Most RISC-V processors use really old node sizes. Even Raspberry Pi is on 28nm. To be more efficient and complete with mainstream processors a move to 10/12nm

Most RISC-V processors use really old node sizes. Even Raspberry Pi is on 28nm.
To be more efficient and complete with mainstream processors a move to 10/12nm is required.
- rwmj 6y agoI think everyone is well aware of that, but unless you're making and able to sell millions of boards and have hundreds of millions in cash flow, there's no real path to using 10nm or smaller nodes. FWIW AllWinner are currently manufacturing 5 million RISC-V chips (with TSMC IIRC). I don't know what node they are using.
- tyingq 6y agoAllWinner's XuanTie 906 RISCV chip is supposedly 22nm. https://www.cnx-software.com/2020/11/09/xuantie-c906-based-allwinner-risc-v-processor-to-power-12-linux-sbcs/ https://www.cnx-software.com/2020/11/09/xuantie-c906-based-a...

- akmittal 6y agoRaspberry Pi is sold in millions but still on 28nm
- CameronNemo 6y agoI guess if you can spring for smaller node sizes, you can spring for ARM licensing too.
