The RadeonHD driver software is an OS 4.x 2D graphics driver for RadeonHD graphics card. It also supports some Radeon Rx models.

The RadeonHD driver version up to V3 supports the RadeonHD 2000-7000 series cards (and the older Radeon X1300-X1950). From Version 5, the RadeonHD driver only supports Southern Islands chipsets such as the RadeonHD 7770, R7-240 and R7-250.

There are five versions of the RadeonHD driver commercially released:

End Of Line Versions

  • RadeonHD Lite
  • RadeonHD v1 (including pre v1)
  • RadeonHD v2

Current Versions

  • RadeonHD v3
  • RadeonHD v5 - only supports Southern Islands chipsets

Lite version is supplied as an OEM driver under agreement to third parties. This version is intended for emergency boot and installation of the AmigaOS4.1 Final Edition CD and therefore is limited to 800x600 pixel screen resolution and compositing is not possible. It does not contain any SPE-FPU optimisations and it does not support 64-bit VRAM.

Version 1 is supplied as part of the Standard Edition of the Enhancer Software package. It is end of line with no further development planned.

Version 2 is supplied as part of the Plus Edition of the Enhancer Software package. It is end of line with no further development planned.

Version 3 is supplied as part of the Graphics Upgrade add-on for the Enhancer Software package and Enhancer Software Release 2.
