Ok, well if that is your card, then go to the site I showed the link to, enter your pc details, and download and install the driver. ATI Technologies products Video cards. Because of its smaller design, these cards also offer lower power demands 30 watts , so they run cooler and can be used in smaller cases. UVD 7 [18] [d]. Last AMD Catalyst version that officially supports this series, is

It also gains three extra vertex shaders, bringing the total to at units. 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. TechSpot Account Sign up for freeit takes 30 seconds. The next major change to the core is with its memory bus.

Contrasting the X however, R’s shader units are vastly improved.

ATI Catalyst Radeon X1300/X1550 series

ATI Technologies products Video cards. The card was launched on August 23, The problem had been almost random in how it affected the prototype chips, making it quite difficult to finally identify. For example, the X uses 4 “quads”. The primary change between R and R is that ATI changed the pixel shader processor to texture processor ratio. This series is the s1550 solution of the X series and is based on the RV core.

Radeon X series – Wikipedia

The X xx1550 X series fixes several flaws in the X design and adds a significant pixel shading performance boost. 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.

Archived from the zti on May 7, 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.

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. With chips such as RV and R, where the number of shader units wti 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 ATI has been working for years on a high-performance shader x150 in their driver for their older hardware, so staying with a similar basic design that is compatible offered obvious cost and time savings.

The X series has two parts, which are quite different with regards to performance. Again, the smaller cores such as RV and RV receive cutbacks due to their smaller, less costly designs.


Last AMD Catalyst version that officially supports this series, is Your name or email address: R, however, differs with its central controller arbiter that connects to the “memory clients”. Unfortunately, due to the programming content of available games, the X is greatly hampered by lack of texturing power.

TechSpot is dedicated to computer enthusiasts and power users. The R is the foundation for a line of DirectX 9. Retrieved 23 March With such a large number of threads per “quad”, ATI created a very large general purpose register array that is capable of multiple concurrent reads and writes and has a high-bandwidth connection to each shader array.

The chip’s single “quad” has 3 pixel shader processors per pipeline, similar to the design of R’s 4 quads. Its advantage over X is both lower power consumption and heat output. Atl generation has support for all recent memory types, including GDDR4.
