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. However, refined design and manufacturing techniques enabled a doubling of transistor count and a significant clock speed gain. Retrieved 7 December A compatible HDCP display is also needed for this. 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. 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. They were designed to rdeon a performance lead over the recently launched GeForce FX Ultra, which it managed to do without difficulty.

See article on R’s pixel shaders. ATI demonstrated part of what was capable 980 pixel shader PS2. With a transistor count of million, it was the largest and most complex GPU of the time.

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. Matrox had released their Parhelia several months earlier, but this board did not show great gains with its bit bus.

Worthy of note regarding the Rbased generation is that the entire lineup utilized single-slot cooling solutions. Official ATI specifications dictate a bit memory bus for the SE, but most of the manufacturers used a bit bus. 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.


A compatible HDCP display is also needed for atj. This freed up engineering resources that were channeled towards driver improvementsand the performed phenomenally well at launch because of this. UVD 7 [1] [d]. The still held its own against the revised FXprimarily and significantly in tasks involving heavy SM2.

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.

This trade-off in precision offered the best combination of transistor usage and image quality for the manufacturing process at the time. 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 Alongside thethe a.

Anti-aliasing was, for the first time, a fully usable option even in the newest and most demanding titles of the day. 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 first graphics cards using the R to be released were the Radeon These were Rs with higher clock speeds, and improvements to the shader units and memory controller which enhanced anti-aliasing performance.


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

Radeon 9000 Series

Support in this table refers to the most current version. Being the first laptop chip to offer DirectX 9. The chip adopted an architecture consisting of 8 pixel pipelines, each with 1 texture mapping unit an 8×1 design.

Radeon was one of the shortest-lived product of ATI, later replaced by the Radeon series.

The R was the first board to truly take advantage of a bit memory bus. The architecture of R was quite different from its predecessor, Radeon Rin nearly every way. ATI, however, had not only radeob their bus to bit, but also integrated an advanced crossbar memory controller, somewhat similar to NVIDIA ‘s memory technology.

Retrieved 7 December dr 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.
