Geekbench 2, the benchmark used by all those who want to test the performance of iDevices, was recently updated, the new version bringing support for multi-core processors and for detecting their frequencies. All the information that appeared recently on the Internet suggests that the iPad 2 and iPhone 5 will have dual-core processors again launch this version of Geekbench only comes to confirm this. Regarding the support for detecting the processor frequency, we could talk about support for new models of ARM processors with dynamic frequency, which changes according to the workload for a reduced energy consumption.
It is possible that the developers of the Geekbench 2 application have updated the application only with the idea of being "covered" for the moment when these devices will be launched, but all the information indicates that we will have new dual-core processors in iDevices.
