MacBook Pro and iMac are set to an update with the new Intel Ivy Bridge CPUs. The upgrades could around the corner as new high performance MacBook Pro laptops and iMac All-In-One computers appeared in online benchmarks.
Intel is rolling out new Core CPUs, widely referred to as Ivy Bridge. MacRumors reports that new 2012 MacBook Pro laptops and 2012 iMacs have been spotted in an online benchmark database. It could be that Apple or one of their partners has run a benchmark and did not release that those are shared.
The spotted MacBookPro9,1 and iMac13,1 carry a reasonable better benchmark score than current released systems, making the reports to be likely authentic.
In any case, it is a good idea to hold off on any iMac and MacBook Pro purchases until Apple is adopting the Ivy Bridge CPUs. The new MacBook Pro might also sport a new design. I expect them to come already end of the month, before the WWDC 2012.
