Notes
Both 2.66 GHz models used the NVIDIA GeForce 9400M graphics chipset, which used a portion of main memory as VRAM. Though reported as a 256 MB graphics system, the chipset actually used up to 272 MB of RAM. The 20" model weighed 20 pounds, consumed 200 watts of power, and had the following dimensions: 18.5" H x 19.1" W x 7.4" D. The 24-inch, 3.06 GHz model had an NVIDIA GeForce GT 130 graphics chipset with 512MB of GDDR3 memory.
Introduced in March 2009, the iMac (Early 2009) was largely a speed-bump of the iMac (Late 2009)
