AMD Radeon RX 570 vs ASRock Phantom Gaming X Radeon RX570 4G OC (PHANTOM GXR RX570 4G OC)

Since two graphics cards have the same number of Raster Operations Pipelines (ROPs), and the ASRock Phantom Gaming X Radeon RX570 4G OC is clocked higher, it also has higher pixel fillrate. 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.

Another important parameter, that influences overall card performance, is texture fillrate. This parameter is proportional to the number of TMUs and graphics frequency. Because both GPUs have the same number of Texture Mapping Units (TMUs) and the ASRock Phantom Gaming X Radeon RX570 4G OC is clocked higher, its texture fillrate is higher. Better maximum texture fill rate allows the GPU to use more sophisticated 3D effects and/or map more textures to each textured picture element, which improves visual appearance of games and generated images.

Maximum Single Precision performance illustrates how fast the graphics card is at running programs, that process primarily single-precision floating point data. The performance is measured in GFLOPS, which stands for Giga (billions of) Floating Point Operations Per Second. Since FP calculations are performed by shaders, CUDA cores or stream processors, the performance is directly proportional to their number. Processor clock rate also affects it. The ASRock Phantom Gaming X Radeon RX570 4G OC graphics card is insignificantly faster here. Higher single-precision performance number means the graphics card 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.

To speed up processing, the cards store 3D scene data, textures and intermediate data, used for image generation, in on-board memory. The video memory usually has much higher bandwidth than system RAM, and more bandwidth allows the graphics card to run at higher screen resolutions, use larger and more detailed textures, and apply more complex 3D effects and filters. The bandwidth is dependent on memory type, speed, and memory interface width. Specifically, the Phantom Gaming X Radeon RX570 4G OC offers higher clocked memory. Consequently, it has a bit higher memory bandwidth.
