GeForce RTX 3070 Ti vs Radeon RX 640 specs and performance

According to the hardwareDB Benchmark, the GeForce RTX 3070 Ti GPU is faster than the Radeon RX 640 in gaming.

Our database shows that the GeForce RTX 3070 Ti 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 GeForce RTX 3070 Ti 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 GeForce RTX 3070 Ti 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 640 has a significantly lower TDP at 50 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 terms of raw gaming performance in our GPU benchmark, the GeForce RTX 3070 Ti is better than the Radeon RX 640.
