AMD Radeon R7 240 vs HIS Radeon R5 230 iCooler (H230F1G)

The maximum theoretical pixel fillrate depends on the number of ROPs (Raster Operations Pipelines) and graphics frequency. The Radeon R7 240 has a substantial lead in this area, as it runs at higher rate and has twice as many ROPs. Better pixel fill rate allows more pixels to be drawn on screen per second, which results in increased performance, unless the card is limited by something else, such as texture mapping or memory bandwidth.

Since the Radeon R7 240 has many more TMUs and higher graphics clock, it has much higher texture fillrate. Better maximum texture fill rate means that the GPU can utilize more complex 3D effects and/or map more textures to each textured picture element, which improves games visual appearance.

Single Precision performance is convenient for figuring out card's maximum speed in programs, that process only single-precision floating point data. The performance is measured in GFLOPS, which stands for Giga (billions of) Floating Point Operations Per Second. Generally, the more stream processors or CUDA cores the graphics unit has, and the the faster they operate at, the higher Single Precision performance will be. The Radeon R7 240 has a massive advantage 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 tells how much memory (in Gigabytes) the graphics card can read from or write to dedicated memory per second. GPUs 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 memory type, speed, and memory interface width. Specifically, the AMD Radeon R7 240 graphics card offers higher memory clock and wider bus. As a result, it has more memory bandwidth.
