GeForce GTX 1660 vs Radeon RX 6650 XT benchmarks

According to the hardwareDB Benchmark, the Radeon RX 6650 XT GPU is faster than the GeForce GTX 1660 in gaming.

Our database shows that the Radeon RX 6650 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 6650 XT also has a significantly 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 6650 XT has slightly more memory with 8 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 has a significantly lower TDP at 120 W when compared to the Radeon RX 6650 XT at 176 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 6650 XT over the GeForce GTX 1660.
