A compatible HDCP display is also needed for this. The R is the foundation for a line of DirectX 9. Its advantage over X is both lower power consumption and heat output. For example, the X uses 4 “quads”. Support in this table refers to the most current version.

Its advantage over X is both lower power consumption and heat output. This generation has support for all recent memory types, including GDDR4.

Radeon X1000 series

ATI opted to fit the cards with either MiB or MiB on-board memory foreseeing a future prp ever growing demands on local memory size. Retrieved from ” atti As is typical for an ATI video card release, a selection of real-time 3D demonstration programs were released at launch.

Like its predecessor X, the R chip carries 4 “quads” 4 pipelines eachwhich means it has similar texturing capability if at the same clock speed as its ancestor, and the NVIDIA series. Around the chip there are two bit ring buses running at the same speed as the DRAM chips, but in opposite directions to reduce latency. ATI has been working for years on a high-performance shader compiler in their driver for their older hardware, so staying with a similar basic design that is compatible offered obvious cost and time savings.

Again, the smaller cores such as RV and RV receive cutbacks due to ato smaller, less costly designs.


The demo showcased a highly complex environment, with high dynamic range lighting HDR and dynamic soft shadows. Views Read Edit View history. The X and X series fixes several flaws in the X design and adds a significant pixel shading performance boost. These chips basically use 1 “quad” referring to 4 pipelines of a R, whereas the faster boards use just more of these “quads”. Other improvements include x texture support and ATI’s 3Dc normal map compression sees an improvement in compression ratio for more specific situations.

Unfortunately, due to the programming content of available games, the X is greatly hampered by lack of texturing power. This refers to ATI’s plan to boost the efficiency of their GPU, instead of going with a brute force increase in the number of processing units. Current technologies and software. ATI Technologies products Video cards.

There is actually a fifth stop, one that is significantly less complex, designed for the PCI Express interface and video input. The primary change between R and R is that ATI changed the pixel shader processor to texture processor ratio.

Along these ring buses are 4 “stop” points where data exits the ring and going into or out of the memory chips. Ruby’s latest nemesis, Cyn, was composed ofpolygons. X was not behind schedule, and was always planned as the “spring refresh” chip. The R5xx family introduced a more advanced onboard motion-video engine. In other projects Wikimedia Commons. Retrieved 7 December From Wikipedia, the free encyclopedia. RV, for example, has two internal bit buses instead.


The X cards have 3 atii shaders on each pipeline instead of 1, giving a total of 48 pixel shader units.

Radeon X series – Wikipedia

This modular design allows ATI to build a “top to bottom” line-up using identical technology, saving research and development time and money. Because of its smaller design, these cards also offer lower power demands 30 wattsso they run cooler and can be used in smaller cases. A compatible HDCP display is also needed for this.

This means that RV has the same texturing ability as the X at the same clock speed, but with its 12 pixel shaders it encroaches on X’s territory in shader computational performance. See article on R’s pixel shaders. Contrasting the X however, R’s shader units are vastly improved. The Radeon X video cards, that included a R, were released with a delay of several months because ATI engineers discovered a bug within the GPU in a very late stage of the development.
