Intel's Haswell architecture increases performance relative to Ivy Bridge running at the same clock speed, but Intel's latest architecture is much more focused on battery life improvements than performance improvements. The 2013 iMac's innovations are entirely interior, and there are four upgrades of consequence: the Ivy Bridge CPUs have been swapped for newer Haswell versions the 6-series Nvidia GPUs have been switched for an Intel integrated GPU on the lowest-end iMac and 7-series Nvidia GPUs everywhere else the SATA solid-state drives in the SSD- and Fusion Drive-equipped models have been switched for a PCI Express version and the dual-band 802.11n Wi-Fi has been upgraded to the better-performing 802.11ac.
#Late 2013 imac 21.5 ram upgrade upgrade
The 21.5-inch has two RAM slots on the inside (capable of supporting up to 16GB of RAM) that can't be accessed without tearing the machine apart, so if you think you'll want the memory eventually you'll probably want to cough up $200 for the upgrade when you buy the computer. Finally, just like last year, the 27-inch iMac is the only model that retains user-accessible RAM slots (it has four, which support up to 32GB of RAM when fully populated). Last year we found them to be a modest improvement over the 2011-and-older models' single-mic setups when chatting or using OS X's dictation feature, and this year's iMac performs similarly. Like the 2013 MacBook Airs, these late-model iMacs also include two built-in microphones that help with noise reduction. FireWire has been dumped entirely from these newer Macs, but an adapter exists if you still need that particular interface. 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.
