Radeon RX 640 vs GeForce RTX 3060 Laptop benchmarks

In our benchmarks, the GeForce RTX 3060 Laptop beats the Radeon RX 640 in gaming performance.

Our database shows that 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. Despite this, the GeForce RTX 3060 Laptop 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.

As stated by the manufacturer, the GeForce RTX 3060 Laptop has significantly more memory with 5.97 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 3060 Laptop at 80 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

According to the results of the hardwareDB benchmark utility, the GeForce RTX 3060 Laptop is faster than the Radeon RX 640.
