Maybe one or some of you can help me
I'm having an "old" Raspberry (https://en.wikipedia.org/wiki/Raspberry_Pi) 3B running Kodi (https://en.wikipedia.org/wiki/Kodi_(software)), or more accurate Xbian (https://xbian.org), to stream movies and shows and stuff like that from my NAS via WiFi. As for the moment this works really good, but i just stream full-hd (1080) or smaller material. Now that i have switched my TV to an 4K one, and the Raspberry Foundation released the new Pie 4 (which is capable of playing 4k-material), i'm thinking about switching to this new one. They are cheap, even if i had to buy the complete gear new (case, power supply and so on) it's under 100 bucks.
The question is, how much RAM do need to stream 4k-material?
They released the Pie 4 in three types: 1GB RAM, 2GB and 4GB. Do i really need the 4GB-model? Or am i fine with 2 or even 1GB? Thing is that the 4GB is about 20 money more expensive compare to the 1GB one, and for 20€/$ you can buy the case and the power supply so i would safe some money.
I knew i could just install the Kodi-app on my Xbox One X, but i don't want to run the Xbox everytime to watch a movie or an episode from some television shows - the Pie has just a trickle of power comsumption compared to the Xbox.
Any advice?
I don't think you can do it with less RAM than that.
I would go with 4GB option.
