These chips are used in numerous mainstream, thin-and-light, and business-class laptops, which are primarily designed with everyday home and office computing in mind, rather than high-performance for demanding games and other intensive tasks. Although it isn’t a high-performance one, the Intel HD 5500 is probably the widest adopted GPU for mobile PCs on the current market, since it is integrated in the popular Intel Core series processors. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.The Intel HD 5500 is the most important graphics processing unit for laptops in 2015. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. Pixel rate is calculated by multiplying the amount of ROPs by the the core clock speed. Pixel Rate: Pixel rate is the most pixels the graphics 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 better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). This is calculated 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 processed per second. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. The better the memory bandwidth, the faster the card will be in general. If it uses DDR type memory, the result should be multiplied by 2 again. The number is calculated by multiplying the interface width by its memory speed. Memory Bandwidth: Bandwidth is the max amount of data (in units of megabytes per second) that can be transported past the external memory interface within a second.
