The state-of-the-art architecture includes an ultra-threaded engine for unparalleled shader performance. With Avivo™ video and display technology the X1900 delivers movies, games, and photos in high-definition format with stunning color and realism.The card is built on a 90 nanometer technology. The ultra-threaded engine has 48 individual pixel shader processors and supports incredibly fast memory clock speeds.

The Radeon X1900’s new ring-bus memory controller provides optimal memory usage for enhanced performance. It promises the world’s fastest shader performance in Shader Model 3.0 applications. Also you can experience simultaneous HDR and advanced anti-aliasing effects for incredible enhancements to lighting contour and colour details, delivering the ultimate in visually immersive 3D gaming.

The Radeon® X1K family are the only graphics boards on the market to combine Full Screen Antialiasing (FSAA), the most advanced anti-aliasing technique in the world, with high dynamic range (HDR) technology. HDR mimics the function of the human eye by allowing for a broader range of colors within a scene. This allows for more color, giving a wider spectrum of lighting effects and providing realistic shadows.This added color detail and lighting effect gives you a more true-to-life gaming experience with realistic settings and sequences.
