is there any comparable risc-v option?
STAR64? Don't know how they compare on benchmarks, but Pine64 has a few products that are risc-v.
Afaik the StarFive SOCs used in SBCs are a lot slower than current ARM offerings. Part of that might be because software support is worse, so maybe compilers and related tooling aren't yet optimized for them?
Hopefully development on these continues to improve though. The biggest nail in the coffin for Pi alternatives has been software support.
It's also a super new architecture and completely open source. Development will simply be slower. There's enough "mainstream" Pi competitors with risc-v offerings though that I'm confident that it will happen.
STAR64 is an ARM board. Pine64 is definitely eyeing RISC-V heavily but last I checked the only product that actually shipped with a RISC-V CPU is the pinecil featuring a SiFive E24, a beefy microcontroller. Ridiculously beefy for a soldering iron, but a microcontroller nonetheless.
Killing off ARM in that segment is still some ways off but RISC-V already has a firm foothold in the microcontroller space. Also Arduinos are absolutely overpriced which doesn't help them a bit.
What?
STAR64 is Risc-V.
They also have the Pinetab-V, which uses a 64-bit Quad-core 1.5 GHz SiFive U74 RISC-V chip.
The Pinecil was their first Risc-V product and the first commercial product with Risc-V made by anyone.
Quoth the first link you posted:
...as said, I haven't kept up to date. Don't shoot the messenger shoot Pine64's webdev.
As a dedicated and user-programmable device, probably yes but e.g. Seagate has been shipping HDDs with RISC-V controllers for ages. Apparently they want/need custom silicon and paying ARM for a CortexM0 license was just something they decided wasn't necessary, and actually annoying as you can't easily extend the ARM to include custom instructions, ARM is very protective of compatibility and everything.
