At first glance, the HiFive Unmatched from SiFive looks like just another mini ITX computer motherboard. But rather than an x86 chip, this system is powered by RISC-V processor.
First introduced last fall, the board is aimed at developers rather than the general public, and with a $665 price tag, it’s a lot more expensive than some other RISC-V development boards. But the HiFive Unmatched is also one of the most powerful products in this emerging category to date, thanks to SiFive’s FU740 processor.
