I don't like RISC-V unless it has a good GPU

GPUs are [effectively] irrelevant for many use cases (IoT, embedded, most servers, etc)

the title says "... AI projects". now, maybe our definitions are different, but you probably want some hardware acceleration.

they all suck. someone needs to make an open source gpu already, its been way too long.

We did back in 2007: https://en.wikipedia.org/wiki/Open_Graphics_Project

And there have been some others as well: https://en.wikipedia.org/wiki/Free_and_open-source_graphics_...

Part of the problem is that every ASIC manufacturer (and indeed each fabrication process) has a different toolchain with a different set of primitives for circuit design. Yosys and other open tooling for FPGAs has helped a great deal in lowering the barrier to chip design and by association reuse of circuits. But every ASIC, at the moment, is tied to some vendor's PDK. Here's the one Google open sourced for Cypress Semi's SKY130 process node: https://github.com/google/skywater-pdk

It's probably a series of patent landmines...

Hardware patents are orthogonal to open source software. If a patent covers the hardware then someone who wants to manufacture the hardware needs to license the patent, but you were never going to get free-as-in-beer hardware anyway, and a hardware patent is independent of whether the hardware is fully documented or has firmware with published source code and a license that allows users to make changes to it.

Are there any SBC with memory slot so that i can plug in 32GiB or more of RAM?

Not really. Most in the ARM space, at least, are soldered on or you need to switch out the entire compute module. Intel ones (not mini-PCs, but industrial gear and things like the LattePanda) also tend to have soldered RAM.

Yes, lots of Intel and AMD based SBCs have SO-DIMM slots, but you'll have to accept the 3.5" format.

Regarding RISC-V SBCs, there was serious consideration to release the Milk-V Oasis with SG2380 and LPCAMM2. But this didn't work out as the SG2380 was held up by geopolitical issues.

I had a go at it a few months ago: https://taoofmac.com/space/reviews/2025/05/12/2230

Not bad at all, but the OpenWRT image still didn’t have Wi-Fi support a week or so ago, so I don’t know how good software support is going to be in the long run.

I keep seeing suggestions that theres no software support for Orange Pi. Whats the go there? Is there no distro like Raspbian supporting it?

There are plenty of Orange Pi boards with Armbian or unofficial Ubuntu support, but they’re ARM based.

Xunlong (Orange Pi) operates similarly to Pine64, throw hardware at the community and then let the community figure out the software part.

They provide official OS images at release but don't care much afterwards.
