All of the back-mounted ports remain as annoying as ever to reach around and find, but you get the same number of them as you did last year: one gigabit Ethernet port, two Thunderbolt ports ( not Thunderbolt 2, mind) four USB 3.0 ports, an SD card slot, and a headphone jack that can also accept input from headsets. Like last year's iMac, the new model is extremely thin around the edges and bulgy in the back.

The 2013 iMac is externally identical to the 2012 model right down to its odd trapezoidal box and its wireless mouse (or trackpad) and keyboard, but we'll recap for those of you with older models. And if you didn't buy a 2012 model, is there any one upgrade that will encourage you to buy a 2013 model instead, or should you be waiting for a more drastic upgrade? Body and build quality Still, we've got the $1,299 base model in for testing. If you were waiting for a Retina iMac to be released this year, your best bet is to keep on hoping. The 2013 iMac's new changes are all internal-slightly upgraded CPUs and GPUs, a new 802.11ac Wi-Fi adapter, and a switch from SATA to PCI Express solid-state drives round out a refresh that makes absolutely no external changes to last year's chassis.

Less than a year passed between the introduction of the 2012 iMacs and this year's quiet refresh, and the changes are accordingly much smaller. The computer got much thinner, lost a few pounds, and ran much cooler and quieter than previous models, and it also got a decent internal upgrade courtesy of new Ivy Bridge CPUs from Intel and dedicated Nvidia GPUs. More than a year and a half passed between the introduction of Apple's 2011-model iMacs and the refresh that replaced them late last year, but the changes you got for waiting were reasonably substantial. 2.7GHz Intel Core i5-4570R (Turbo Boost 3.2GHz)ĨGB 1600MHz DDR3 (upgradeable, but not user-accessible)Ĩ02.11ac, Bluetooth 4.0, gigabit EthernetĤx USB 3.0, 2x Thunderbolt, headphone jack, SD card slotġ7.7 x 20.8 x 6.9 inches (45.0 x 52.8 x 17.5 cm)ħ20p FaceTime HD camera, dual noise-canceling mics, ambient light sensor, Kensington lock slot
