Radeon RX 640 vs GeForce GTX 650 benchmarks

According to the hardwareDB Benchmark, the Radeon RX 640 GPU is faster than the GeForce GTX 650 in gaming.

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.

As stated by the manufacturer, 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 slightly lower TDP at 50 W when compared to the GeForce GTX 650 at 64 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 terms of raw gaming performance in our GPU benchmark, the Radeon RX 640 is better than the GeForce GTX 650.
