The Roku Ultra 2020(Model # 4800, released October 2020) has 4GB of Channel Storage and 2GB of RAM. the only downside that I was worried about was not having a MicroSD slot but the sheer amount of channel storage has alleviated that worry
The 4800 also has a completely different CPU from the older models, and it is quite fast.
I agree I have my first Roku ultra 4670x works very very well, like the Nvidia shield pro, and apple tv 2021, and the fire tv qube is pretty good two👌👌👌
Very happy with all of these devices all very very good!! But the only one with headphone to fit remote is the ultra from Roku that's why I use it now
