Could RISC-V Processors Compete With Intel, ARM, and AMD?

"As promised, SiFive has unveiled a new computer featuring the company's SiFive FU740 processor based on RISC-V architecture," reports Liliputing:The company, which has been making RISC-V chips for several years, is positioning its new SiFive HiFive Unmatched computer as a professional development board for those interested in working with RISC-V. But unlike the company's other HiFive boards, the new Unmatched model is designed so that it can be easily integrated into a standard PC... SiFive says the system can support GNU/Linux distributions including Yocto, Debian, and Fedora. "SiFive is releasing the HiFive Unleashed in an effort to afford developers the ability to build RISC-V based systems, using readily available, off-the-shelf parts," explains Forbes:SiFive says it built the board to address the market need for easily accessible RISC-V hardware to further advance development of new platforms, products, and software using the royalty-free ISA... A short video demo shows the HiFive Unmatched installed in a common mid-tower PC chassis, running the included Linux distro, with an AMD Radeon graphics card pushing the pixels. In the video, the HiFive Unmatched is compiling an application and is shown browsing the web and opening a PDF. SiFive also notes that video playback is accelerated in hardware with the included version of Linux. "At the moment, these development PCs are early alternatives, most likely targeted at hobbyists and engineers who may snap them up when they become available in the fourth quarter for $665," notes VentureBeat. But they add that "While it's still early days, it's not inconceivable that RISC-V processors could someday be alternatives to Intel-based PCs and PC processors."The startup has raised $190 million to date, and former Qualcomm executive Patrick Little recently joined SiFive as CEO. His task will be to establish the company's RISC-V processors as an alternative to ARM. This move comes in the wake of Nvidia's $40 billion acquisition of the world's leading processor architecture. If Little is also looking to challenge Intel and AMD in PCs, he'll have his work cut out for him. For starters, SiFive is currently focused on Linux-based PCs, not Microsoft Windows PCs. Secondly, SiFive wouldn't build these processors or computers on its own. Its customers — anyone brave enough to take on the PC giants — would have to do that. "I wouldn't see this as SiFive moving out of the box. It's more like they're expanding their box," said Linley Group senior analyst Aakash Jani. "They're using their core architecture to enable other chip designers to build PCs, or whatever they plan to build."
