A teardown video, shared by OWC, reveals the internal changes in the new 2020 27-inch iMac.
The 2020 27-inch iMac was announced earlier this week with 10th-generation Intel Core processors, AMD Radeon Pro 5000 series graphics, up to 128GB of RAM, up to 8TB of storage, a 1080p front-facing FaceTime camera, a True Tone display with a nano-texture glass option, higher fidelity speakers, and studio-quality microphones.
MacRumors forum user TwoH summarizes the changes:
– Camera is attached to the LCD, so have to take extra care to remove a third cable when opening up the iMac.
– Lack of mechanical HDD (and SATA connectors on logicboard) – but this was obvious.
– Extra microphone(s) stuck to the case, notably an extra cable made connecting into the logic board close to the backlight. Other connects around the same position as the 2017/19 models.
– Solder joints for the 4 & 8TB model iMacs.
The biggest change inside the 2020 27-inch iMac is the lack of mechanical hard drive, as all models now come with SSDs by default. OWC notes that the disassembly now seems faster for this reason. There are no longer any SATA connectors in the machine and a small SSD is soldered directly to the motherboard. Instead, there are new solder joints for an expansion board to hold additional SSDs in the 4TB and 8TB configurations. In the 256GB, 512GB, 1TB, and 2TB configurations, the expansion board is not present.
