MSI GeForce GT 730 4GB V2 vs GT 730 OC LP 2GB GDDR5

There are two characteristics that influence the maximum theoretical pixel fillrate. These are the number of ROPs and graphics clock rate. The GeForce GT 730 OC LP 2GB GDDR5 has a substantial lead here, as it has twice as many Raster Operations Pipelines (ROPs), and runs at higher frequency. Better pixel fill rate allows more pixels to be drawn on screen per second, which results in increased GPU performance, unless the graphics card is limited by something else, such as texture mapping or memory bandwidth.

Pixel fill rate was an essential parameter years ago, but not so much these days. Texture fill rate has more significance in modern games. This fillrate is proportional to the number of TMUs and graphics frequency. The MSI GeForce GT 730 OC LP 2GB GDDR5 has an upper hand here, because it operates at higher rate, and both cards have identical number of Texture Mapping Units. Having better texture fill rate allows the GPU to map more textures and/or utilize more complex 3D effects for each texel, which improves visual appearance of games and generated images.

Maximum Single Precision performance indicates 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. All single-precision calculations are performed by CUDA cores or stream processors, therefore the more cores / processors the graphics card has the better. Performance also depends on the processor clock speed. The GeForce GT 730 OC LP 2GB GDDR5 GPU is significantly faster 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 graphics 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 GPU to run at higher display resolutions, use larger and more detailed textures, and apply more complex 3D effects and filters. Memory type, speed, and memory interface width all affect the bandwidth value. Specifically, higher memory bandwidth of the MSI GeForce GT 730 OC LP 2GB GDDR5 graphics card is due to better and higher clocked memory.
