Don't let the AI-heavy marketing distract. It's an Ubuntu PC effectively.

I have successfully used the Pi4 at 4K. It is a very slow computer for “normal computing purposes” though.

Can you elaborate what you're doing that is slow? In my experience, CPU wise it's plenty fast, matching typical desktop from 2008. Although memory bandwidth could be better...

It's slow at 4k. I've got the 4GB variant and in 1080p it's good, I'd even say surprisingly so.

Ah, so you mean graphics performance. Yeah, just not enough memory bandwidth. 32-bit DDR4 memory interface is a bit narrow for 4k use!
