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 SK Hynix. That's up from 2GB RAM in the previous Apple TV.

The new power supply is rated for 12V at 1.083A, a modest increase over the 12V at 0.917A power supply in the previous 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 repairability score of 8 out of a possible 10 points. The device is easy to open and has modular components, but they're soldered to the logic board, so board-level soldering or full board replacements are required.

I am absolutely loving mine so far. Even with the resolution increase, it is noticeably snappier than my 4th gen models. Launching apps, using the switcher, boot up, everything is just a breeze. Also, watching 4 simultaneous football games in 1080p HD through the new ESPN app is some kind of magic.

I am not sure removing the USB-C port was a particularly great idea. Sure, xCode 9 can deploy via wireless network, but what if, as a developer, you end up in the situation where you've no network access. It does happen! I don't care about Kodi and the likes, but from a developer's perspective I think this just made things a bit less friendly.

I have to be honest, compared to the shield, this is the biggest piece of garbage I have seen. Doesn't support Atmos, and the thing tries to make everything HDR. Also wouldn't play any of my UHD videos on plex without transcoding (which could be a plex issue but still).

Shield out of the box supported everything and works flawlessly.
