Radeon® X1900 Graphics Technology – Overview
Radeon® X1900 Series — The World’s Fastest Consumer Graphics1
Is your rig ready for the onslaught of next generation games? It will be with the Radeon® X1900—the fastest consumer 3D graphics processor on the planet.

Designed from the ground up to deliver maximum graphical detail at the best possible frame rates, the Radeon X1900’s state-of-the-art architecture includes an ultra-threaded engine for unparalleled shader performance. In addition, it is CrossFire™ ready, allowing your greatest multi-GPU fantasies to come true.

The Radeon X1900 ups the ante with Avivo™ video and display technology delivering movies, games, and photos in high-definition format with stunning color and realism.

The World’s Fastest Consumer Graphics Processing Unit (GPU)

The Radeon X1900 conquers the competition with brute force and massive parallelism, including an ultra-threaded engine, high speed memory support, and 90 nanometer technology.

New ultra-threaded engine cranks up performance for a significant improvement over our previous generation GPU: The Radeon X1900’s ultra-threaded engine has 48 individual pixel shader processors and supports incredibly fast memory clock speeds.

Ultra-efficient memory controller squeezes out every last drop of visual detail from your games: Efficient use of memory permits rapid transmission of graphics data. The Radeon X1900’s new ring-bus memory controller provides optimal memory usage for enhanced performance.

90 nanometer technology = maximum performance: Industry-leading 90 nanometer technology has allowed our engineers to pack more features into the graphics chip, resulting in faster frame rates and incredible performance improvements.

Are You Ready to Slide Your Graphics Settings to ‘V. High’?

The Radeon X1900 promises the world’s fastest shader performance in Shader Model 3.0 applications. ATI allows you to 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.

Get your box geared up for the future of games with blazing fast shader performance and watch your characters sweat with Shader Model 3.0 Shaders create the surface properties of 3D objects. The Radeon X1900 has 48 shader processors that work in parallel with Shader Model 3.0 to render complex object surfaces—such as glistening sweat on a character’s skin—with 128-bit floating point precision.

Image Quality
Take the edge off of jagged wires and strands of hair with advanced adaptive anti-aliasing, and experience realistic lighting through HDR technology 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 around buildings or landscape. This added color detail and lighting effect gives you a more true-to-life gaming experience with realistic settings and sequences.

CrossFire
Unite the power of two graphics cards to accelerate your games even further with CrossFire, our acclaimed multi-GPU solution Radeon X1900 series allows you to get incredible gaming performance by adding a Radeon X1900 Crossfire Edition graphics card for ultra fast performance that works with all games, all the time.

Beyond games
There’s more to PC graphics than games, and Avivo — video and display perfection — makes sure you experience it all. Avivo promises a high definition amphitheatre visual experience, delivering sharper photos, smoother video, true-to-life image representation, and universal display connectivity.

High-definition images come to life with remarkable clarity and over 1 billion colors Avivo’s 10-bit-per-color display engine renders more than one billion colors, resulting in images that are clean, sharp, and incredibly realistic.

Avivo’s universal connectivity allows you to create your ideal display set-up In addition to supporting multiple monitor environments and accommodating virtually any type of display, Avivo can allow your PC to become the core of your home theater by leveraging ATI’s Xillion and Theater technologies, which are found inside many of today’s best digital TVs.

Avivo uses the same technologies present in digital TVs to deliver HD image quality for a high-end home theatre experience Avivo uses proprietary video scaling technology to display crystal clear images on high resolution displays. Movies and images sent to your display will be hardware accelerated for superb, stutter-free viewing.
