But is there any article / papers / field of study that explores the theoretical maximum of various architectures, given infinite resources? Do they begin to converge, such that a highly optimized Arm looks similar to a highly optimized RISC-V core? If we are near / past the point of diminishing returns for x86, how mathematically rigorous is our proof of that?
