power/battery usage on risc-v vs arm64?
question is, has anyone any information what is battery or power usage on risc-v cpu compared to arm64 cpu? i am thinking about possible future devices with risc-v. maybe simple cellphone. i know they're not going to happen for short term though.

I'm not sure, but:
The Similarities of RISC-V and ARM:
- Both the RISC-V and ARM are basically RISC (Reduced Instruction Set Computer).
- Both the RISC-V and ARM use the load-store architecture. It means that data is loaded from memory, processed in the CPU, and then returned to memory.
- Both the RISC-V and ARM support 32-bit or 64-bit instruction sets.
- RISC-V is an open-source architecture, whereas ARM is proprietary.
- RISC-V support is minimal, whereas ARM support is extensive.
- RISC-V ‘s endianness is little endian, but ARM’s endianness is bi-endian.
