Radeon RX 6900 XT vs Radeon RX 6650 XT specs and performance

In our benchmarks, the Radeon RX 6900 XT beats the Radeon RX 6650 XT in gaming performance.

Our database shows that the Radeon RX 6650 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 6650 XT also has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

Next up, in terms of GPU memory, the Radeon RX 6900 XT has significantly more memory with 16 GiB of memory compared to 8 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 significantly lower TDP at 176 W when compared to the Radeon RX 6900 XT at 300 W. TDP (Thermal Design Power) measures total heat output from the chip.

In conclusion, all specs and GPU benchmarks considered, will recommend the Radeon RX 6900 XT over the Radeon RX 6650 XT.
