I watch a bunch of weekly anime stuff myself. Never have to worry about transcoding with my devices (locally) and just directplay it. Unless I watch it remotely then it transcodes, I never mess with the default settings and it’s fine.
My cpu is i3 8100 so I think you would be fine as well, unless it’s multiple streams at once I have no reference for that.
I don’t own an e-reader but if I’m not mistaken, kavita has a KOReader plugin so it probably possible to use it with an e-reader, android reader has many more options I think.
