AMD Radeon RX 640

The Radeon RX 640 is an AMD GPU. This GPU is bad at gaming with a score of 6% in our PC benchmark.

The Radeon RX 640 has 4 GiB of GDDR5 memory, with a total memory bandwidth of 54 GB/s. The memory bus has a width of 64 bits. If you plan on gaming at higher resolutions with higher quality textures, more memory is important. Without enough memory, performance will be degraded.

In terms of clock speed, the Radeon RX 640 GPU core runs at a frequency of 1082 MHz and if power and temperature permits, it can boost up to 1287 MHz. The clock runs at a speed called the clock speed. It dictates the number of updates per second that the GPU can process. Overclocking a chip, which means increasing the clock speed will improve the performance. However, thermals and power efficiency may be diminished.

As for rendering API support, the Radeon RX 640 supports up to DirectX 12. In addition, in cross-platform titles, OpenGL 4.6 features are supported. If your GPU is too old and doesn't support a newer API certain titles may not be playable.

The AMD Radeon RX 640 has a TDP of 50W, this is the amount of heat energy produced by the chip as a byproduct. The higher the TDP, the more heat is produced.
