GeForce RTX 2070 vs Radeon RX 640 specs and performance

For gaming, the GeForce RTX 2070 graphics card is better than the Radeon RX 640 in our tests.

In our comparison, the GeForce RTX 2070 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 2070 also has a slightly higher boost clock speed. The boost clock speed is the frequency that the GPU core can reach if the temperature is low enough. The allows for higher performance in certain scenarios.

Next up, in terms of GPU memory, the GeForce RTX 2070 has significantly more memory with 8 GiB of memory compared to 4 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the Radeon RX 640 has a significantly lower TDP at 50 W when compared to the GeForce RTX 2070 at 175 W. Heat output doesn't match power consumption directly but, it's a good estimate.

According to the results of the hardwareDB benchmark utility, the GeForce RTX 2070 is faster than the Radeon RX 640.
