Radeon RX 6600M vs Radeon RX 6500 XT benchmarks

In our benchmarks, the Radeon RX 6500 XT beats the Radeon RX 6600M in gaming performance.

Our database shows that the Radeon RX 6500 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 6500 XT 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 6600M has significantly more memory with 8 GiB of memory compared to 4 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 slightly lower TDP at 100 W when compared to the Radeon RX 6500 XT at 107 W. TDP (Thermal Design Power) measures total heat output from the chip.

According to the results of the hardwareDB benchmark utility, the Radeon RX 6500 XT is faster than the Radeon RX 6600M.
