Radeon RX 6650 XT vs Radeon RX 7900 XTX specs and performance

According to the hardwareDB Benchmark, the Radeon RX 7900 XTX GPU is faster than the Radeon RX 6650 XT 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 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.

Next up, in terms of GPU memory, the Radeon RX 7900 XTX has significantly more memory with 24 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 7900 XTX at 355 W. TDP (Thermal Design Power) measures total heat output from the chip.

According to the results of the hardwareDB benchmark utility, the Radeon RX 7900 XTX is faster than the Radeon RX 6650 XT.
