Socket , Socket However, refined design and manufacturing techniques enabled a doubling of transistor count and a significant clock speed gain. Archived from the original on In fall , a slightly faster variant, the Mobility Radeon was launched which was still based upon the RV, and not the older R of the desktop Radeon despite the naming similarity.

Its main advantage over the MX was that it had a full DirectX 8. See article on R’s pixel shaders. 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. 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 With a transistor count of million, it was the largest and most complex GPU of the time.

These were Rs with higher clock speeds, and improvements to the shader units and memory controller which enhanced anti-aliasing performance. To dampen excitement forcompetitor nVidia released their Detonator4 fadeon package on the same day as most web sites previewed the Radeon R has ATI’s first implementation of a hardware-accelerated tessellation engine a.

Anti-aliasing was, for the first time, a fully usable option even in the newest and most demanding titles of the day. 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. The architecture of R was quite different from its predecessor, Radeon Rin nearly every way. The phase instruction allows a shader program to operate on two separate “phases” 2 passes through the hardwareeffectively doubling the maximum number of texture addressing and arithmetic instructions, and potentially allowing the number of passes required for an effect to be reduced.


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.

The R, with its next-generation architecture giving it unprecedented features and performance, would have been superior to any R refresh. 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. 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. Current technologies and software. HDCP is mandatory for the output of certain audio formats, placing additional constraints on the multimedia setup.

Archived from the original on During the summer ofthe Mobility Radeon was launched, based upon the RV core. 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 For anisotropic filteringRadeon uses a technique similar to that used in R, but improved with trilinear filtering and some other refinements. 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.


The technology requires developer support and is not practical for all scenarios. R was the first fully Direct3D 9-capable consumer graphics chip. The “texcrd” instruction moves the texture coordinate values of a texture into the destination register, while the “texld” instruction will load the texture at the coordinates specified in the source register to the destination register.
