I think RISC-V, without some additional extension(s) and maybe some rework, will have trouble scaling the levels necessary to be competitive performance-wise with smartphone devices or data centers the way ARM v8 is. Erin Shepherd did a good write-up why: https://gist.github.com/erincandescent/8a10eeeea1918ee4f9d9982f7618ef68 https://gist.github.com/erincandescent/8a10eeeea1918ee4f9d99... David Chisnall’s critique is also worth a read: https://lobste.rs/s/icegvf/will_risc_v_revolutionize_computing#c_8wbb6t https://lobste.rs/s/icegvf/will_risc_v_revolutionize_computi... With that said for applications that are sensitive to power or transistor counts it wouldn’t surprise me if it takes over the low to midrange MCU market 10 years from now.
