RISC-V is one of the latest contenders in the CPU field, but what is it and how does it compare to its rivals? Even for computer geeks, RISC-V is a bit in the weeds, but maybe not for long. It is one of the rising stars in the computing world and is one of the most successful (if not the most successful) examples of open source and open standard hardware. Tens of billions of RISC-V cores are expected to be sold in the coming years, a number that would rival the number of x86 and ARM cores sold in the same time period. Here's everything you need to know about RISC-V and where it's going. RISC-V (pronounced "risk five") is an instruction set architecture (ISA) developed and maintained by RISC-V International (formerly the RISC-V Foundation). An ISA is the starting point of any CPU design and determines fundamental things like basic instructions, what optional instructions can be added, and what type of software can run natively on the CPU. Additionally, RISC-V is, by na...
