The VisionFive V1 single-board computer has been introduced by StarFive. The fact that it is powered by a RISC-V-based SoC rather than an Arm or Intel CPU sets it different from other SBCs, and it is one of the first full-featured variants to enter the market.

RISC-V SoCs are slowly but steadily gaining traction. Open-source alternatives to ARM's proprietary RISC-based chips have piqued the interest of Intel, which is working on its own RISC-V SoC, as well as Chinese companies looking to avoid any bans imposed by the US government, which have seen the likes of Huawei indirectly barred from using Arm-based chips. StarFive, which is based in China, has launched the VisionFive V1 RISC-V single-board computer, which is one of the first full-featured machines to enter the market.

The VisionFive V1 is built on a 1.5 GHz dual-core SiFive U74 SoC on a 3.9-inch x 2.8-inch PCB. In terms of performance, it won't set the world on fire, but it will be an excellent platform for hobbyists and people interested in coding and investigating the chips' AI potential. Hardware-accelerated video decoding for 4K/60 Hz video or two 4K videos running at 30 Hz is also supported. It also has an impressive 8 GB of LPDDR4 RAM, indicating that it is obviously aimed at the Raspberry Pi crowd.
