Yes, but it doesn't have arm levels of growing pains.

Current risc v SBCs are about 10 years behind performance wise, which isn't as much of a problem. Core count is there, just not single core performance.

I'm only aware of one RISC-V system where I can say the core count is there: the Milk-V Pioneer board and its 64-core SG2042 processor from two years ago. It's comparable in price to a 64-core ARM Ampere CPU+motherboard (USD$1500 for the board), which seems somewhat reasonable when not considering the performance of each core. Hopefully the C930 core described in this article leads to more systems that aim for multi-core performance.

Most RISC-V development boards are only 4 cores or fewer, with just a few popping up in the last year with 8 cores and nothing higher besides the SG2042. The best single-core RISC-V performance so far is on the SiFive P550 but it's only 4 cores and comes on a development board that costs USD$500 (plus another $150 for tariffs if shipping to the US). You could easily get a 12-core AMD CPU and motherboard combo for less than that.

There's also the deep computing mainboard from framework. Also that p550 uses a new CPU while the mainboard uses a jh710.

The p550 is less rpi and more like those rockchip powered boards from radxa. (ignoring core count).

I was only talking about high core count and high (relatively speaking) single-core performance. The DeepComputing Framework board is neither. Its JH7110 is only 4 cores and a rather old processor, which seems like an odd choice for a product releasing in 2025. At least the software support is great since distros have been working with VisionFive 2 and Milk-V Mars for years.

It's also the only currently-available Framework 13 board with fewer than 6 cores, though core count isn't remotely comparable between architectures. At this price ($209 for lone board with 8GB RAM, $799 for full laptop) I'd prefer to see something at the very least comparable to SpacemiT K1, which has 8 cores and vector support, and is on the Banana Pi BPI-F3 (8GB version is $95).
