Apparently I am super wrong here. ARM has made serious inroads here as well.

I think that ARM's willingness to allow their IP to be customized for their clients needs has really given them a lot of competitive advantages.

That might be where Intel and AMD failed. With the hindsight watching ARM gobble up a number of sectors, Intel and AMD should have allowed their IP to be customized which may have slowed ARM's advance. Competition is good though. If this continues, AMD and Intel may have to merge. I wonder how RISCV is going to shake things up? Intel and AMD should build RISCV chips and chance ARM. That'll form a nice loop.

Right now RISC-V is ultra slow in all implementations I've seen. Like 30x slower than a top of the line Apple Mx series CPU. Maybe there is a high performing RISC-V chip out there but I haven't yet run into one.

RISC-V benchmarks: https://browser.geekbench.com/search?q=RISC-V. Compare to an Apple M4 benchmark: https://browser.geekbench.com/v6/cpu/8224953

That said, RISC-V is good for embedded applications where raw performance isn't a factor. I think no other markets are yet accessible to RISC-V chips until their performance massively improves.
