The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's clock speed. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. It is measured in millions of texels in a second. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. ![]() It especially helps with AA, High Dynamic Range and higher screen resolutions. The higher the card's 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 is calculated by multiplying the card's bus width by its memory clock speed. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.Memory Bandwidth: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transported past the external memory interface within a second. Compare all of that to the GeForce GTX 750 Ti, which has a core clock frequency of 1020 MHz and a GDDR5 memory speed of 1350 MHz. CHOOSE A COMPONENT: CPU GPU SSD HDD RAM MBD. Custom PC Builder (Start a new build) Build your perfect PC: compare component prices, popularity, speed and value for money. It features 512 SPUs along with 32 Texture Address Units and 16 ROPs. Based on 369,635 user benchmarks for the Nvidia GeForce GT 630 and the GTX 750-Ti. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The GeForce GTX 750 features clock speeds of 1020 MHz on the GPU, and 1250 MHz on the 1024 MB of GDDR5 RAM. The number is calculated by multiplying the amount of ROPs by the clock speed of the card. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. ![]() It is measured in millions of texels processed in one second. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. It especially helps with AA, HDR and high resolutions. The higher the memory bandwidth, the faster the card will be in general. If it uses DDR type memory, the result should be multiplied by 2 again. It's worked out by multiplying the card's interface width by its memory speed. Memory Bandwidth: Bandwidth is the max amount of information (counted in megabytes per second) that can be transferred across the external memory interface in one second.
