GeForce RTX 2060 vs Radeon RX 640 comparison

In our benchmarks, the GeForce RTX 2060 beats the Radeon RX 640 in gaming performance.

Our database shows that the GeForce RTX 2060 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 GeForce RTX 2060 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 2060 has significantly more memory with 6 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 2060 at 160 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

In conclusion, all specs and GPU benchmarks considered, will recommend the GeForce RTX 2060 over the Radeon RX 640.
