The Mobile Intel GM45, Intel GS45, and Intel GL40 Express chipsets provide flexibility for developers of embedded applications by offering graphics, memory, and I/O bandwidth, as well as remote asset management capabilities, storage speed and reliability. Features include an improved integrated graphics engine, up to 1066 MHz front-side bus (FSB), DDR2 or DDR3 system memory controller, and support for Intel Active Management Technology (Intel AMT), Intel Trusted Execution Technology (Intel TXT), and Intel Matrix Storage Technology. The Mobile Intel GS45 Express chipset provides the same feature set and functionality as the Mobile Intel GM45 Express chipset but in a smaller package (22mm x 22mm). The Mobile GL40 Express chipset has a subset of features available on the Mobile Intel GM45 Express chipset, and when paired with Intel Celeron processors, is suitable for value-oriented applications.

These chipsets address requirements of embedded applications such as interactive clients, gaming platforms and industrial automation equipment. They consist of the Intel GM45/GS45/GL40 Graphics Memory Controller Hub (GMCH), and the Intel I/O Controller Hub 9M (ICH9M), available in three SKUs. The ICH9M supports system performance through high-bandwidth interfaces including PCI Express, Serial ATA, and USB 2.0.

The chipsets are optimized for the following processors: Intel Core2 Duo processor T9400 at 2.53 GHz with 35 watts thermal design power (TDP) [GM45]; Intel Core2 Duo processor SL9400 at 1.86 GHz with 17 watts TDP [GS45]; Intel Core2 Duo processor SP9300 at 2.26 GHz with 25 watts TDP [GS45]; Intel Celeron M processor 722 at 1.2 GHz with 5.5 watts TDP [GS45]; and the Intel Celeron processor 575 at 2.0 GHz with 31 watts TDP [GL40/GM45].

The Dual-channel memory controller supports non-ECC, 667/800 MHz DDR2 or 800/1066 MHz DDR3 SO-DIMM SDRAM (no DDR3 memory support in GL40). The Mobile Intel Graphics Media Accelerator 4500MHD, Intel Clear Video Technology, and graphics core speeds up to 533 MHz improve graphics and 3D rendering performance, and enable high-definition video playback. It supports display/video output options such as VGA, LVDS, DVI, High Definition Multimedia Interface (HDMI) and DisplayPort with integrated High-bandwidth Digital Copy Protection (HDCP) technology. Dual independent display support allows for flexible display configurations. The x16 PCI Express graphics or a dual-channel Serial Digital Video Output (SDVO) graphics interface supports high throughput for high-end graphics (not available in GL40). The Direct Media Interface chip interconnect between the GMCH and the ICH can be implemented at x4 or x2 widths, providing up to 1 GB/s in each direction in full duplex.

The 12 USB 2.0 ports may be controlled by up to two high-speed Enhanced Host Controller Interfaces (EHCI) or up to six Universal Host Controller Interfaces. Each EHCI allows data transfers of up to 480 Mb/s. Up to six PCI Express root ports on the ICH are configurable as six single x1 ports or partially ganged together as one x4 port and two x1 ports. Each root port allows transfer rates of up to 2.5 GB/s in each direction.

Two integrated Serial ATA host controllers, each with transfer rates of up to 3 Gb/s, support four SATA ports. The Intel Matrix Storage Technology provides both AHCI and RAID functionality for improved storage speed and data redundancy (ICH9M-Enhanced SKU only; not available in GL40). Intel AMT, when used with the Intel WG82567LM Gigabit Ethernet Controller, supports asset management capabilities such as remote management of unmanned sites (ICH9M-Enhanced SKU only; not available in GL40). Intel TXT provides hardware-based mechanisms to help defend against software-based attacks and protect the confidentiality and integrity of data stored or created on the system. Intel TXT enables each application to run within its own space, protected from all other software on the system (not available in GL40).
