GeForce RTX 3070 Ti vs Radeon RX 5600 XT benchmarks
According to the hardwareDB Benchmark, the GeForce RTX 3070 Ti GPU is faster than the Radeon RX 5600 XT in gaming.
In our comparison, the GeForce RTX 3070 Ti 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 GeForce RTX 3070 Ti also has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.
Furthermore, the spec sheet for both these GPUs show that the GeForce RTX 3070 Ti has slightly more memory with 8 GiB of memory compared to 6 GiB. If you're planning at playing games at high resolutions with high-quality textures, you will need a lot of memory.
In addition, the Radeon RX 5600 XT has a significantly lower TDP at 150 W when compared to the GeForce RTX 3070 Ti at 290 W. Heat output doesn't match power consumption directly but, it's a good estimate.
In conclusion, all specs and GPU benchmarks considered, will recommend the GeForce RTX 3070 Ti over the Radeon RX 5600 XT.
