During the summer of , the Mobility Radeon was launched, based upon the RV core. ATI Technologies products Video cards. Anti-aliasing was, for the first time, a fully usable option even in the newest and most demanding titles of the day. The R, with its next-generation architecture giving it unprecedented features and performance, would have been superior to any R refresh. 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 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. Current technologies and software. At the time, this was 9600xe astonishing, and resulted in the widespread acceptance of AA and AF as critical, truly usable features. Since all of the R chips were based on the same physical die, ATI’s margins on products were low.

R was the first fully Direct3D 9-capable consumer graphics chip. With rsdeon transistor count of million, it was the largest and most complex GPU of the time. Its texture units could perform a new loopback 9600sr which allowed them to sample up to 16 textures per geometry pass.

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 was part of the new DirectX 9 specification, along with more flexible floating-point-based Shader Model 2. A compatible HDCP display is also needed for this. UVD 7 [1] [d].

The radfon 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. The R was the first board to truly take advantage of a bit memory bus.

During the summer ofthe Mobility Radeon was launched, based upon the RV core. 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.

It also lost part of HyperZ III with the removal of the hierarchical z-buffer optimization unit, the same as Radeon Besides advanced architecture, reviewers also took note of ATI’s change in strategy.

The chip adopted an architecture consisting of 8 pixel pipelines, each with 1 texture mapping unit an 8×1 design. A few months later, the and PRO were launched.

The would be the second of ATI’s chips after the to be shipped 9600sse third-party manufacturers instead of ATI producing all of its graphics cards, though ATI would still produce cards off of its highest-end chips.

ATI demonstrated part of what was capable with pixel 9060se PS2. 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.


Radeon ‘s advanced architecture was very efficient and, of course, more powerful compared to its older peers of The architecture of R was quite different from its predecessor, Radeon Rin nearly every way. Worthy of note regarding the Rbased generation is that the entire lineup utilized single-slot cooling solutions.

The textures can be any combination of one, two, or three dimensions with bilineartrilinearor anisotropic raeon. In earlythe cards were replaced by the or, R Retrieved 23 March This trade-off in precision offered the best combination of transistor usage and image quality for the manufacturing process at the time. Views Read Edit View history. Matrox had released their Parhelia several months earlier, but this board did not show great gains with its bit bus.


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 HDCP is mandatory for the output of certain audio formats, placing additional constraints on the multimedia setup. In falla slightly faster variant, the Radeonn Radeon was launched which was still based upon the RV, and not the older R of the desktop Radeon despite the naming similarity.
