**StarFive has officially unveiled the JH7110 quad-core RISC-V processor with 3D GPU and the VisionFive 2 SBC. I just did not expect the company to also launch a Kickstarter campaign for the board, and the version with 2GB RAM can be had for just about $46 for “early birds”**

**StarFive will provide Debian and Fedora operating systems images for the board. The company also provides some interesting benchmarks showing the CPU performance is actually higher than Cortex-A55-based chips, but not quite up to the performance of the Broadcom BCM2711 quad-core Cortex-A72 processor used in the Raspberry Pi 4.**
