iFixit has shared an Apple TV 4K teardown, providing a closer look at the device’s internal design and components.
We already know the Apple TV 4K is equipped with Apple’s 64-bit A10X Fusion chip, and now the teardown confirms the device has a total of 3GB of LPDDR4 RAM supplied by South Korean company SK Hynix.
The new power supply is rated for 12V at 1.083A, a modest increase over the 0.917A power supply in the fourth-generation Apple TV.
According to the teardown, Apple merged the new fan with the heat sink/EMI shield assembly from the fourth-generation Apple TV to create a larger thermal assembly for cooling and ventilation.
iFixit said the bottom of the unit has been redesigned with a total of eight exhaust ports and a new, replaceable fan driven by a Nidec brushless motor.
Beyond the return of a Gigabit Ethernet port and the removal of the USB-C diagnostic port, which we learned about before the teardown, the Apple TV 4K’s design is largely the same as the previous Apple TV.
iFixit gave the Apple TV 4K a so-called repairability score of 8 out of a possible 10 points. The device is easy to open and has modular components, making for easy disassembly and repair. All major components are soldered to the logic board, however, so board-level soldering or full board replacements are required.
