The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The figure is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip 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 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 texture units by the core speed of the chip. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. The better the memory bandwidth, the better the card will be in general. If it uses DDR type RAM, it must be multiplied by 2 once again. The number is calculated by multiplying the bus width by its memory clock speed.

Compare those specs to the GeForce GTX 1050, which has a core clock frequency of 1354 MHz and a GDDR5 memory frequency of 1750 MHz. It is made up of 384 SPUs, 24 TAUs, and 8 Raster Operation Units. It also uses a 64-bit memory bus, and uses a 28 nm design.

Memory Bandwidth: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be transported across the external memory interface in one second. The GeForce 930M has a core clock frequency of 928 MHz and a DDR3 memory speed of 900 MHz.
