In its strategy to bring AMD back to reality, Intel keeps releasing Quad Core-based CPUs models.
New models will be a Core 2 Quad clocked at 2.4GHz, and 2 models of Xeon X32x0 (respectively clocked at 2.13 and 2.4GHz). Those Xeons are entry level server CPUs, directly based on Core 2 Duo and featuring a 1066 MHz FSB vs. 1333MHz for the Xeon powering MacPro; however multi CPU feature is supported. If Cupertino does not introduce a desktop between the iMac and the MacPro, then neither the Core 2 Duo nor those entry level Xeon will be used in Apple-branded hardware models.
Apple is expected to release a Quad Core Xeon-based MacPro model as the new high-end model for its Pro desktop (8 cores in total), it would not need any hardware modification, one can simply replace Dual Core Xeon CPU by Quad Core units.
