There are various rules that define the IGP’s processing capabilities. 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.
Support for Graphics Drivers for Intel® G45 Express Chipset
This version added support for automatic video mode detection and selection, monitor hot plug, dynamic extended and merged desktops and per-monitor screen rotation. Each pipeline can process video, vertex, or texture operations. The drivers were mainly garphics by Intel and Tungsten Graphics under contract since the chipsets’ documentation were not publicly available for a long time. This causes some difficulty when measuring peak throughput of its various functions.
However, due to the scalar nature of the execution units, they can only process data on a single pixel component at a time. The GMA X3x00’s unified shader design allows for more complete hardware functionality, but the line still has issues with some games and has significantly limited performance.
The available Linux drivers do not support much of this. This series targets the market of low-cost graphics solutions. Support is present in an experimental way for Nitel graphics found on Graphicx, Q35, G31 and G33 chipsets.
Archived from the original on August 11, It is based more directly on the previous generation GMA and GMA graphics, and belonging to the same “i” family with them.
Intel GMA – Wikipedia
However, with the introduction of Intel’s 4th generation of GMA architecture GMA X inmany of the functions are now built into the hardware, providing an increase in performance. The products in this series are integrated onto the inetl, have limited graphics processing power, and use the computer’s main memory for storage instead of a dedicated video memory.
It is supported by newer chipsets e. Archived from the original on July 31, In addition, hardware video acceleration such as hardware-based iDCT computation, ProcAmp video stream independent color correctionand VC-1 decoding are not implemented in hardware.
Features include screen tiling, internal true color processing, zero overhead anti-aliasing, programmable shader 3D accelerator, and bit floating-point operations. These features are built into the X.

Presumably this is due to the lack of a “hardware scheduler” in the GPU. Later, Intel integrated the i core into the Intel chipset.
No bit drivers were offered in OS X Lion. Archived from the original on November 26, Essentially, this is the same graphic system as the GMAbut clocked at double the speed.
Intel has released production version drivers for bit and bit Windows Vista that enable the Aero graphics. Drivers are shipped with Windows Vista since beta versions became available in mid In Novemberthe Linux Foundation released the details of inteo new, rewritten Linux driver that would support grapphics chipset and Intel’s other upcoming chipsets.
