GeForce GTX 980 Ti vs Radeon RX 6650 XT specs and performance

In our benchmarks, the Radeon RX 6650 XT beats the GeForce GTX 980 Ti in gaming performance.

The Radeon RX 6650 XT has a significantly 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 6650 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.

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. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the Radeon RX 6650 XT has a slightly lower TDP at 176 W when compared to the GeForce GTX 980 Ti at 250 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 980 Ti.
