ATi Technologies heeft vandaag de Radeon 256 aangekondigd. Hiermee worden eerdere vermoedens over de officiële naam van de Rage6 bevestigd. De specs van de Radeon 256 zijn niet fout: max 128MB/200MHz DDR SDRAM, 30 miljoen triangles per sec en een theoretische fillrate van 1,5Gigapixel/s. Hierbij moet wel rekening gehouden worden met het feit dat de twee rendering pipelines van Radeon 3 texels per kloktik kunnen verwerken. Bij gebruik van multi-texturing komt je dus uit op een theoretische fillrate van 1Gigapixel/s, wat in vergelijking met de GeForce2 GTS en Voodoo5-6000 al weer een stukkie minder heftig overkomt. Verder heeft de Radeon 256 wel een aantal interessante beeldkwaliteit bevorderende features, zoals 3D texture support, EMBM en dot product 3 bumpmapping, 3D shadows en pixel shaders:
ATI Technologies Inc. (TSE: ATY, NASDAQ: ATYT) today introduced the most powerful graphics processor ever designed for desktop PCs, the RADEON 256™ at Microsoft's annual Windows Hardware Engineering Conference (WINHEC).The new chip is a quantum step forward in 3D acceleration for both high-end gaming and 3D workstation graphics. RADEON 256 has the world's fastest hardware transformation, clipping and lighting (T&L) geometry engine and will drive the creation of an entirely new generation of 3D applications and content.
[...] The new chip supports the following firsts:
- Most advanced graphics chip ever designed, featuring 30 million transistors, in an .18 micron technology, giving it a higher transistor count than CPUs such as the Pentium III and Athlon.
- First chip to support up to 128MB of double-data rate (DDR) memory at 200MHz
- ATI's Charisma Engine™ which incorporates a 30 million triangle per second geometry engine as well as radical new 3D character animation techniques
- First graphics chip to break through the Gigatexel barrier with an awesome 1.5 Gigatexel per second rendering engine
- First PC graphics chip to include an on-chip hardware HDTV decoder
[...] At the core of the RADEON 256 GPU is a trio of new technologies unique to ATI: The Charisma Engine for geometry processing, Pixel Tapestry™ for rendering, and Video Immersion™ for digital video.
Charisma Engine: ATI's Geometry Engine
Charisma combines the world's fastest geometry engine along with revolutionary new techniques for bringing 3D characters to life. The geometry engine supports full transformation, clipping, and lighting (T&L) at 30 million per second processing capability, resulting in a 10x improvement in 3D modeling detail relative to current CPU based geometry. Charisma supports cutting-edge character animation features, such as advanced vertex skinning and key frame interpolation. These effects are required in bringing game characters to life with realistic behaviors, fluid movements, and believable facial expressions including lip-synching.
Pixel Tapestry: ATI's Rendering Engine
Pixel Tapestry combines the world's fastest rendering engine along with an unprecedented new set of 3D special effects. It is the first graphics chip to break through the Gigatexel barrier with an awesome 1.5 Gigatexel per second rendering engine. The new chip's ability to process up to 3-textures concurrently, means unsurpassed performance in accelerating the coming wave of multi-textured game content. Because of its awesome rendering capability, RADEON 256 enables full performance in 32-bit color, which finally makes 16-bit color obsolete.
The list of unique features in Pixel Tapestry includes:
- First with 3D texture support for new volumetric effects
- First with all DX7 bump mapping effects (emboss, dot product 3 and EMBM)
- First with hardware support for 3D shadows
- First with advanced DX8 pixel shader effects
- Comprehensive support for full scene, order-independent anti-aliasing
