![]() The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach 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 number is worked out by multiplying the number of Render Output Units by the the core speed of the card. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. It is measured in millions of texels applied in one second. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). ![]() This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. The higher the memory bandwidth, the faster the card will be in general. If the card has DDR memory, the result should be multiplied by 2 again. It is worked out by multiplying the card's bus width by its memory speed. Our figures are checked against thousands of individual user ratings. ![]() Effective speed is adjusted by current prices to yield value for money. We calculate effective 3D speed which estimates gaming performance for the top 12 games. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be moved over the external memory interface in one second. Graphics Card Rankings (Price vs Performance) September 2023 GPU Rankings. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The number is worked out by multiplying the number of ROPs by the the core speed of the card. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics 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 per second. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). This number is calculated by multiplying the total texture units of the card by the core speed of the chip. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. It especially helps with AA, HDR and higher screen resolutions. 750 Ti outperforms 750 by 16 in our combined benchmark results. The better the memory bandwidth, the better the card will be in general. We are regularly improving our combining algorithms, but if you find some perceived inconsistencies, feel free to speak up in comments section, we usually fix problems quickly. In the case of DDR type memory, it should be multiplied by 2 once again. It's calculated by multiplying the interface width by the speed of its memory. Memory Bandwidth: Bandwidth is the max amount of information (counted in megabytes per second) that can be transferred over the external memory interface in a second.
