The ATI Rage line powered almost the entire range of ATI graphics products. In particular, the Rage Pro was one of the first viable 2D-plus-3D alternatives to 3dfx 's 3D-only Voodoo chipset. 3D acceleration in the Rage line advanced from the basic functionality within the initial 3D Rage to a more advanced DirectX 6.0 accelerator in 1999 Rage 128 .
The R420 GPU, developed by ATI Technologies, was the company's basis for its 3rd-generation DirectX 9.0/OpenGL 2.0-capable graphics cards. Used first on the Radeon X800, the R420 was produced on a 0.13 micrometer (130 nm) low-K photolithography process and used GDDR-3 memory. The chip was designed for AGP graphics cards.
The R200 is the second generation of GPUs used in Radeon graphics cards and developed by ATI Technologies. This GPU features 3D acceleration based upon Microsoft Direct3D 8.1 and OpenGL 1.3, a major improvement in features and performance compared to the preceding Radeon R100 design. The GPU also includes 2D GUI acceleration, video acceleration ...
You'd think with ATI having the performance, value and power efficiency lead for so long -- at least since the Radeon HD 4000 series -- NVIDIA would be in all kinds of trouble, but it's only now ...
Launch – Date of release for the GPU. Architecture – The microarchitecture used by the GPU. Fab – Fabrication process. Average feature size of components of the GPU. Transistors – Number of transistors on the die. Die size – Physical surface area of the die. Core config – The layout of the graphics pipeline, in terms of functional ...
The Radeon R100 is the first generation of Radeon graphics chips from ATI Technologies.The line features 3D acceleration based upon Direct3D 7.0 and OpenGL 1.3, and all but the entry-level versions offloading host geometry calculations to a hardware transform and lighting (T&L) engine, a major improvement in features and performance compared to the preceding Rage design.
Previous GPU architectures implemented fixed-pipelines, i.e. there were distinct shader processors for each type of shader. TeraScale leverages many flexible shader processors which can be scheduled to process a variety of shader types, thereby significantly increasing GPU throughput (dependent on application instruction mix as noted below).
The first graphics cards using the R300 to be released were the Radeon 9700. It was the first time that ATI marketed its GPU as a Visual Processing Unit (VPU). R300 and its derivatives would form the basis for ATI's consumer and professional product lines for over 3 years. The integrated graphics processor based upon R300 is the Xpress 200.
