ATI would go on produce a card in the X series to compete instead. I would recommend this tabbed page to start managing 3D. The card more than surpassed the GT with performance similar to that of the GeForce 6 Used first on the Radeon X, the R was produced on a 0. The solution to retain all 6 vertex units is no less interesting.

The chip was designed for AGP graphics cards. 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. ahi

As such, this chip was obviously designed for a heavier geometry load than texturing, perhaps being tailored for a role as a FireGL chip. Note that the Ultra suffix is still reserved by NVIDIA – considering a great overclocking potential of the nm process, we can expect a video card with the core frequency at about or even MHz, or even in future memory and with the name Ultra.

LOW Standard – enables optimizations for applications as well as the light filtering optimization.

Besides, floating blending and Shaders 3. GPU frequency — MHz. Retrieved 23 March Memory operates at MHz. 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.


An X XT was planned for production, and reviewed by various hardware web sites, but was never released. Perhaps, from the manufacturers’ point of view the solution with a bit bus would be more convenient, at least if they had a choice.

They enable so called rv4100 of drivers for various games, as well as general filtering trilinear and anisotropy optimizations. Part 1 – Performance. Normal and parallax mapping were replacing sheer geometric complexity for model detail, so undoubtedly that was part of the reasoning. We don’t know the answer yet and hope to get explanations from ATI. Apparently by reducing tile sizes, ATI was able to optimize for different triangle sizes.

Coined the “quad dispatch system”, the screen is tiled and work is spread out evenly among the rb410 “quads” to optimize their throughput. Though the number of transistors in the chip is not reduced.

With gv410 that it’s based on a 0. I also want to note aati comfort of sampling frequencies controls: When ATI doubled the number of pixel pipelines, they also raised the number of vertex shader engines from 4 to 6. Considerations about what and why has been cut down On the whole, at present we have the following series of solutions based on NV4X and R4XX: 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. The memory controller and memory bandwidth optimization techniques HyperZ were identical. So, ATI aati still have some issues to improve. All techniques for sparing memory bandwidth – Z buffer and frame buffer compression, Early Z with an on-chip Hierarchical Z, etc.

At first glance it really is. Theoretical texture fetch speed 3.

Radeon X700 Series

Interestingly, unlike NV43, which can perform blending writing not more than 4 resulting pixels per clock, pixel pipelines in RV completely correspond to R in this respect. Strangely, the X mainstream card RV had 6 vertex shaders while only being equipped with 2 quads. Unlike NVIDIA having sufficiently large in terms of transistors ALU array, which is responsible for postprocessing, verification, Z generation, and pixel blending in floating point format, RV possesses modest combinators and that’s why their number was not cut down so much.

A new pixel shader version PS2. Most of the rest of the GPU was extremely similar to R
