![]() The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The figure is worked out by multiplying the amount of Render Output Units by the the card's clock speed. Comparison of the technical characteristics between the graphics cards, with Nvidia GeForce GTX 750 Ti on one side and Gigabyte GeForce GT 730 GV-N730-2GI. Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. It is measured in millions of texels applied in one second. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. It especially helps with anti-aliasing, HDR and high resolutions. The higher the bandwidth is, the better the card will be in general. Difference: 480 (3) Please note that the above benchmarks are all just theoretical - the results were calculated based on the cards specifications, and real-world performance may (and probably will) vary at least a bit. In the case of DDR type RAM, it must be multiplied by 2 once again. The number is calculated by multiplying the interface width by its memory clock speed. ![]() The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of MB per second) that can be transferred over the external memory interface within a second. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. It is measured in millions of texels in one second. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). This figure is calculated by multiplying the total number of texture units by the core speed of the chip. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. It especially helps with AA, High Dynamic Range and higher screen resolutions. RTX 40 Series RTX 30 Series RTX 20 Series GTX 16 Series GTX 10 Series. The higher the memory bandwidth, the better the card will be in general. If the card has DDR type memory, it must be multiplied by 2 once again. It's calculated by multiplying the card's bus width by its memory clock speed. Memory Bandwidth: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be transferred over the external memory interface within a second.
