Everything is a lot smoother and faster on the 4K models. There are small advantages too. 4K 1st gen adds support for HomePods as speakers. 4K 2nd gen adds support to send TV and game system audio to HomePods. 4K 3rd gen adds HDR10+, which is great if you have a newer TV without DolbyVision. 4K 2nd/3rd gen greatly reduce network latency which is great for game streaming (such as Steam Link).Is there any use buying this if you:
A) Already have an Apple TV HD? and;
B) Don’t have a 4k TV (but have plans to get one eventually)?
I only use it to watch shows on Netflix or Amazon Prime. I don’t play music on it much, nor do I game on it. I think that’s because I know that trying to do so will be painful given the old A8 (?) chip in it. If I had more performance behind it I might be tempted to do more with it.
