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
Are there any SBC with memory slot so that i can plug in 32GiB or more of RAM?
2 TOPS is not a lot for AI projects.

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.
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)
- go to https://developer.spacemit.com/
- click on documentation
- click on Keystone
- click on K1
No SATA :(
$40 is too expensive
Earlier quoted context omitted.
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…
