The combination of these two changes in graphics driver code resulted in many Mac revisions being unable to upgrade to Mountain Lion, as their GPUs cannot be replaced. Subsequently, OS X Mountain Lion dropped 32-bit kernel booting. No 64-bit drivers were offered in OS X Lion. Intel used the low-power designs in chipsets supporting their platform, and since the sale of XScale in 2006 has licensed the and used it in the IGP for use with their platform.Īpple removed the 64-bit GMA X3100 drivers later, and thus affected Macs were forced back to the 32-bit kernel despite being 64-bit clean in terms of hardware and firmware. Despite similarities, Intel's main series of GMA Integrated Graphics Processors (IGPs) is not based on the technology Intel licensed from Imagination Technologies. While GMA performance has been widely criticized in the past as being too slow for, sometimes being nicknamed Intel GMD (Graphics Media Decelerator) and being essentially referred to as the world's first 'graphics decelerator' since the, the latest GMA generation should ease many of those concerns for the casual gamer. Many of the advantages of the new GMA architecture come from the ability to flexibly switch as needed between executing graphics-related tasks or video-related tasks. The 4th generation of GMA combines fixed function capabilities with a threaded array of programmable executions units, providing advantages to both graphics and video performance.
