Maxsun Radeon RX 550 Transformers 4G vs PowerColor Red Dragon Radeon RX 550 2GB GDDR5 (AXRX 550 2GBD5-DH)

 

 

Maximum Single Precision performance indicates how many single-precision floating point operations the GPU can execute per second. The performance is expressed in billions of Floating Point Operations Per Second, or GFLOPS. Since FP calculations are performed by shaders, CUDA cores or stream processors, the performance is directly proportional to their number. It also depends on the processor clock. The PowerColor Red Dragon Radeon RX 550 2GB GDDR5 card has an upper hand here. Higher single-precision performance number means the graphics card will perform better in general computing applications. Since stream processors or CUDA cores are also used as vertex and geometry shaders for 3D image generation, higher performance is also beneficial to games.

To speed up processing, the GPUs 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 display resolutions, use larger and more detailed textures, and apply more complex 3D effects and filters. The bandwidth is dependent on memory type, speed, and width of memory interface. Specifically, the Radeon RX 550 Transformers 4G GPU comes with higher memory clock. As such, it has higher memory bandwidth.
