The Xuantie 910 core is claimed to be roughly equivalent to an ARM A53, so at the stock 1.2 GHz this should be close to a Raspberry Pi 4 and considerably faster than the Pi 3 equivalent HiFive Unlimited.

The price of course is still well above Pi levels. Existing and working is by far the biggest and most important step, mass production and lower prices comes afterwards.

I don't know whether this SoC has taken the RISC-V Vector extension option for the C910, or what version it would be if so -- most likely draft 0.7.1 like the Allwinner D1 (with C906 core) I'd imagine.

The boards are different but the chip has the same markings as the chip on this board running AOSP on RISC-V.

So it should have a 3rd RV64GC + Vector draft 0.7.1 core capable of 2 128 bit vector ALU operations, 1 vector load, 1 vector store per cycle.
