Radeon RX 640 vs GeForce GTX 670 comparison

For gaming, the GeForce GTX 670 graphics card is better than the Radeon RX 640 in our tests.

The Radeon RX 640 has a slightly higher core clock speed. This is the frequency at which the graphics core is running at. While not necessarily an indicator of overall performance, this metric can be useful when comparing two GPUs based on the same architecture. In addition, the Radeon RX 640 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.

Next up, in terms of GPU memory, they both have the same amount of memory at 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 GTX 670 at 170 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 GTX 670 over the Radeon RX 640.
