Anti-aliasing was, for the first time, a fully usable option even in the newest and most demanding titles of the day. R was the first fully Direct3D 9-capable consumer graphics chip. It did cause a usually visibly imperceptible loss of quality when doing heavy blending. R; internal ArtX codename: Retrieved 7 December

Retrieved 23 March Later inthree new cards were launched: 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 was highly angle dependent.

Radeon was one of the shortest-lived product of ATI, later replaced ev280 the Radeon series. They were designed to maintain a performance lead over the recently launched GeForce FX Ultra, which it managed to do without difficulty. Besides advanced architecture, reviewers also took note of ATI’s change in strategy. A few months later, the and PRO were launched. Worthy of note regarding the Rbased generation is that the entire lineup utilized single-slot cooling solutions.

The architecture of R was quite different from its predecessor, Radeon Rin nearly every way. This trade-off in precision offered the best combination of transistor usage and image quality for the manufacturing process at the time. Radeon R Radeon R The textures can be any combination of one, two, or three dimensions with bilinearrv820or anisotropic filtering.


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.

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. A compatible HDCP display is also needed for this.

ATI Radeon 9250 (256 MB)

From Wikipedia, the free encyclopedia. ATI only intended for the series to be a temporary solution to fill the gap for the Christmas season, prior to the release of the Retrieved 7 December Equipped with 4 vertex shader rv28, 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.

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.

The logo and box package of the was resurrected in to market the unrelated and slower Radeon which is a derivative of the Current technologies and software. It also lost part of HyperZ III with the removal of the hierarchical z-buffer optimization unit, the same as Radeon 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.

Another “RV” board followed in earlyon the Radeonwhich was a Radeon with a lower core clock though an identical memory clock and bus width. During the summer ofthe Mobility Radeon was launched, based upon the RV core.


Support in this table refers to the most current version. Anti-aliasing was, for the first time, a fully usable option even in the newest and most demanding titles of the day. The R was the first board to truly take advantage of a bit memory bus.

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. R; internal ArtX codename: 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.

HDCP is mandatory for the output of certain audio formats, placing additional constraints on the multimedia setup.

Its texture units could perform a new loopback operation which allowed them to sample up to 16 textures per geometry pass.
