This is pretty significant. The RISC workstation and server markets were destroyed in the 90s by intel’s way less performant x86 parts was intel were a generation ahead in Fabs (so getting better performance and yield despite the bad architecture) -earning enough money to fund the R&D of CPUs and the $B for the next fab iteration, and spreading those NRE and CAPEX costs across consumer, business and server lines. All those advantages are now gone.
