AMD Radeon RX 580 vs MSI GeForce GTX 1060 Gaming X 6G

The GeForce GTX 1060 Gaming X 6G has many more ROPs than the Radeon RX 580. Furthermore, its graphics clock speed is higher, therefore it is not surprising to see that its pixel fillrate is considerably higher. Having better pixel fillrate allows the GPU to draw more pixels on screen and off screen, which is beneficial for some 3D effects in games, or when playing at higher display resolutions.

Even though it has lower graphics frequency, the AMD Radeon RX 580 comes with many more TMUs, resulting in better texture fill rate. Better texture fill rate means that the card can map more textures and/or use more sophisticated 3D effects for each textured picture element, which improves games visual appearance.

Maximum Single Precision performance illustrates how many single-precision floating point operations the graphics card can execute per second. The performance is measured in billions of Floating Point Operations Per Second, or GFLOPS. As a rule, the more CUDA cores or stream processors the GPU has, and the the faster they run at, the higher Single Precision performance will be. The AMD Radeon RX 580 has an upper hand here. Higher single-precision performance number means the graphics unit will perform better in general computing applications. Since CUDA cores or stream processors are also used as vertex and geometry shaders for 3D image generation, higher performance is also beneficial to games.

Memory bandwidth parameter specifies how much memory (in Gigabytes) the graphics card can read from or write to dedicated memory per second. Cards with higher memory bandwidth have better performance at high display resolutions, or when using large and detailed textures, and/or utilizing complex 3D effects and filters, like anti-aliasing. The bandwidth is dependent on several components, such as memory type, speed, and memory interface width. Specifically, the AMD Radeon RX 580 comes with wider memory bus. As a consequence, it has higher memory bandwidth.
