Current technologies and software. R was actually a secondary 4th generation project for ATI, with the original R plan being scrapped. This page was last edited on 14 October , at Com, December 1, , retrieved January 17, R was unable to reach high clock speeds, being mainly designed to reduce the cost per GPU, and so a new top-of-the-line core was still needed.

When ATI doubled the number of pixel pipelines, they also raised the number of vertex shader engines from 4 to 6. Retrieved from ” https: Archived from the original on RV used a layout consisting of 8 pixel pipelines connected to 4 ROPs similar to GeForce 6 while maintaining the 6 vertex shaders of X Archived copy as title Pages using deprecated image syntax.

Com, October 20, ATI would go on produce a card in the X series to compete instead. The new high-end R4x0-generation arrived with the X series, equipped with various core tweaks for slightly higher performance than the “R”-based X series. Driver support of this core was discontinued as of Catalyst 9. InATI had a large number of dies that “worked” but not well enough to be used on the X or X series cards.

R basically takes a “wider is better” approach to the previous r4880, with some small tweaks thrown in to enhance it in various ways.

From Wikipedia, the free encyclopedia. Com, December 1,retrieved January 17, ATI Technologies products Video cards.

atii ATI showcased many of their chip’s new features in the promotional real-time demo called, Ruby: This new revision to PS2. With R’s and RV’s 6 vertex shaders combined with higher clock speeds than the previous generation, ATI was able to more than double the geometry processing capability of XT. Views Read Edit View history. Essentially, the X Pro is built on semi-defective R cores.

Coined the “quad dispatch system”, the screen is tiled and work is spread out evenly among the separate “quads” to optimize their throughput. Current technologies and software. The chip came equipped with over double the pixel and vertex pushing resources compared to the Radeon XT’s R a minor evolution of the Rwith 16 DirectX 9.

The earliest Radeon X series cards were based on the R core. Note, ATI’s “Temporal AA” was actually a temporal dithering filter for spatial AA, not de facto temporal anti-aliasing which must involve a controlled blending of the temporal subsamples from consecutive screens.

An X XT was planned for production, and reviewed by various hardware web sites, but was never released. Com forum, November 11, Most of the rest of the GPU was extremely similar to R Although the Rbased chips are fundamentally similar to Rbased cores, ATI did tweak and enhance the pixel shader units for more flexibility.

The R design was a 4 “quad” arrangement 4 pipelines per quad. Com, May 4, R was actually a secondary 4th generation project for ATI, with the original R plan being scrapped. Strangely, the X mainstream card RV had 6 vertex shaders while only being equipped with 2 quads. A 2X software setting became perceptively equivalent to 4X.
