The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability 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 worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. It is measured in millions of texels in one second. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). This figure 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 number of texture map elements (texels) that are applied per second.
It especially helps with anti-aliasing, HDR and higher screen resolutions. The higher the card's memory bandwidth, the faster the card will be in general. If it uses DDR type RAM, the result should be multiplied by 2 again. (2.50GHz) NVIDIA GeForce GTX 1650 Max-Q 8GB Memory 256 GB NVMe SSD Windows 10 Home 64-bit Gaming Laptop. The number is worked out by multiplying the card's bus width by its memory speed. Memory Bandwidth: Bandwidth is the maximum amount of data (counted in MB per second) that can be transported over the external memory interface in a second.
