had a full DirectX 8.1 vertex and pixel shader implementation. While the 9000 was not quite as fast as the 8500LE or the Nvidia GeForce3 Ti200, the 8500LE and Ti200 were to be discontinued, though the former was reintroduced due to strong market demand. Radeon 9200 A later revision of the 9000 was the Radeon 9200 (RV280) released April 16, 2003, which aside from supporting AGP 8X, was identical. There was also a cheaper version, the 9200SE, which had a 20% lower clock speed and only had a 64-bit memory bus. Another board, called the Radeon 9250 was launched in July 2004, being simply a slightly lower-clocked RV280. ATI had re-branded its products in 2001, intending the 7xxx series to indicate DirectX 7.0 capabilities, 8xxx for DirectX 8.1, and so on. However, in naming the Radeon 9000/9200, which only had DirectX 8.1 rendering features, ATI advertised them as "DirectX 9.0 compatible" while the truly DirectX 9.0-spec Radeon 9700 was "DirectX 9.0 compliant". Laptop versions The Mobility Radeon 9000 was launched in early summer 2002 and was the first DirectX 8 laptop chip. It outperformed the DirectX 7-based nVidia GeForce 2 Go and was more feature-rich than the GeForce 4 Go. A Mobility Radeon 9200 later followed as well, derived from the desktop 9200. The Mobility Radeon 9200 was also used in many Apple laptops, including the Apple iBook G4. Models Drivers Unix-related operating systems The open source drivers from X.org/Mesa support almost all features provided by the R200 hardware. They are shipped by default on most BSDs and Linux systems. Newer ATI Catalyst drivers do not offer support for any R500 or older architecture product. The PowerPC-based Mac mini and iBook G4, which run on Mac OS X, were supplied with Radeon 9200 GPUs; the final Power Mac G4 "Mirrored Drive Door" systems had the 9000 and 9000 Pro cards available as a BTO option. Windows drivers This series of Radeon graphics cards is supported by AMD under Microsoft Windows operating systems including Windows XP (except x64), Windows 2000, Windows Me, and Windows 98. Other operating systems may have support in the form of a generic driver that lacks complete support for the hardware. Driver development for the R200 line ended with the Catalyst 6.11 drivers for Windows XP. Classic Mac OS The Radeon 9250 was the final ATI card to officially support Mac OS 9. AmigaOS The R200 series
