ATI R GPU |
Current technologies and software. This new revision to PS2.
Com, December 1,retrieved January 17, ATI would go on produce a card in the X series to compete instead. A 2X software setting became perceptively equivalent to 4X. However, r408 games which this performance level could be maintained, Temporal AA was a nice addition to ATI’s excellent anti-aliasing options.
Driver support of this core was discontinued as of Catalyst 9.
Com forum, November 11, 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 Essentially, the X Pro is built on semi-defective R cores. Used first on the Radeon X, the R was produced on a 0. Software making heavy use of normal r408 could gain a significant speed boost from the savings in fillrate and bandwidth by using 3Dc. Archived from the original on Most of the rest of the GPU was extremely similar to R Retrieved from ” https: The new high-end R4x0-generation arrived with the X series, equipped with various core tweaks atl slightly higher performance than the “R”-based X series.
ATi R GPU – Specifications, and Pictures –
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. Although the Rbased chips are fundamentally similar to Rbased cores, ATI did tweak and enhance the pixel shader units for more flexibility. Apparently by reducing tile sizes, ATI was able to optimize for different triangle sizes.
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.
This is how the Rseries chips performed their tasks as well, but R refined this by allowing programmable tile sizes in order to control work flow on a finer level of granularity.

Similar to how texture compression had been part of the Direct3D specification for years and was used for compressing regular textures, normal map compression compacted this new type of surface detail layer. R basically takes a “wider is better” approach to the previous architecture, with some small tweaks thrown in to enhance it in various ways. The R design was a 4 “quad” arrangement 4 pipelines per quad. An X XT was planned for production, and reviewed by various hardware web sites, but was never released.
Atk ATI doubled the number of pixel pipelines, they also raised the number of vertex shader engines from 4 to 6. With R’s and RV’s 6 vertex shaders combined atti higher clock speeds than the previous generation, ATI was able to more than double the geometry processing capability of XT. Normal and parallax mapping g480 replacing sheer geometric complexity for model detail, so undoubtedly that was part of the reasoning. Archived copy as title Pages using deprecated image syntax. R was actually a secondary 4th generation project for ATI, with the original R plan being scrapped.
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. Com, October 20,
