Radeon RX 6800 XT vs Radeon RX 6600M specs and performance

In our benchmarks, the Radeon RX 6800 XT beats the Radeon RX 6600M in gaming performance.

Our database shows that the Radeon RX 6600M 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 6600M also has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

As stated by the manufacturer, 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 6600M has a significantly lower TDP at 100 W when compared to the Radeon RX 6800 XT at 300 W. Heat output doesn't match power consumption directly but, it's a good estimate.

According to the results of the hardwareDB benchmark utility, the Radeon RX 6800 XT is faster than the Radeon RX 6600M.
