AMD Radeon RX 480 vs MSI Radeon RX 550 2GT LP OC

Because it has twice as many Raster Operations Pipelines (ROPs), the Radeon RX 480 provides considerably higher pixel fill rate, even though its graphics clock is slower. 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 so it has lower graphics frequency, the AMD Radeon RX 480 card comes with many more TMUs, resulting in significantly better texture fill rate. Better texture fill rate means that the GPU can use more sophisticated 3D effects and/or map more textures to each textured picture element, which improves games visual appearance.

Single Precision performance is useful for estimating card's maximum speed in programs, that process mainly single-precision floating point data. The performance is expressed in billions of Floating Point Operations Per Second, or GFLOPS. As a rule, the faster CUDA cores or stream processors run at, and the more cores / processors the graphics unit has, the higher Single Precision performance will be. The AMD Radeon RX 480 is much faster here. Higher single-precision performance number means the GPU 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 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 depends on memory type, speed, and width of memory interface. Specifically, the AMD Radeon RX 480 graphics card offers higher clocked memory and wider bus. As a result, it has more memory bandwidth.
