R400 Series

The Radeon X series is a series of desktop graphics chips brand ATI Technologies, and was published in 2004 and 2005 as a successor to the Radeon 9000 series. This makes it the fourth-generation GPUs with the name ATI Radeon. It was replaced by the Radeon X1000 series. Main competitor was the Nvidia GeForce 6 series.

GPUs

Quads

The graphics chips used consist of so-called " quads ". Thus the number of rendering pipelines used and the associated pixel shader is mainly characterized, but also the number of VPUs depends. Pro Quad increased the number of rendering pipelines and the pixel shader to four, from the third quad, the number of VPU is increased by two.

GPUs

Within the Radeon X series different GPUs are used, which differ in terms of manufacturing technology and the 3D capabilities. Unlike their competition series from Nvidia, the X - series from ATI still dominates no Pixel Shader 3.0, which can be used for new effects. With Pixel Shader 2.0b less effects are possible. Much of the graphics processors of Radeon X Series was designed for PCI - Express, using the Rialto chips from ATI GPUs can this be, however, also be linked to AGP.

Naming

All graphics chips are identified by a three-digit number, which generally begin with an "X ", that is the Roman numeral for 10. The first digit divides the family into different market segments. The second and third digits are used to further diversification. These models are categorized into different variants that are marked with an appropriate symbol behind the model number. This leads to a very large variety of model names in total.

Distribution:

  • X3xx / x5xx: low-cost
  • X6xx / x7xx: Mainstream
  • X8xx: High- End

Abbreviation:

  • CF - Crossfire master card
  • SE - attenuated standard version, the slowest model of a segment
  • LE - slightly weaker 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 efficient than the "standard" version
  • GTO - disabled chip in the high-end segment, a quad, less powerful XL version
  • XL - More powerful chip in the high-end segment, all quads are activated, but something 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 Einkernchip in the high-end segment

Other prefixes such as "RX ", " GTO2 ", " XXL ", " Ultimate ", " Silentpipe " or " Performance Edition " are not official designations from ATI, but marketing names of individual graphics card manufacturer, which is to be subject to special properties.

Model data

Notes:

  • The specified clock rates are the recommended or imposed by AMD. However, is the final determination of the clock rates in the hands of the respective graphics cards manufacturers. Therefore, it is quite possible that there are graphics cards models or will be having different clock speeds.
  • Also, it is the responsibility of manufacturers, whether or not the final graphics card has a PCIe or AGP connector, because GPUs with native PCIe interface can be used by means of a bridge chip for AGP graphics cards.
  • The above table does not include ATI All- in-Wonder video cards with Radeon chips ( AIW ). Despite partially homonymous names (except for the " All- in-Wonder " instead Radeon ) other chips are partially used.
