RVA23 Ends Speculation’s Monopoly in RISC-V CPUs
What happened
The RISC-V RVA23 profile mandates the Vector Extension (RVV), shifting performance scaling from speculative execution to explicit vector parallelism. This architectural change enables simpler, more deterministic scalar cores while maintaining throughput via mandatory vector units. 利多: Long-term potential for cost/power efficiency in certain compute segments; no immediate supply or price impact.
