The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The number is worked out by multiplying the number of ROPs by the the core clock speed. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. It is measured in millions of texels per second. The higher this number, the better the video 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 clock speed of the chip. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. It also takes advantage of NVIDIA® Optimus technology to give you the performance you need without compromising battery life. It especially helps with anti-aliasing, HDR and higher screen resolutions. GeForce® 920M raises the bar for entry laptops with up to 3X faster graphic performance for games, photo, and video-editing applications. The higher the card's memory bandwidth, the better the card will be in general.
If it uses DDR RAM, it should be multiplied by 2 again. The number is worked out by multiplying the interface width by its memory clock speed. Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be transferred past the external memory interface within a second.
