The fact that that registry key exists indicates that we did some experiments in the driver, not that we are half way done implementing pixel shaders on RADEON. These cards were produced until mid, when they were essentially replaced by the Radeon RV The R was built on a nm semiconductor manufacturing process. It basically improves the overall efficiency of the 3D rendering processes. Things get even more confusing once you take into account the different memory configurations available on Radeon based cards.

ATi Radeon R Series – Wikipedia

In 3D rendering the processor can write 2 pixels to the framebuffer and sample 3 texture maps per pixel per clock. Additionally, you have to understand that the phrase “shader” is an incredibly ambiguous graphics term.

Retrieved 7 December The performance difference was especially noticeable in bit colorwhere both the GeForce2 GTS and Voodoo 5 were far ahead. It also allowed the card to operate with asynchronous clock operation, whereas the original R was always clocked synchronously with the RAM. Log in Don’t have an account?

For years ATI has been considered to be a leader in multimedia or video features, courtesy of products like their TV tuner and All-in-Wonder lines, however they have rarely been considered to be the high-end performance leaders of the industry. Later drivers do not differentiate the Radeon LE from other Radeon R cards and the HyperZ hardware is enabled by default, though there may be visual anomalies on cards with HyperZ hardware that is defective.


The line features 3D acceleration based upon Direct3D 7. Post Your Svr Please log in or sign up to comment. Previewed in April of this year and released as well as shipped just two months later, the Radeon turned quite a few heads. ATI has definitely seen this opportunity, and just like AMD did following the introduction of their Athlon, ATI is attempting to take advantage of their situation as much as possible.

Basically, we hardware manufacturers started using the word “shader” a lot once we were able to do per-pixel dot products i. Recent reports have indicated that ATI was planning to dramatically phase out their Rage line and replace it with a more cost effective solution based on the Radeon core. Index The Chip HyperZ: Rbased GPUs raeon forward-looking programmable shading capability in their pipelines; however, the chips are not flexible enough to support the Microsoft Direct3D specification for Pixel Shader 1.

The Radeon launched in the second half of alongside xti Radeon R The Radeon’s Ark demo presents a science-fiction environment with heavy use of features such as multiple texture layers for image effects and detail. However, the Radeon could close the gap and occasionally outperform its fastest competitor, the GeForce2 GTS, in bit color. UVD 7 [7] 322mb. In terms of performance, Radeon scores lower than the GeForce2 in most benchmarks, even with HyperZ activated.

The R introduced HyperZan early culling technology maybe inspired by the Tile Rendering present in St Microelectronics PowerVR chips that became the way to go in graphic evolution and generation by generation rendering optimization, and can be considerend the first non tile rendering-based and so DX7 compatible card to use a Z-Buffer optimization.

Consisting of 3 different functions, it allows the Radeon to perform very competitively compared to competing designs with higher fillrates and bandwidth on paper. We mentioned earlier that the Radeon operates at up to MHz. HDCP is mandatory for the output of certain audio formats, placing additional constraints on the multimedia setup. ATI Technologies products Video cards. The introduction of the Rage Fury MAXX shortly thereafter gave ATI a strong taste of what competing in the high-end gaming market was like, and it only foreshadowed what was soon to come once ATI finally got a new core to work with.
