A few days ago, Other World Computing (OWC) had come forward and published a first disassembly of the iMac Pro. But we couldn’t help but cover the traditional iFixit, because the guys always bring beautiful images and an accurate analysis of teardown.
When opening the machine, iFixit proved that this is not just an “iMac with a new skin”. In fact, all of its internal components have been reconfigured to prioritize its cooling system based on a cooler double.
Before we go any further, here’s the iMac Pro in all its glory:
As we had already learned from the disassembly of the OWC, the iMac Pro (model A1862) proved to be more modular in practice than Apple initially implied. Opening it is not for everyone, but anyone who is adventurous and has experience with it, or even anyone who wants to update it with specialized technical assistance, can.
Three of the main components of the iMac Pro are replaceable: RAM, CPU and SSD. The GPU is out of this, so the tip from iFixit, to those who are going to invest in this machine, is to buy it with the toughest graphics card – that is, the Radeon Pro Vega 64 with 16GB of HBM2 memory (US $ 600 more in the United States, R $ 4,200 here in Brazil).
IFixit also noted the presence of the T2 chip, responsible for SMC functions, image processing, audio control, SSD controller, Secure Enclave and the hardware encryption mechanism. We talk more about him in this article.
Also according to iFixit, the iMac Pro’s 5K screen is manufactured by LG and is exactly the same as the “normal” 27-inch iMac (model LM270QQ1). However, due to the use of a new cable and changes to the iMac Pro camera (which is Full HD 1080p), it is not possible to interchange them.
Due to the difficulty of opening the iMac Pro and thus accessing its internal components, iFixit gave it a rating 3/10 in “repairability” – the same as the 21.5-inch iMac, with 4K screen.
