AMD Radeon R9 M390X

The Radeon R9 M390X is a GPU from AMD released in 2015. This chip has an average gaming score at 24% in our GPU benchmark.

The Radeon R9 M390X has 4 GiB of GDDR5 memory, with a total memory bandwidth of 156 GB/s. The memory bus has a width of 256 bits. More memory is beneficial when gaming at high resolutions as the memory needs to store the frame buffer and all the game textures. If you run out of memory, you will experience poor performance as the GPU needs to swap data in and out of the memory as it is used.

In terms of clock speed, the Radeon R9 M390X GPU core runs at a frequency of 723 MHz. The core clock is directly related to the performance of a GPU, the higher the clock, the more processing can be done per second. A higher clock does not guarantee better performance by itself, this also depends on the number of shading units and other elements of the pipeline.

The performance specs of the Radeon R9 M390X are a raw floating-point performance of 2.96 TFLOPS : this represents the number of floating point (decimal) operations completed per second. In addition, this AMD GPU has a pixel rate of 23 Gigapixels/s, the number of pixels the GPU is capable of outputting every second. Furthermore, it has a texture fill rate of 93 Gigatexels/s, the number of pixels the GPU can renderer per second.

As for rendering API support, the Radeon R9 M390X supports up to DirectX 12. In addition, in cross-platform titles, OpenGL 4.3 features are supported. Newer APIs are usually more efficient, allowing for better performance in games and better graphical effects.

The raw technical specs of the Radeon R9 M390X are: 2048 total shading units (general purpose parallel cores capable of processing different aspects of the graphics pipeline), 128 texture mapping units (specialised processors for texture operations, this determines the texture rate) and 32 render output processors or units (the final step in the rendering pipeline, responsible for rasterising the image)

Power and thermals for the AMD Radeon R9 M390X are a TDP (Thermal Design Power) of 100 watts. This measures the amount of heat the GPU produces when running at 100%. This isn't a measure of power consumption, but it's a good estimate.
