I’ve updated the 24-inch iMac Performance (August 2007) article to include Geekbench results for the 24-inch iMac with the Core 2 Extreme processor. It looks like the Core 2 Extreme brings noticeable processor performance gains (take a look at the integer and floating point scores below), but is comparable in terms of memory performance with the 2.4GHz 24-inch iMac (unsurprising, since both iMacs use the same speed memory).

For your convenience, I’ve done a “mini comparison” between the two current 24-inch iMac models below.

Setup

  • iMac (24-inch Mid 2007)
    • Intel Core 2 Extreme @ 2.8GHz
    • 2.00 GB 667 MHz DDR2 SDRAM
    • Mac OS X 10.4.10 (Build 8R4031)
  • iMac (24-inch Mid 2007)
    • Intel Core 2 Duo @ 2.40GHz
    • 2.00 GB 667 MHz DDR2 SDRAM
    • Mac OS X 10.4.10 (Build 8R4031)
