Construida principalmente para portátiles medianos-grandes, la tarjeta se posiciona en la categoría de rendimiento a partir de 2013. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.La AMD Radeon HD 8850M es una tarjeta de video de 28nm, compatible con DirectX 11, basada en la arquitectura GCN (Graphics Core Next). ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The figure is calculated by multiplying the number of ROPs by the clock speed of the card. Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. It is measured in millions of texels applied in a second. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF).
This number 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 are processed in one second.
It especially helps with anti-aliasing, HDR and higher screen resolutions. The better the card's memory bandwidth, the faster the card will be in general. In the case of DDR memory, it should be multiplied by 2 once again. It is worked out by multiplying the card's interface width by the speed of its memory. Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be moved over the external memory interface in one second.
