The X Pro is the first ATI card that supports native Crossfire implementation by a pair of internal Crossfire connectors, which eliminates the need for the unwieldy external dongle found in older Crossfire systems. RV, for example, has two internal bit buses instead. 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. 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.

Ruby’s latest nemesis, Cyn, was composed ofpolygons. The R5xx family introduced a more advanced onboard motion-video engine.

Unlike the X, the X has 16 pixel shader processors as well, and equal ratio of texturing to pixel shading capability. The R is the foundation for a line of DirectX 9. 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. R, however, differs with its central controller arbiter that connects to the “memory clients”.

Current technologies and software. The card was launched on August 23, In addition to ring bus, each memory channel now has the granularity pdo bits, which improves memory efficiency when performing small memory requests.

This means that RV has the same texturing ability as the X at the same clock speed, pdo with its 12 pixel shaders it encroaches on X’s territory in shader computational performance. ATI Technologies products Video cards.

The problem had been almost random in how it affected the prototype chips, making it quite difficult to finally identify. X was not behind schedule, and was always planned as the “spring refresh” chip. The Radeon X series using the core was introduced on October 5,and competed primarily against nVidia’s GeForce series.

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.

This generation has support for all recent memory types, including GDDR4. The RV has a 3: UVD 7 [18] [d].

Basically the chip can spread out memory requests faster and more directly to the RAM chips. As is typical for an ATI video card release, a selection of real-time 3D demonstration programs were released at peo.

The X series has two parts, which are quite different with regards to performance. The X Pro is the first ATI card that supports native Crossfire implementation by a pair of internal Crossfire connectors, which eliminates the need for the unwieldy external dongle found in older Crossfire systems.

Along these ring buses are 4 “stop” points where data exits the ring and going into or out of the memory chips. See article on R’s pixel shaders. The primary change between R and R is that ATI changed the pixel shader processor to texture processor ratio. There is actually a fifth stop, one that is significantly less complex, designed for the PCI Express interface and video input. The X was based on the R core and was sold as an ultra-low-budget part.

Archived from the original 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.

It also gains three extra vertex shaders, bringing the total to pto units.

Contrasting the X however, R’s shader units are vastly improved. The demo showcased a highly complex environment, with high dynamic range lighting HDR and dynamic soft shadows. 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. 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 Last AMD Catalyst version that officially supports this series, is
