Hardware Used for Realistic Rendering in Virtual World

This paper presents an introduction of the most advanced arhitectures, as the date when the article is presented, of hardware systems developed for graphical acceleration, used in various domains like games industry, graphical simularion or research. A comparation of GPU clock spead and stream processors of the most two advanced graphical cards. Also it presents the programatic stages called „shaders” used for processing unit to optimize the work on a image data. The performance evaluation is based on the idea to use the same algorithm implementation [19] using two different approaches, the first one consists of using the graphical processing unit and the second one, is to use control processing unit on two images of different resolution.
