GeForce RTX 3070 vs Radeon RX 640 comparison

For gaming, the GeForce RTX 3070 graphics card is better than the Radeon RX 640 in our tests.

Our database shows that the GeForce RTX 3070 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 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 GeForce RTX 3070 has significantly more memory with 8 GiB of memory compared to 4 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 640 has a significantly lower TDP at 50 W when compared to the GeForce RTX 3070 at 220 W. TDP (Thermal Design Power) measures total heat output from the chip.

In conclusion, all specs and GPU benchmarks considered, will recommend the GeForce RTX 3070 over the Radeon RX 640.
