With the Radeon 8500, ATI integrated an addition Rage Theater chip, which reduces production costs and enables a simpler board design. The Radeon 9000, like the Radeon 75, is a highly integrated chip that has two 400 MHz RAMDACs as well as complete circuitry necessary for TV-out. However, it still remains to be seen how this solution works in practice. This step lets ATI save on transistors, which, in turn, has a positive effect on the price.

With simple driver updates, optimizations for new video formats can be implemented. In addition, there are completely new realtime filtering capabilities available that, for example, prevent pixelation in low-resolution videos or allow special optimizations for specific video codecs such as DivX. During video playback, the pixel shaders remain in 2D mode anyway, so they are available for this purpose.

This allows ATI to combine the optimized calculations in the hardware and the flexibility of a software solution, in the form of special pixel shader programs. As with the R300, ATI does away completely with the circuitry responsible for this and instead uses a new technology called 'Videoshader'. Graphics cards from ATI have the reputation of providing high quality DVD and video playback, and with good reason. The third and final big change affects the video capabilities. If the Canadian PR department is to be believed, then the new vertex shaders contain many optimizations that are also found in the R300 design. With the R9000, these units were re-worked and optimized. The R8500 had two shader units more than NVIDIA's GeForce3. The reason for keeping quiet on this was more because of marketing concerns rather than understatement. It wasn't till now that ATI has admitted that the Radeon 8500 contains two vertex shader units, similar to the GeForce4 Ti. The second change has to do with the vertex shader. What these confusing numbers mean in practice is that the R9000 is considerably slower than the R8500 in games with multitexturing. In exchange, the number of textures that comprise the end pixel increases from three to six. Instead of two pixels per cycle, however, these can only calculate 1 texel per cycle. Just as with the R8500, the R9000 has four pixel pipelines. The more significant changes have to do with the pixel pipeline.

After all, with the OEM and mainstream markets, every penny counts. Fewer transistors enable a larger yield, thereby resulting in lower production costs and consequently a lower price. Aside from performance aspects, these changes are supposed to allow for cost reductions. Moreover, significant modifications were made to the 3D core. As with its predecessor, the Radeon 7500, ATI has once again integrated the functions of the Rage Theater chip and integrated a second RAMDAC in the chip. If you thought that the Radeon 9000 (alias RV250) would merely be a simplified version of the Radeon 8500 (R200), then you're quite mistaken.

Even SiS, the newcomer to the 3D arena, offers pixel shader support with its new Xabre card! Vertex shader programs can only be run with GeForce4 MX with the help of optimized software emulation in the NVIDIA driver. NVIDIA'S mainstream product, GeForce4 MX, is still a pure DirectX 7 design stemming from the somewhat outdated GeForce2. This gives ATI a jump ahead of its San Jose-base competitor in the lower price segment ($100-$150), because it brings the first real DirectX 8 card on the market. Generally speaking the new Radeon 9000 chip is based on the Radeon 8500 design and has a vertex shading unit (v1.0) as well as a pixel shader unit (v1.4).
