Radeon RX 5700 XT vs Radeon RX 6700 XT benchmarks
For gaming, the Radeon RX 6700 XT graphics card is better than the Radeon RX 5700 XT in our tests.
The Radeon RX 6700 XT has a significantly 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 6700 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.
Furthermore, the spec sheet for both these GPUs show that the Radeon RX 6700 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 5700 XT has a slightly lower TDP at 225 W when compared to the Radeon RX 6700 XT at 230 W. Heat output doesn't match power consumption directly but, it's a good estimate.
In terms of raw gaming performance in our GPU benchmark, the Radeon RX 6700 XT is better than the Radeon RX 5700 XT.
