 XT specs and performance

In our benchmarks, the Radeon RX 6900 XT beats the GeForce GTX 1660 Ti in gaming performance.

In our comparison, the Radeon RX 6900 XT has a slightly 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 6900 XT also has a slightly higher boost clock speed. The boost clock speed is the frequency that the GPU core can reach if the temperature is low enough. The allows for higher performance in certain scenarios.

Furthermore, the spec sheet for both these GPUs show that the Radeon RX 6900 XT has significantly more memory with 16 GiB of memory compared to 6 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the GeForce GTX 1660 Ti has a significantly lower TDP at 120 W when compared to the Radeon RX 6900 XT at 300 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 terms of raw gaming performance in our GPU benchmark, the Radeon RX 6900 XT is better than the GeForce GTX 1660 Ti.
