Nordic combines Arm and RISC-V for 'remarkable' EEMBC benchmarks

Nordic Semiconductor has announced EEMBC benchmarks for its forthcoming multi-protocol nRF54H20 wireless microcontroller, which combines multiple Arm Cortex-M33 processors and multiple RISC-V coprocessors "optimised for specific types of workloads", it said, adding that developers will be able to dynamically change between configurations for processing ability or energy efficiency.

Configured for high processing efficiency, it got a ULPMark-CM score of 170 with 515 CoreMark (CoreMark is the workload for ULPMark-CM). Configured for high performance, it scored 132 ULPMark-CM and 1290 CoreMark. It also scored 165 ULPMark-CM at 3.0V (515 CoreMark) in the fixed voltage category.

These three results mean that the IC tops each category (out of 12 MCUs) for the benchmark – but a small note of caution: these are in-house results (as are most of the results in this EEMBC table), not certified results tested in the EEMBC labs.

"The results are remarkable," said Nordic CTO Svein-Egil Nielsen. "nRF54H20 is our fourth-generation product series. With it, we aim to redefine processing power and energy efficiency. We're eager to see what customers can create with these wireless solutions."

Nordic is being unusually secretive about this family of ICs and is only releasing information in tiny drips – for example, the number of cores remains undisclosed at the time of writing.
