The iMac Intel 20" EMC 2266 looks nearly identical to the first generation aluminum iMacs. The differences lie within, with the most noticeable hardware change being a surface mount GPU soldered directly to the motherboard as opposed to a removable video card on earlier aluminum iMacs. The 2.66 Core 2 Duo "Penryn" processor, with 6 MB of shared L2 cache, opens the capability to support 8 GB of PC3-8500 RAM.
The style of the new aluminum iMacs are a dramatic departure from the white plastic encased iMacs of the past. The aluminum iMacs were to match the design of the original iPhone, both released at nearly the same time. The glass front panel allows for a richer viewing experience, and even with aluminum and glass accents the 20" aluminum iMac is still lighter than all previous 20" iMac generations.
