RISC-V CPU Performance Up 8x In Five Years: SiFive HiFive Unmatched To SpacemiT K3

Recently I published some initial SpacemiT K3 benchmarks for that first-to-market RISC-V RVA23 SoC with the K3 Pico-ITX mini computer. In there was a comparison against modern Intel Core Ultra and AMD Ryzen desktop CPUs along with the likes of the Raspberry Pi 5, Loongson 3B6000, and SiFive HiFive Premier. For those curious about the longer-term RISC-V performance, here is a look at how far the RISC-V hardware performance has come compared to the SiFive HiFive Unmatched RISC-V board from five years ago.

Why this matters
Why now

The proliferation of RISC-V across various applications and the increasing maturation of its ecosystem are yielding significant performance gains making it a viable alternative to established architectures.

Why it’s important

Rapid performance improvements in RISC-V indicate its growing competitiveness as a foundational technology for computing, potentially disrupting existing market structures and supply chains.

What changes

RISC-V is no longer a niche or academic pursuit but a rapidly evolving architecture approaching performance parity in certain segments, broadening its appeal and adoption.

Winners
  • · RISC-V ecosystem
  • · Open-source hardware developers
  • · Geopolitical actors seeking compute independence
  • · Embedded systems developers
Losers
  • · Proprietary CPU architectures (x86, ARM licensees)
  • · Companies heavily invested in legacy instruction sets
Second-order effects
Direct

RISC-V will gain market share in segments currently dominated by ARM and x86, particularly in embedded, edge AI, and potentially server markets.

Second

Increased competition could drive down costs and accelerate innovation across the semiconductor industry, benefiting consumers and businesses.

Third

Nations seeking technological sovereignty could increasingly adopt RISC-V for critical infrastructure, diminishing reliance on external chip suppliers and IP.
