Radeon RX 6600 XT vs Radeon RX 6750 XT benchmarks

For gaming, the Radeon RX 6750 XT graphics card is better than the Radeon RX 6600 XT in our tests.

The Radeon RX 6750 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 6750 XT also has a slightly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

Next up, in terms of GPU memory, the Radeon RX 6750 XT has significantly more memory with 12 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 6600 XT has a significantly lower TDP at 160 W when compared to the Radeon RX 6750 XT at 250 W. TDP (Thermal Design Power) measures total heat output from the chip.

According to the results of the hardwareDB benchmark utility, the Radeon RX 6750 XT is faster than the Radeon RX 6600 XT.
