Apple recently updated its iMac line, updating the components without touching the brushed-aluminum-and-glass design that it introduced last August. As in the past, Apple sells four iMac models--two 20-inch models and two 24-inch models--each of which allows for some degree of customization. The four default models keep their previous price points while moving to Intel Penryn processors, which offer higher clockspeeds and more L2 cache and operate on a faster 1066MHz frontside bus. Please see our full review of the 2.8GHz, 24-inch iMac for more information, including performance analysis.

Of the two 20-inch models, the biggest change with this update comes with the higher-end $1,499 model, which now offers 2GB of memory--double the amount offered by the previous model at that price point. All iMac models now use 800MHz DDR2 SDRAM--faster than the 667MHz memory from previous-generation iMacs. Aside from the new Penryn processors and memory differences noted here, the rest of the components remain unchanged from the previous generation 20-inch iMacs.

The highest-end 24-inch iMac model received the largest update this round, receiving both a processor and graphics bump. The $2,199 model features a 3.06GHz Core 2 Duo chip and a 512MB Nvidia GeForce 8800 GS graphics card. One of the few complaints we had with last year's 24-inch iMac was the fact that the otherwise high-end configuration saddled you with a midrange graphics card. Now, you get a 512MB Nvidia GeForce 8800 GS, a more powerful graphics card than the 256MB ATI Radeon HD 2600 Pro it replaces. The GeForce card is a $150 upgrade option on the $1,799 model, while moving from the 2.8GHz CPU to the 3.06GHz Core 2 Duo is a $200 upgrade. You can also choose to double the RAM to 4GB for $200. Hard drive capacities go up to 1TB; it's a reasonable $300 upgrade from the 320GB drive and $250 from the 500GB drive.

Apple iMac currently ship with integrated draft 802.11n Wi-Fi, Bluetooth 2.1 EDR, Mac OS X Leopard (version 10.5.2), and iLife '08.
