The coolest of felines over at iFixit have just completed and posted their teardown of Apple’s new 21.5-inch 2015 iMac desktop, revealing a 4K Retina display manufactured by LG display and slightly redesigned Wi-Fi antenna system.
The model, identified as the A1418, also goes by the EMC number of 2889.
Inside, the 21.5-inch iMac looks largely identical to its predecessor, but there are a handful of noteworthy changes. For instance, the hybrid Fusion Drive has a significantly smaller flash partition than the previous generation, iFixit found.
In another small change, the antenna cables are fastened to the AirPort card via screw-secured cable clamps. The AirPort card itself is the same as the 2013 model.
The processor and Thunderbolt 2 controller hail from Intel, the gigabit Ethernet controller is from Broadcom and Cirrus Logic handles the system’s audio controller. Other suppliers include Texas Instruments, Adesto, National Semiconductor, Intersil, Macronix, and Vimicro.
Another unchanged part of the 21.5-inch iMac’s design: The Samsung-manufactured RAM is still soldered to the logic board, meaning users cannot upgrade their RAM from what they initially purchase. This stands in contrast to Apple’s 27-inch iMac, of which the latest model can be upgraded to 64 gigabytes of RAM.
Check out the full teardown for all the specs and if you’ve gotten your mitts on the new 21.5-inch iMac, please let us know what you make of it in the comments.
