JensensStapler··on SiFive P550 Core: High-Performance RISC-V Processor
Merchant ARM server is mostly dead unfortunately. Hyperscalers like AWS are making their own SoCs in house however. Amazona acquired Annapurna labs for that purpose.

Personally I see there being more market overlap between ARM and the P550 core however. Samsung, Qualcomm, Renesas are all planning to bring RISC-V cores to market. With performance between A75 and A76, I could see the P550 being a pretty major disruptor. We already know some RISC-V chips are gaining traction in embedded, IoT, RF, micro-controllers, etc. Automotive looks like the next big market for RISC-V to me.

No, the area numbers quoted are for TSMC N7. You can look up comparable A75 die area numbers for N7 as well. A Cortex A76 on TSMC N7 takes up 1.27mm with L2 included. A P550 takes up 0.38mm.

The P550 core in the title is actually a 3 way issue OOO core with near A76 performance, but fair point on the dev boards. Hopefully Intel's dev board or some alternative will provide a lower cost option.
