Radeon RX 6800 XT vs Radeon RX 6650 XT benchmarks

For gaming, the Radeon RX 6800 XT graphics card is better than the Radeon RX 6650 XT in our tests.

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 maximum frequency the chip can reach if power delivery and thermals allow.

Next up, in terms of GPU memory, the Radeon RX 6800 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 6800 XT at 300 W. TDP (Thermal Design Power) measures total heat output from the chip.

According to the results of the hardwareDB benchmark utility, the Radeon RX 6800 XT is faster than the Radeon RX 6650 XT.
