![]() The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. 279.99 Genuine New Graphics Video Card NVIDIA GeForce GTX 860M GDDR5 2GB for Alienware 13 R1 18 17 R1 R2 R3 M17X R2 R4 M18X R2 R3 Gaming Laptop, N15P-GX-B-A2 MXM VGA GPU Board Replacement Parts. ![]() Pixel rate is calculated by multiplying the number of Render Output Units by the the card's clock speed. GeForce GTX 860M 1,895.00 HP OMEN 15.6 Inch Laptop (Intel Core i7, 8 GB, 256 GB SSD, Black) NVIDIA GeForce GTX 860M. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. It is measured in millions of texels applied per second. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). This is calculated by multiplying the total texture units of the card by the core speed of the chip. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. It especially helps with anti-aliasing, HDR and higher screen resolutions. The better the card's memory bandwidth, the better the card will be in general. In the case of DDR type memory, it must be multiplied by 2 again. It is calculated by multiplying the card's interface width by its memory clock speed. Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be moved past the external memory interface in a second. ![]()
