Specs on the new iMacs include, as previously mentioned, Intel’s new “Penryn” Core 2 Duo processors with 45-nanometer technology (which means it’ll be far more energy efficient than previous 65nm based iMacs and run significantly cooler at comparable clock rates), 6MB on-chip Level 2 cache, 1066MHz Frontside Bus (FSB), and speeds of 2.4, 2.66, 2.8 or 3.06GHz are available.
Providing two display options and four different clock speeds will give Apple’s flagship Mac a huge range of price points and customization possibilities.
Along with a bump in preinstalled memory — 1GB for the entry-level 20in model and 2GB for all others — the type of RAM used has been bumped up to 800MHz DDR2 from 667MHz.
There are still only two RAM slots, however; so one will have to remove the existing paired RAM and install it in matched pairs (supporting up to 4GB with 2GB DDR2-800 SO-DIMMs) to upgrade the iMacs’s memory.
Despite that limitation, the upgrade process is quite easy — particularly compared to virtually any other computer that can remotely compare with the iMac’s compact and powerful design.
As for graphics acceleration, the new iMacs are bumped up considerably — most notably at the high end, but pretty much across the board except for the entry-level which retains a Radeon HD 2400XT GPU with 128MB of GDDR3 VRAM.
