As with the iPhones 5s and 5c, the iFixit it also disassembled the new iMacs to check the internal news of this new generation, which has the fourth generation of processors quad-core from Intel (codenamed Haswell), updated graphics, Wi-Fi 802.11ac (Gigabit Wi-Fi) and faster flash storage options, with PCIe interface.
The changes were small, but they deserve to be highlighted.
The 21.5 ? model (EMC 2638) brought two new features. The good news is that consumers can now add a second HDD through the Fusion Drives SSD port even though the machine has not left the factory equipped with the storage drive that combines a high-capacity hard drive with high-performance flash storage. As this port is now PCIe, this should facilitate the arrival of units / adapters on the market capable of allowing the installation of a second hard drive.
But the good news ends here. Now, the CPU (central processing unit, or central processing unit) is soldered to the logic board and can no longer be replaced by the user. This is apparently the first iMac with a soldered CPU. In addition, the new AirPort (BCM4360 802.11ac) / Bluetooth 4.0 (BCM20702) card is attached to the back of the logic board, making it difficult to exchange.
The SATA power and data cables, from HDDs, now come together, accompanied by a new heatsink for the CPU. The 27-inch iMac has the same novelties as the smaller brother, with the exception of the CPU soldered to the plate, which is good news for those who like repairability.
Because of these changes, the smaller iMac earned a 2/10 score, while the highest iMac scored 5/10.
