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

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

It is at least theoretically possible to build a headless "GPU" from RISC-V processors that have the vector extension (RVV). RVV had been designed to be able to run programs compiled for the SIMT execution model that most GPUs use.

This Orange Pi RV2 has a small vector unit in each core, and could be used for at least prototyping the software until more powerful chips are available.

BTW. There have also been a couple hardware startups that have been working on commercial GPUs based on RISC-V's vector extension, with their own GPU-specific instruction set extensions for texture lookup and the like.

Earlier quoted context omitted.

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.

The chip (KY X1) comes with AI acceleration...

RISC-V going forward, one of the only beacons of hope in the silicon world.

I need one of such devices for my self-hosted services. And it will be time to port from C to assembly, really, because we have finally a CPU ISA which is 'sweet spot' balanced, standard, global, pushed forward with significant resources and without IP locks anywhere. No more developer/vendor lock-in via "the only compiler able to generate correct machine code", extremely hard to do planned obsolescence, etc, we need mainstream adoption NOW :)

The main blocker: how do I buy such device with a noscript/basic (x)html browser? And no way I use a credit card on a web site: would require well identified bank swift account, or wallet codes bought from local and physical currency terminals. I don't know of any local retailers I can buy such device from. Yep, the "web geniuses" at amazon (which supports wallet code) broke noscript/basic (x)html support a few years ago.

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's a RV64 port of Debian and the RV2 and R2S are on the list of compatible hardware. No guarantee it'll be easy getting it loaded, it was like pulling teeth to get it on the SiFive U74 board, but that was 7 years ago, so it's GOT to be better by now.

Absolutely smoked by rpi5, often by rpi4. To make matters worse, a radically unsupported core with no mainline support. https://www.phoronix.com/review/orange-pi-rv2-benchmarks/2

Don’t think people buy riscv for their performance competitiveness at this stage

Most likely comming in vector, matrix instructions or NPU like chipsets, not necessarly GPUs.

Don't suppose there's actually documentation for the CPU anywhere? (I mean more than a tiny "datasheet" with a very high level overview and/or a pile of random Linux/uboot patches)

Raspberry wouldn't be the market leader if Orange, Rock and the rest could write documentation and support to save their life.
