RVA23 vs ARMv9 a Small Experiment
Summary
The article documents a small benchmark comparing RVA22, RVA23 (RISC-V) and ARMv9 using real compiler toolchains to measure static binary size, dynamic instruction bytes, and micro-ops. It concludes that RISC-V can offer smaller code sizes and different instruction-to-uop behavior compared to ARM, with results influenced by SIMD absence and RVV support; GEM5/QEMU results are indicative but not fully portable across environments.
