With chips such as RV and R, where the number of shader units per pipeline triples, the efficiency of pixel shading drops off slightly because these shaders still have the same level of threading resources as the less endowed RV and R A compatible HDCP display is also needed for this. When one of the shader quads becomes idle, due to a completion of a task or waiting for other data, the dispatch engine will assign the quad with another task to do in the meantime, with the overall result being a greater utilization of the shader units, theoretically. In other projects Wikimedia Commons. The X was based on the R core and was sold as an ultra-low-budget part. Get quality that rivals up to 4K even on a p display. Using a Linux distribution a series of open source Radeon drivers are available.

Raseon X and X series fixes several flaws in the X design and adds a significant pixel shading performance boost. With chips such as RV and R, where the number of shader units per pipeline triples, the efficiency of pixel shading drops radeoon slightly because these shaders still have the same level of threading resources as the less endowed RV and R R and R had nearly identical memory controller designs, with the former being a bug fixed release designed for higher clock speeds.

From Great to Greatness Artfully Designed. The chip’s single “quad” has 3 pixel shader processors per pipeline, similar to the design of R’s 4 raseon. Not only are they fully Shader Model 3 capable, but ATI introduced some innovative advancements in shader threading that can greatly improve the efficiency of the shader units.


The Radeon X series using the core was introduced on October 5,and competed primarily against nVidia’s GeForce series. By using this site, you agree to the Terms of Use and Privacy Policy. RV, for example, has two internal bit buses instead. Retrieved from ” https: Taking your game ardeon a whole new level.

All scores in average FPS and are an average of 3 runs with the same settings. ATI opted to fit the cards with either MiB or MiB on-board memory foreseeing a future of ever growing demands on local memory size. This means you can focus on gaming without the noise of spinning fans.

Last AMD Catalyst version that officially supports this series, is Frame Rate Target Control. The X cards have 3 pixel shaders on each pipeline instead of 1, giving a total of 48 pixel shader units. Offering powerful OS compatibility, rendering features, and hardware efficiency. 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.

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. ATI has taken this step with the expectation that future 3D software will be more pixel shader intensive. This design allows memory accesses to be far quicker though lower latency by virtue of the smaller distance the signals need to move through the GPU, and by increasing the number of banks per DRAM.


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.
