![]() compare prices and read user reviews for Notebooks with GPU - NVIDIA GeForce: GTX 860M. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate. compare prices and read user reviews for Notebooks with GPU - NVIDIA GeForce: GTX 860M.

ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The number is calculated by multiplying the number of Render Output Units by the clock speed of the card. Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. It is measured in millions of texels processed in a second. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). This number 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 amount of texture map elements (texels) that are applied in one second. It especially helps with AA, HDR and high resolutions. The higher the card's memory bandwidth, the faster the card will be in general. ![]() In the case of DDR type memory, the result should be multiplied by 2 again. The number is worked out by multiplying the card's interface width by its memory speed. Memory Bandwidth: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be moved over the external memory interface in a second.
