What do die shrinks have to do with ISA performance? Also, there are no RISC-V CPUs available that match the latest X86 or ARM CPUs. Even then, the ISA chosen doesn't have much to do with the performance of CPUs (at least, when comparing major ISAs like X86, ARM and RISC-V).


Smaller nodes (generally) translate to lower power consumption, more transistor density, and faster transistor switching speeds.

It allows for an architecture to deepen pipelines, add registers, add cache, and pull off tricks like SMT.

That's somewhat my point, the limiting factor for ISA performance is the physics surrounding the transistors.
