iFixit has posted a hardware teardown of the new fourth-generation Apple TV, providing a closer look at the set-top box's A8 chip, flash storage, redesigned power supply with a larger heat sink and other logic board components. The website also provided a teardown of the accompanying Siri Remote.

Under the hood, the new Apple TV features a dual-core, 64-bit Apple A8 chip with 2GB of SK Hynix LPDDR3 SDRAM, custom Apple memory controller, SK Hynix NAND flash storage, Universal Scientific Industrial Wi-Fi module and SMSC USB 2.0 to 10/100 Ethernet controller.

The new Apple TV also has a larger heat sink, which is likely a contributing factor to the set-top box's taller form factor. The redesigned power supply is rated at 12V at 0.917A, compared to the third-generation Apple TV's rating of 3.4V at 1.75A. The heat sink is situated above the heat-sensitive logic board.

The teardown of the Siri Remote reveals a ST Microelectronics low-power ARM Cortex-M3 MCU, Qualcomm CSR1010 Bluetooth radio, Texas Instruments low-power digital signal processor, the same Broadcom touch screen controller used in the iPhone 5s/5c and iPad Air, 410 mAh battery and a few other chips.
iFixit gave the new Apple TV a strong repairability score of 8 out of 10, with ten being the easiest to repair, because it has only a few major components, a replaceable power supply and standard Torx screws. It also found the Siri Remote has a wide gap, making it easy to pry apart for repairs.
