But here is some information that I personally find price sensitive stolen from the Renesas thread:
“RISC-V in the automotive and IoT embedded market
The served addressable market (SAM) for automotive RISC-V was around 4 million cores in 2020. By the end of next year it could grow to around 150 million cores and even to 2.9 billion cores by 2025. That's the prediction of Semico Research augurs in their latest report, "RISC-V Market: Momentum Building," updated in February 2021. This focuses on four semiconductor devices where RISC-V cores lend themselves to use: Advanced Performance Multicore SoC, Value Multicore SoC, Basic SoCs and FPGAs.
The cooperation between Renesas Electronics and SiFive shows that these figures are not made up out of thin air: The two companies want to develop "high-end RISC-V solutions for automotive applications". As part of the "strategic partnership", SiFive is licensing its RISC-V core IP portfolio to Renesas.”
