I later saw this great talk: https://www.youtube.com/watch?v=Ii_pEXKKYUg … that explains how RISC may achieve CISC-like perf with clever micro-arch tricks. Main concepts is Macro-Fusion in which decoder generates a single uOp for multiple MacroOps & CISC having both 2 and 4 bytes instructions.https://twitter.com/Liran_Alon/status/1223215852146786305 …

It would've been great to see a technical paper comparing x86, ARM & RISC-V and explicitly calling out the advantages and disadvantages of each and the various factors and tradeoff decisions made to reach to these specific ISA designs. Otherwise, it's just handwaving discussions.
