Is this a developing markets play? I've never heard of someone whose only computer is a Pi/Jetson. By the time you add all the necessary peripherals to use it as your only computer, it costs more than a cheap laptop.
So the point of a Jetson is .. you only have a cheap laptop with terrible integrated graphics, and for $60 you get a much better GPU with this Jetson, and you remote into it?
I think it'll do better in gaming.
Compared to him testing on a Raspberry Pi 4: https://www.youtube.com/watch?v=l4TyYU9Xhcs
(note both those videos are a old so results could be different now)
The video is a year old, but I imagine there would be less bugs now. With this cheaper board coming out, there might be a bit more of development activity.
This Jetson really isn't a platform to run emulated games - for that there are much better boards, with more RAM. Which is a lot more important issue. You can't do miracles with 2GB of RAM.
Jetson is made for computer vision, neural networks and signal processing, where the GPU isn't used as a GPU but as a massively parallel co-processor to crunch through a lot of data at once.
No, not even close. It's embedded systems with GPU acceleration, mostly for machine learning.
