The actual pixel output rate is also dependant 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. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. Pixel rate is worked out by multiplying the number of ROPs by the the core clock speed. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. ![]() It is measured in millions of texels processed in one second. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). This figure is worked out by multiplying the total amount of 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 can be processed in one second. Difference: 54960 (133) 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. It especially helps with anti-aliasing, HDR and higher screen resolutions. AMD has set the core frequency at 1968 MHz. Compare all of that to the Radeon RX 6600 XT, which makes use of a 7 nm design. It also is comprised of 1536 SPUs, 128 Texture Address Units, and 32 ROPs. The better the card's memory bandwidth, the better the card will be in general. The Geforce GTX 770 features a GPU clock speed of 1046 MHz, and the 2048 MB of GDDR5 memory runs at 1753 MHz through a 256-bit bus. Compare that to the Radeon HD 7850, which features clock speeds of 860 MHz on the GPU, and 1200 MHz. It is made up of 1536 SPUs, 128 Texture Address Units, and 32 ROPs. It also uses a 256-bit memory bus, and makes use of a 28 nm design. Ray tracing is an advanced light rendering technique that provides more realistic lighting, shadows, and reflections in games. If the card has DDR RAM, it must be multiplied by 2 again. The Geforce GTX 770 comes with a core clock speed of 1046 MHz and a GDDR5 memory frequency of 1753 MHz. It's worked out by multiplying the bus width by the speed of its memory. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.Memory Bandwidth: Memory bandwidth is the largest amount of information (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 number of Render Output Units by the the card's clock speed. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. GeForce GTX 770 MSI Lightning Edition graphics card Gaming performance vs system requirement comparison. It is measured in millions of texels processed per second. GTX 780 c th l high-end ca b card ha Kepler. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. It especially helps with AA, HDR and high resolutions. The better the bandwidth is, the better the card will be in general. If the card has DDR type memory, it should be multiplied by 2 once again. It is worked out by multiplying the bus width by its memory clock speed. ![]() Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be moved over the external memory interface within a second.
