Radeon RX 640 vs GeForce GTX 750 Ti specs and performance

In our benchmarks, the GeForce GTX 750 Ti beats the Radeon RX 640 in gaming performance.

In our comparison, 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.

As stated by the manufacturer, they both have the same amount of memory at 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 slightly lower TDP at 50 W when compared to the GeForce GTX 750 Ti at 60 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 GTX 750 Ti is faster than the Radeon RX 640.
