The global semiconductor landscape has reached a historic inflection point as the open-source RISC-V architecture officially secured 25% market penetration this month, signaling the end of the long-standing architectural monopoly held by proprietary giants. This milestone, verified by industry analysts in late December 2025, marks a seismic shift in how the world’s most advanced hardware is designed, licensed, and deployed. Driven by a collective industry push for “architectural sovereignty,” RISC-V has evolved from an academic experiment into the cornerstone of the next generation of computing.
Mostly Qualcomm’s cpus for automotive and enterprise servers and Meta’s (Facebook) custom AI chips.
For consumer products is still an hobbist with Linux exclusive.
SteamDeck 2 will still have an ARM.
Of what little I know, ARM core designs should be relatively easy to repurpose for RISC-V ISA, once the set of extensions normally used becomes certain. Most of the work being in decoders.
So it just comes down to a still new and not entirely stable ISA. Like with network protocols.
