These were very popular for Dell and other OEM companies to sell in various configurations; connectors: ATI had held the lead for a while with the Radeon but Nvidia retook the performance crown with the launch of the GeForce 4 Ti line. A few months later, the and PRO were launched. These were Rs with higher clock speeds, and improvements to the shader units and memory controller which enhanced anti-aliasing performance. A slower chip, the , was launched a few months later, differing only by lower core and memory speeds. 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. They were nearly identical to the chips used in Radeon and , only differing in that they were native PCI Express offerings.

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 A few months later, the and PRO were launched. However, refined design and manufacturing techniques enabled a doubling of transistor count and a significant clock speed gain.

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 Retrieved from ” https: The processors also include 2D GUI accelerationvideo acceleration, and multiple display outputs. This page was last edited on 15 Marchat The first graphics cards using the R to be released were the Radeon Since all of the R chips were based on the same physical die, ATI’s margins on products were low.


The textures can be any combination of one, two, or three dimensions with bilineartrilinearor anisotropic filtering. ATI demonstrated part of what was capable with pixel shader PS2.

ATI thus could achieve higher clock speeds. The R, with its next-generation architecture giving it unprecedented features and performance, would have been superior to any R refresh. In other projects Wikimedia Commons.

Equipped with 4 vertex shader units, R possessed over twice the geometry processing capability of the preceding Radeon and the GeForce4 Tiin addition atk the greater feature-set offered compared to DirectX 8 shaders. R and its derivatives would form the basis for ATI’s consumer and professional product lines for over 3 years. ATI had held the lead for a while with the Radeon but Nvidia retook the performance crown with the launch of the GeForce 4 Ti line. This freed up engineering resources that were channeled towards driver improvementsand the performed phenomenally well at launch because of 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. 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. 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.

Besides advanced architecture, reviewers also took note of ATI’s change in strategy. Official ATI specifications dictate a bit memory bus for the SE, but most of the manufacturers used a bit bus. At the time, this was quite special, and resulted in the widespread acceptance of AA and AF at truly usable features.

The performance and quality increases offered by the R GPU are considered to be one of the greatest in the history of 3D graphics, alongside the achievements GeForce and Voodoo Graphics. at

ATi Radeon R Series – Wikipedia

The integrated graphics processor based upon R is the Xpress Being the first laptop chip to offer DirectX 9. Khanlaunched in August The R was the first board to truly take advantage of a bit memory bus. ATI, however, had not only doubled their bus to wti, but also integrated an advanced crossbar memory controller, somewhat similar to NVIDIA ‘s memory technology. Its texture units could perform a new loopback operation which allowed them to sample up to 16 textures per geometry pass.

For other uses, see R disambiguation. ATI, perhaps 95500 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. It did cause a usually visibly imperceptible loss of quality when doing heavy blending. The still held its own against the revised FXprimarily and significantly in tasks involving heavy SM2.
