This new revision to PS2. Support in this table refers to the most current version. 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. Strangely, the X mainstream card RV had 6 vertex shaders while only being equipped with 2 quads. An X XT was planned for production, and reviewed by various hardware web sites, but was never released.

Occasionally, it’s also possible to find ways of doing things that enhance the performance of the final product as well. See article on R’s pixel shaders. The card more than surpassed the GT with performance similar to that of the GeForce 6 When ATI doubled the number of pixel pipelines, they also raised the number of vertex shader engines from 4 to 6. Some people didn’t expect it to happen this season, and it is a little late in radeonn year.

The memory controller and memory bandwidth optimization techniques HyperZ were identical.

Com forum, November 11, 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. Unfortunately, unless product is available at launch, it makes it very hard for us to guess when we will see anything come along.

Although the Rbased chips are fundamentally similar to Rbased cores, ATI did tweak and ato the pixel shader units for more flexibility.


ATi Radeon R Series – Wikipedia

The stock thermal solution ATI provides is quite different from what we’ve seen in the past, and quite resembles the leaf-blower type systems we’ve seen attached to older GeForce FX based products. 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.

As all parties involved have had some practice with this part for a while, we would have been happier if ATI had gotten on the ball and had product on shelves today, if they do ship next week, they won’t be in bad shape.

HDCP is mandatory for the output of certain audio formats, placing additional constraints on the multimedia setup. The lower clocked, nm solution won’t be fitted with the leaf-blower, but a much smaller hsf.

Com, May 4, This magical fact is made possible through the wonders of process enhancements. Views Read Edit View history.

Generally, as the process gets better, yield improves, costs go down, and profits go up. With Radeeon 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.

The separation into “quads” also allowed ATI to design a system to optimize the efficiency of the overall chip.

Unfortunately, we couldn’t get ATI to go into any more detail on exactly what “substrate enhancements” were made, but shorter trace lengths translates to the possibility of higher stable memory clock speeds for ATI cards using the enhanced R chip. This article’s lead section may not adequately summarize its contents. There is absolutely no architectural difference between these new chips and the original R on which they are based.

ATI’s New Radeon X850 and X800 Lines: A Smorgasbord of GPUs

This new revision to PS2. Com, October 20, For a comparison point, here is an mp3 of the same testbed with an X XT starting up. In the case of the current generation of graphics cards, it took quite a while to go from launch to high availability. Support in this table refers to the most current version. R403 new pixel shader version PS2.

From Wikipedia, ayi free encyclopedia. This card usually came with a 3 quad configuration, like X GTO. 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.

It wasn’t available at launch, and we may never see it if the cards we look at today make it out the door. An X XT was planned for production, and reviewed by various d430 web sites, but was never released.
