The Most Advanced 3D Performance Arsenal
Get the ultimate gaming performance AND image quality with an advanced ultra-threaded 3D architecture, a ruthlessly efficient memory controller and Shader Model 3.0, all enabled by the most advanced 90 nanometer GPU process.
* Radeon X1800 Series excels with Shader Model 3.0, HDR and adaptive anti-aliasing
Radeon X1800 series’ 90-nanometer process technology and ultra-threaded architecture combine power and efficiency as well as support for Shader Model 3.0 to deliver new High Dynamic Range visual effects, enhanced realism with Adaptive Anti Aliasing and lightening fast performance in OpenGL and DirectX® 9 games.
CrossFire: Multiply and Conquer with Multi-GPU Performance
Designed from the ground up with GPU sharing in mind, the Radeon X1800 series allows you to get incredible gaming performance by adding a Radeon X1800 Crossfire Edition graphics card for ultra fast performance that works with all games, all the time.
* Supertiling for optimized gaming performance
CrossFire’s “supertiling” GPU sharing speeds rendering by evenly dividing the graphics processing, intelligently alternating the rendering workload to each Radeon GPU for efficient load balancing, and optimized performance.
* CrossFire boosts image quality
CrossFire boosts image quality along with rendering speed, eliminating the need to crank down screen resolutions to get the high image quality you want.
CrossFire ignites with the higher anti-aliasing, anisotropic filtering, shading, and texture settings you desire. Adjust your display configurations, experiment with your advanced 3D settings, and check the effect with a real-time 3D-rendered preview within ATI’s Catalyst Control Center to rule your CrossFire system.
* Upgradeable components and web support
CrossFire supports a wide range of ATI-based graphics cards and motherboards, and offers compatibility with a broad array of third party components for a flexible and robust solution.
o Upgradeable components allow you to gradually improve your system performance with the reliability and support that only ATI delivers.
o Free monthly on-line Catalyst software updates, ATI’s one-click comprehensive help system, and web-based online customer support are available 24 hours per day.
High Definition Image Quality with Avivo
Connect your Radeon X1800 with your home entertainment devices for high definition convergence, enhanced with ATI’s revolutionary new Avivo video and display technology platform. Avivo technology creates vibrant colors, ultra sharp images, true-to-life image reproduction, and the smoothest HD video playback ever offered by ATI.
Avivo redefines the ultimate visual experience for today’s PCs, and sets the stage for tomorrow’s exciting possibilities. Check your board for specific support of Avivo features.
* Sharp video and photos
Avivo enhances your digital video and photos, creating sharp images, crisp text, and vivid color. Boost the video quality captured by your Media PC and Personal Video Recorder with advanced 3D comb filtering and automatic gain control. Improve analog video signal quality and reduce annoying artifacts. Maintain clean images even at high display resolutions with Avivo’s video scaling technology.
* True-to-Life Image Reproduction
Get high image fidelity with CRT and LCD displays, TVs, rear projection and plasma TVs, as well as projectors. Avivo introduces new life to colors across the entire spectrum with an advanced 10-bit-per-color display engine. Gain better digital signal reception, and maintain cleaner video with hardware noise reduction. Enjoy high-quality analog video capture enabled by robust 12-bit analog-to-digital converters.
* Smooth Video Playback
Free your CPU to devote more processing power to other applications with Avivo’s hardware accelerated processing of new HD video formats, including H.264. Transform your movies and improve every image sent to your display with hardware post processing for superb stutter-free viewing. Avivo gives your video playback the smooth, fluid motion you want from your HD content.
* Universal Display Connectivity
Certain ATI graphics cards with Avivo technology can dissolve connectivity barriers between PCs and consumer electronic devices. Outputs for virtually any TV via analog or digital interface, such as s-video, and DVI , are complemented by inputs for cable, broadcast TV and other video sources. And advanced dual-link DVI interfaces support the largest high-resolution LCD displays.
ATI’s Catalyst: Power and Control

X 1800:
An independent team of Finnish over-clockers has made world history by over-clocking a graphics processor to engine clock levels above 1 GHz. The record was set on the recently-announced Radeon® X1800 XT graphics processor from ATI. Noted Finnish over-clockers Sampsa Kurri and Ville Suvanto achieved graphics engine clocks of 1.003 GHz and a memory speed of 1.881 GHz (940.50 MHz DDR (dual data-rate) memory clocks) with maximum system stability and no visual artifacts.
The team, optimistic that higher speeds could ultimately be achieved with the Radeon X1800 XT, attained the record speeds using a custom-built liquid nitrogen cooling system that cooled the graphics processor to minus-80 degrees Celsius. "We're just warming up," joked Kurri. "But we believe that the Radeon X1800 XT has even more over-clocking headroom, and in the coming weeks we expect to achieve higher clock speeds and even greater performance levels."
"It's impressive to see the Radeon X1800 XT architecture achieve 1 GHz core speed and approach 2 GHz memory speed, which far exceeds the specifications of the memory devices," said Stan Ossias, Sr. Product Manager, Desktop Products, ATI Technologies Inc. "Once faster GDDR-4 memory arrives next year, users can expect to see the hidden potential of ATI's innovative new memory controller design complement our powerful shader engines with massive additional memory clock scalability."

Radeon X1800 XT's extreme clock-scaling capabilities are made possible by a series of key innovations that include use of the state-of-the-art 90-nanometer semiconductor process technology, an efficient new Ultra-threaded Shader Model 3.0 architecture, and a revolutionary new 512-bit ring-bus memory controller.

The RADEON X1600-series is expected to substitute RADEON X700 family of graphics chips as well as to replace the RADEON X800 GT and possibly the RADEON X800 XL (or GTO2) products from performance mainstream segment. The obvious advantage the RADEON X1600 has over predecessors is support for Shader Model 3.0, HDR and some other technologies. The probably disadvantage is 128-bit memory bus as well as pretty low texel-rate. We will find out the outcome later in the article, but now let’s summarize everything we know about the RADEON X1600 also known as RV530, based on the results in synthetic investigation.
