AMD confirmed to TechPowerUp its plans of removing pre-HD 5000 series Radeon GPUs from the Catalyst mainline update model (where WHQL-certified driver updates are released on a monthly basis), but that doesn't necessarily mean a discontinuation of support for those products. AMD told us that it is merely relocating pre-HD 5000 GPUs (under the Radeon HD 2000, HD 3000, and HD 4000 series), to a new update model that will have new WHQL-certified drivers being released on a quarterly basis. This model is carved out of the mainline, because the driver team is encountering a diminishing number of problems that can be addressed, with the older chips, and can pool them up over a quarter and release updates for them. The driver team can then focus on Radeon HD 5000 (and later) product lines. AMD also talked about the current lack of driver support for pre-HD 5000 GPUs on Windows 8 consumer preview. It said that the driver that Microsoft ships with Windows 8 will support for pre-HD 5000 GPUs, and of course in the future AMD will have WHQL-certified Windows 8 drivers for these chips, part of its new update model. A variant of the driver version 8.97, released in May, will be the first pre-HD 5000 driver in this new update model. A transcript of AMD's statement follows.
