Notes

The MacBook Air's graphics chipset used a portion of main memory as VRAM. Though reported as a 256 MB graphics system, this was actually a minimum. Actual usage varied with graphics load, resulting in slightly less RAM available for system use. When upgraded to 4 GB of onboard RAM, the minimum VRAM increased to 384 MB.

Introduced in July 2011, the MacBook Air (11-inch, Mid 2011) was based on Intel's next-generation "Sandy Bridge" architecture, and improved on its predecessor, the MacBook Air (11-inch, Late 2010) with faster processors and graphics, a backlit keyboard, and the inclusion of Apple's new Thunderbolt port. It shipped in two configurations:

1.6 GHz Dual-Core Intel Core i5, 64 GB SSD, 2 GB of RAM, $999
1.6 GHz Dual-Core Intel Core i5, 128 GB SSD, 4 GB of RAM, $1199

4 GB of onboard RAM was available for the low-end model as a Build-to-order option (no aftermarket RAM upgrade was possible). Options for the high-end model included a 1.8GHz Dual-Core Intel Core i7, and 256 MB of flash storage. The MacBook Air (11-inch, Mid 2011) was replaced in June 2012 with the MacBook Air (11-inch, Mid 2012)
