GeForce GTX 1050 vs Radeon RX 640 benchmarks

For gaming, the GeForce GTX 1050 graphics card is better than the Radeon RX 640 in our tests.

The GeForce GTX 1050 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 GTX 1050 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 Radeon RX 640 has significantly more memory with 4 GiB of memory compared to 2 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 1050 at 75 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 GTX 1050 is better than the Radeon RX 640.
