The rise of RISC-V: Is it a real threat to ARM and x86?
Should X86 and ARM feel threatened?

For the past 20 years, there have been only two giants fighting for market dominance over the rest of the market for computer architecture types: laptops and desktops. Typically, since their inception, they have been x86 architecture-based, whereas nearly the entire world's smartphones are based on ARM architecture. Although Qualcomm and Microsoft's foray into the Windows on ARM operating system, specifically designed for the ARM architecture, has recently garnered more attention in the laptop space, the new kid on the block, RISC-V, is also gaining momentum.
