This week's Apple announcement saw the release of new iMacs with Ivy Bridge CPUs. So what does this mean for us?
The good news is Apple is still using desktop CPUs in the iMac. This means that in a future Mountain Lion update we will see official native desktop 7-series chipset support. No more "Unknown AHCI Standard Controller" in System Profiler.
On the graphics front, all Apple Ivy Bridge based products now have either Intel HD 4000 or NVIDIA Kepler mobile graphics. Since Apple dropped the ATI/AMD mobility cards from the iMacs, I wouldn't hold out hope for AMD HD 7xxx support coming anytime soon.
Looking for more information on the CPU models, I did a quick search on the CPUs based on the specs on the Apple website and have come up with the following detailed CPU specs:
iMac 21" 2.7GHz quad-core Intel Core i5 processor (Turbo Boost up to 3.2GHz) with 6MB L3 cache
is most likely the Intel Core i5-3330S
iMac 21" or 27" 2.9GHz quad-core Intel Core i5 processor (Turbo Boost up to 3.6GHz) with 6MB L3 cache
is most likely the Intel Core i5-3470S
iMac 21" 3.1GHz quad-core Intel Core i7 (Turbo Boost up to 3.9GHz) with 8MB L3 cache
is most likely the Intel Core i7-3770S
iMac 27" 3.2GHz quad-core Intel Core i5 processor (Turbo Boost up to 3.6GHz) with 6MB L3 cache
is most likely the Intel Core i5-3470
iMac 27" 3.4GHz quad-core Intel Core i7 (Turbo Boost up to 3.9GHz) with 8MB L3 cache
is most likely the Intel Core i7-3770
Each link above references the Intel spec sheet for each CPU model. When you look at these specs, don't get excited that some of these Ivy Bridge chips are have onboard Intel HD 2500 graphics. I'm almost certain that Apple will not enable them at all, and will only support the discrete NVIDIA Kepler GPUs.
