At A Glance

Apple boosts the processor in its 20-inch iMac to 2.16GHz. And this isn't just a mere jump in clock speed -- the old Core Duo chip has been replaced with a next-generation Core 2 Duo that boosts the amount of shared L2 cache to 4MB. Other than the larger screen size, faster processor and bigger hard drive, the specs on this model match the 17-inch iMac Core 2 Duo/2GHz. Build-to-order options include a 2.33GHz Core 2 Duo processor and a 500GB hard drive.
