What it is

Chris Celio of UC Berkeley compares the RISC-V, ARM and x86 instruction sets, with quantitative data on instruction counts and code density. It examines how the compressed extension fares against Thumb and x86.

Why Hacker News recommends it

Cited as primary-source evidence that RISC-V code density is competitive with or better than ARM and x86.
