That isn't how CPU design works. The microarchitecture is what matters and you can use the same techniques as x86 uses today to get good performance. Just because there is a new ISA does not mean a company cannot design a modern CPU. For example, the Vision Star Five is uses an in order CPU core that is competitive with the out of order A72 core. The performance gap on day one is much smaller. It also has UEFI support and opensource GPU drivers for Power VR are in development by imagination, so the software support will also quickly catch up or surpass ARM SBCs. The same will happen in the server market. Nobody who works on a RISCV server chip has to wait for ARM to deliver a CPU core that doesn't suck.
