Micro Magic in Sunnyvale, California, has already claimed that its RISC-V processor design was the fastest, but in an interview with eeNews Europe Mark Santoro, CEO of Micro Magic, said the processor core had also been designed so that it can operate down to at least 350mV, near the threshold voltage of the manufacturing process.
This allows a sacrifice in performance to achieve considerable power savings. At 1.1V the RISC-V core operates at a clock frequency of 5.1GHz and consumes about 500mW. At 350mV the core can still be operated at a clock frequency of 1GHz and consumes just 10mW.
