![]() ![]() For artists and designers, and of course gamers, that means better performance for their graphics-intensive apps.Īpple made two major changes regarding the rear ports. The 2.93GHz iMac uses Nvidia’s GeForce GT 120 and the 3.06GHz iMac uses Nvidia’s GeForce GT 130 those two iMacs have 256MB and 512MB of dedicated video memory, respectively. The two 2.66GHz-based iMacs use Nvidia’s GeForce 9400M, which shares 256MB of memory with the CPU. The iMacs no longer use ATI graphics subsystems as standard equipment. Now, the entry-level iMac has a 320GB drive, the high-end iMac has a 1TB drive, and the two models in between have 640GB drives. Previously, there was a 250GB drive in the entry-level iMac, and 320GB drives in the other models. The hard drives in the standard configurations received a nice jump in capacity, too. Apple also doubled the amount of RAM in the standard configuration, with 2GB in the 20-inch iMac Core 2 Duo/2.66GHz, and 4GB in the other three models. The system bus, used in communications between the processor and system memory is still at 1,066MHz, but now Apple uses 1,066MHz DDR3 RAM instead of the 800MHz DDR2 RAM in the previous iMac-this bump in RAM speed also contributes to the impressive speed increase over the previous iMac. Previously, iMac processor speeds started at 2.4GHz, and included 2.66GHz, 2.8GHz, and a built-to-order 3.06GHz. The iMac’s Core 2 Duo processor speeds start at 2.66GHz, and include 2.93GHz and 3.06GHz. Apple has released four new iMacs-one 20-inch model and three 24-inch models, with clock speeds from 2.66GHz to 3.06GHz.īehind the glossy screen is where all the changes have been made, resulting in a performance boost that reinforces the iMac’s value. The 24-inch LCDs, at 1,920 by 1,200 pixels, are 8-bit displays and look good at an angle. But the display does look brighter than the previous 20-inch iMac display. And like that previous display, the new 20-inch iMac, when viewed at an angle, shows color and contrast shifts. The 20-inch LCD is 1,680 by 1,050 pixels, and is a 6-bit color display that achieves millions of colors by dithering, like the previous 20-inch iMac display. The iMacs still use TFT active-matrix LCDs. ![]() Apple offers four standard configurations of the iMac, three 24-inch models and only one 20-inch iMac. ![]()
