Official ATI specifications dictate a bit memory bus for the SE, but most of the manufacturers used a bit bus. R was the first fully Direct3D 9-capable consumer graphics chip. Worthy of note regarding the Rbased generation is that the entire lineup utilized single-slot cooling solutions.
The processors also include 2D GUI accelerationvideo acceleration, and multiple display outputs. One major change with the manufacturing of the core was the use of the flip-chip packaginga technology not used previously on video cards.

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 R Radeon R The logo and box package of the was resurrected in to market the unrelated and slower Radeon which is a derivative of the The R was the first board to truly take advantage of a bit memory bus. Its texture units could perform a new loopback operation which allowed them to sample up to 16 textures per geometry pass.
During the summer ofthe Mobility Radeon was launched, based upon the RV core. Flip chip packaging allows far better cooling of the die by flipping it and exposing it directly to the cooling solution.

Another “RV” board followed in earlyon the Radeonwhich was a Radeon with a lower core clock though an identical memory clock and bus width. R; internal ArtX codename: Another selling point for the was that it was still a single-slot card, compared to the dual-slot requirements of the FX and FX Since all of the R chips were based on the same physical die, ATI’s margins on products were low.
Matrox had released their Parhelia several months earlier, but this board did not show great gains with its bit bus.
A few months later, the and PRO were launched. It also lost part of HyperZ III with the removal of the hierarchical z-buffer optimization unit, the same as Radeon sappuire Third time’s the charm?

The demands of the 8×1 architecture required more bandwidth than the bit bus designs of the previous generation due to having double the texture and pixel fillrate.
The demo was a real-time implementation of noted 3D graphics researcher Paul Debevec ‘s paper on the topic of high dynamic range rendering. This page was last edited on 31 Julyat They were designed to maintain a performance lead over the recently launched GeForce FX Ultra, which it managed to do without difficulty.
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. 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.

However, refined design and manufacturing techniques enabled a doubling of transistor count and a significant clock speed gain. Equipped with 4 vertex shader units, R possessed over twice the geometry processing capability of the preceding Radeon and the GeForce4 Tiin addition to the greater feature-set offered compared to DirectX 8 shaders.
The R, with its next-generation architecture giving it unprecedented features and performance, would have been superior to any R refresh. R would become one of the GPUs with the longest useful lifetime in history, allowing playable performance in new atlabtis at least 3 years after its launch. The other two variants were thewhich was simply a lower-clocked Pro, and the SE, which had half the pixel processing units disabled could sometimes be enabled again.
Current technologies and software. The R also offered advanced anisotropic filtering which incurred a much smaller performance hit than the anisotropic solution of the GeForce4 and other competitors’ cards, while offering significantly improved quality over Radeon ‘s anisotropic filtering implementation which radeob highly angle dependent. Radeon was one of the shortest-lived product of ATI, later replaced by the Radeon series.
