You think Meta bought Rivos to work on embedded?
You think the Alibaba C930 CPU is for embedded? 15 SPECint2006 / GHz
Or that the Tenstorrent Ascaclon will be? 18 SPECint2006 / GHz
Even the SpacemiT K3 has better AI performance than an Apple Silicon M4.
And RISC-V chips released this year are 2-4 times faster than last year. RISC-V is not the fastest ISA but it is improving the fastest.
With so many companies backing RISC-V, why would I bet against it?
