Apple iMac’s get new Intel Penryn CPU

Apple has refreshed their iMac desktop lineup with the new Intel Penryn processors.  The Penryn chips are 45nm process that provides increase onboard L2 cache memory along with lower power consumption.  The Reg reports:

“The standard three iMac configurations again include a pair of 20in, 1680 x 1050 models and a version with a 24in, 1920 x 1200 display. Moving up the line, the Core 2 Duos are clocked at 2.4GHz, 2.66GHz and 2.8GHz, respectively. All three CPUs sit on 1066MHz frontside buses and contain 6MB of L2 cache.

Curiously, Intel’s price list doesn’t currently include 1066MHz FSB Core 2 Duos that also contain 6MB of L2, so these are either 1333MHz desktop parts underclocked, or 1066MHz ‘Montevina’ laptop processors that Apple’s got ahead of the upcoming Centrino 2 launch.

Despite the faster FSB, the iMacs still come with 800MHz DDR 2 memory; 2GB of it in all but the entry-level configuration, which has 1GB. All three desktops have dual-layer multi-format 8x DVD writers, and 250GB or 320GB of 7200rpm SATA hard drive storage.”
