ATI Radeon X series

The logo of the X850

The Radeon X series is a series of desktop graphics chips from ATI Technologies and was released in 2004 and 2005 as the successor to the Radeon 9000 series . It is the fourth generation of graphics processors with the name ATI Radeon . It was replaced by the Radeon X1000 series . The main competitor was the Nvidia GeForce 6 series .

Graphics processors

Quads

The graphics chips used consist of so-called "quads". This mainly indicates the number of rendering pipelines used and the associated pixel shaders , but the number of VPUs also depends on it. The number of rendering pipelines and pixel shaders increases by four for each quad, and the number of VPUs is increased by two for each quad.

Graphics processors

Various graphics processors are used within the Radeon X series, which differ in terms of production technology and 3D capabilities. In contrast to its competing series from Nvidia , the X series from ATI does not yet have a pixel shader 3.0 that can be used for new effects. Fewer effects are possible with Pixelshader 2.0b. Most of the graphics processors in the Radeon X series were developed for PCI Express , but these graphics processors can also be connected to AGP using the Rialto chip from ATI .

Naming

ATI Radeon X850XT Platinum Edition

ATI X700

All graphics chips are labeled with a three-digit number that generally begins with an "X", the Roman numeral for 10. The first digit divides the family into different market segments. The second and third digits serve for further diversification. These models are subdivided into different variants, which are identified with a corresponding abbreviation after the model number. Overall, this leads to a very large variety of model names.

division

• X3xx / X5xx: low-cost
• X6xx / X7xx: mainstream
• X8xx: high-end

Letter abbreviations

• CF  - Crossfire master card
• SE  - attenuated standard version, the slowest model of a segment
• LE  - slightly weakened standard version
• GT  - budget version of a chip with disabled quads, slower than the "standard" version
• [no suffix]  - "Standard" version
• Pro  - budget version of a chip, more powerful than the “standard” version
• GTO  - chip in the high-end segment, one quad deactivated, less powerful XL version
• XL  - More powerful chip in the high-end segment, all quads are activated, but a little less powerful than the XT version
• XT  - More powerful chip in all segments, all quads are activated
• XT PE (PE: Platinum Edition) - The most powerful single-core chip in the high-end segment

Other abbreviations such as "RX", "GTO ² ", "XXL", "Ultimate", "Silentpipe" or "Performance Edition" are not official names from ATI, but marketing names of individual graphics card manufacturers that are intended to indicate special properties.

Hints

• The stated clock rates are those recommended or specified by AMD. However, the final specification of the clock rates is in the hands of the respective graphics card manufacturer. It is therefore entirely possible that there are or will be graphics card models that have different clock rates.
• It is also up to the manufacturers whether the final graphics card has a PCIe or an AGP connection, because GPUs with a native PCIe interface can also be used for AGP graphics cards with the help of a bridge chip.
• The table above does not include ATI all-in-wonder graphics cards with Radeon chips (AIW). Despite the partly identical naming (apart from the “all-in-wonder” instead of Radeon), other chips are sometimes used.
