ATI R480 DRIVER

Software making heavy use of normal mapping could gain a significant speed boost from the savings in fillrate and bandwidth by using 3Dc. Com, December 1, , retrieved January 17, The R design was a 4 “quad” arrangement 4 pipelines per quad. Com, May 4, R basically takes a “wider is better” approach to the previous architecture, with some small tweaks thrown in to enhance it in various ways. Essentially, the X Pro is built on semi-defective R cores. 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

This card usually came with a 3 quad configuration, like X Atj. The “R”-based X line was available in 3 forms: The R design was a 4 “quad” arrangement 4 pipelines per quad. The card more than surpassed the GT with performance similar to that of the GeForce 6 Views Read Edit View history.

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. Coined the “quad dispatch system”, the screen is tiled and work is spread out evenly among the separate “quads” to optimize their throughput.

A 2X software setting became perceptively equivalent to 4X. Apparently by reducing tile sizes, ATI was able to optimize for different triangle sizes.

Used first on the Radeon X, the R was produced on a 0. Because DirectX Texture Compression DXTC was block-based and not designed for a normal map’s different data properties, a new compression method was needed to prevent loss of detail and other artifacting.

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. D480 from the original on Com, October 20, Atu Technologies products Video cards.

Another notable addition to the core was a new kind of normal map compression, dubbed ” 3Dc “. This new revision to PS2.

As such, this chip was obviously designed for a heavier geometry load than texturing, perhaps being tailored for a role as a FireGL chip. Although the Rbased chips are fundamentally r4880 to Rbased cores, ATI did tweak and enhance g480 pixel shader units for more flexibility.

Com, May 4, Driver support of this atl was discontinued as of Catalyst 9. An X XT was planned for production, and reviewed by various hardware web sites, but was never released.

Strangely, the X mainstream card RV had 6 vertex shaders while only being equipped with 2 quads. The memory controller and memory bandwidth optimization techniques HyperZ were identical. Normal and parallax mapping were replacing sheer geometric complexity for model detail, so undoubtedly that was part of the reasoning.

Current technologies and software.

The new high-end R4x0-generation arrived with the X series, equipped with various core tweaks for ato higher performance than the “R”-based X series.

Software making heavy use of normal mapping could gain a significant speed boost from the savings in fillrate and bandwidth by using 3Dc.

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.

If the framerate could not be maintained, the driver will disable Temporal AA. Essentially, the X Pro is built on semi-defective R cores. 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 d480 capability of XT.

The chip was designed for AGP graphics cards. Com forum, November 11, R was actually a secondary 4th generation project atj ATI, with the original R plan being scrapped.

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
