AMD Radeon RX 6400 Benchmark and Specs

AMD Radeon RX 6400

The Radeon RX 6400 is an AMD GPU that was released in 2022 January. This GPU is average at gaming with a score of 1845 points in our PC benchmark.

The Radeon RX 6400 has 4 GiB of GDDR6 memory, with a total memory bandwidth of 125 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 6400 GPU core runs at a frequency of 1923 MHz and if power and temperature permits, it can boost up to 2321 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 6400 supports up to DirectX 12. In addition, in cross-platform titles, OpenGL 4.6 features are supported. Newer APIs are usually more efficient, allowing for better performance in games and better graphical effects.

This chip has a Thermal Design Power of 53W: the total amount of waste heat generated. A card that runs hotter will need better cooling and will draw more power from the wall.
