Multi-sampling offered vastly superior performance over the supersampling method on older Radeons, and superior image quality compared to NVIDIA’s offerings at the time. The still held its own against the revised FX , primarily and significantly in tasks involving heavy SM2. See article on R’s pixel shaders. A few months later, the and PRO were launched. A slower chip, the , was launched a few months later, differing only by lower core and memory speeds.

While this differed from the older chips using 2 or 3 for the original Radeon texture units per pipeline, this did not mean R could not perform multi-texturing as efficiently as older chips.
However, refined design and manufacturing techniques enabled a ato of transistor count and a significant clock speed gain. The would be the second of ATI’s chips after the to be shipped to third-party manufacturers instead of ATI producing all of its graphics cards, though ATI would still produce cards off of its highest-end chips.
Radeon introduced ATI’s multi-sample gamma-corrected anti-aliasing scheme. This page was last edited on 31 Julyat Views Read Edit View history.

Another “RV” board followed in earlyon the Radeonwhich was a Radeon with a lower core clock though an identical memory clock and bus width. This was part of the new DirectX 9 specification, along with more flexible floating-point-based Shader Model 2. Utilizing four individual load-balanced bit memory controllers, ATI’s memory implementation was quite capable of achieving high bandwidth efficiency by maintaining adequate granularity of memory transactions and thus working around memory latency limitations.
See article on R’s pixel shaders. In earlythe cards were replaced by the or, R At the time, this was quite astonishing, and resulted in the widespread acceptance of AA and AF as critical, truly usable features. Alongside thethe a. The first graphics cards using the R to be released were the Radeon The demo was a real-time implementation of noted 3D graphics researcher Paul Debevec ‘s paper on the topic of high dynamic range rendering.
Khanlaunched in August The R was the first board to truly take advantage of 960le bit memory bus. Retrieved from ” https: Third time’s the charm?
R and its derivatives would form the basis for ATI’s consumer and professional product lines for over 3 years. ATI, however, had not only doubled their bus to bit, but also integrated an advanced crossbar memory controller, somewhat similar to NVIDIA ‘s memory technology. In falla slightly faster variant, the Mobility Radeon was launched which was still based upon the RV, and not the older R of the desktop Radeon despite the naming similarity.
One major change with the manufacturing of the core was the use of the flip-chip packaginga technology not used previously on video cards. ATI, perhaps mindful of what had happened to 3dfx when they took focus off their Rampage processor, abandoned it in favor of finishing off their next-generation R card.
These were Rs with higher clock speeds, and improvements to the shader units and memory controller which enhanced anti-aliasing performance. This trade-off in precision offered the best combination of transistor usage and image quality for the manufacturing process at the time.

A slower chip, thewas launched a few months later, differing only by lower core and memory speeds. Its texture units could perform a new loopback operation which allowed them to sample up to 16 textures per geometry pass. Retrieved 23 March The performance and quality increases offered by the R GPU is considered to be one of the greatest in the history of 3D graphics, alongside the achievements GeForce and Voodoo Graphics.
R would become one of the GPUs with the longest useful lifetime in history, allowing playable performance in new games at least 3 years after its launch. This freed up engineering resources that were channeled towards driver improvementsand the performed phenomenally well at launch because of this.
