Apple’s new iMac with Retina 5K display flaunts 14.7 million pixels, but apparently apart from the shiny screen, everything else underneath the device is the same as previous generation models, as revealed by the folks over at iFixit.
In the latest teardown treatment, iFixit found that the new iMac employs many of the same design elements from previous iMacs. It still boasts the easily accessible RAM slot, the same SSD, and logic board. Though, the processor, GPU, and display controller (sporting a wider display data cable) have received significant upgrade, of course. The teardown also revealed that the 5K display, which sports the screen resolution of 5120 x 2880, has been manufactured by LG Display. It is the same supply partner that has also manufactured previous generation iMac displays.
The model of Retina iMac that iFixit folks cracked open was powered by an AMD Radeon M290X GPU paired with i5-4690 processor from Intel. It also comes with 256 MB GDDR5 SGRAM made by SK Hynix. As far as the SSD is concerned, it is the same SanDisk PCIe model as used in the late 2013 Retina MacBook Pro. The AirPort and Bluetooth card are also the same as in the 2013 27-inch iMac.
The best revelations that comes out of all this disassembling is that the GPU, SSD, and RAM are all upgradeable. However, you will still have to cut and then replace the special double-sided tape, which is easier said than done. This was one of the reasons why iFixit gave the new iMac a repairability score of 5 out of 10.
