The most significant improvement in the Apple TV 4K is the inclusion of an A15 Bionic chipset. That’s the same chip that powers the iPhone 13 and 13 Pro, as well as the iPhone SE and the non-Pro iPhone 14. The previous model carried an A12, which was the chip that powered the iPhone XS and XR in 2018, so as you might’ve noticed, it’s quite the upgrade. The inclusion of an A15 chip means you should expect 50% better CPU performance and 30% better graphics performance out of the new unit.
The new generation also supports HDR10+ and Dolby Vision for video, as well as Dolby Atmos, Dolby Digital 7.1, or Dolby Digital 5.1 for audio. This means that whatever streaming service you’re watching, you should be getting the very best experience possible as long as your TV, and your speakers, are up for the task. You also get full access to Apple’s ecosystem of services, including Apple TV+ and Apple Music, as well as Apple Arcade.
