I read the EEtimes article[1] and find it surprising that they claim to beat the Apple M1. They don't say how, though...

It's pretty normal for lower complexity cores to be more power efficient than higher complexity cores. Many structures in a processor scale as N^2 with width in terms of both transistors and power usage.

Their math is off by a factor of 250 x, thus, their claim us strange because they didn't check their math, before publishing wrong figures!
