Instead, upgrading to 16GB of memory has to be done at the point of ordering.These new iMacs have the same four USB 3.0 ports, dual Thunderbolt ports, SDXC card slot and gigabit Ethernet port as the late 2012 models.

Again, there's a Core i7 option for online orders, this time running at 3.1GHz (up to 3.9GHz Turbo Boost). 8GB of DDR3 memory is included as standard, and can be either upgraded through Apple's own store to up to 32GB, or – by popping off the small hatch on the rear of the iMac – fitting your own choice of third-party memory.Īs for the 21.5-inch iMac, that kicks off with a 2.7GHz quadcore Core i5 (up to 3.2GHz Turbo Boost) with a 2.9GHz quadcore Core i5 (up to 3.6GHz Turbo Boost) in the higher performance model.

Our review unit has been upgraded to the 3.5GHz quadcore Core i7 (up to 3.9GHz Turbo Boost), which is an order-only option.
