At the moment, the closest thing AMD has to efficiency cores is Zen 4c - and it's really not an eco core in the traditional sense. https://www.techpowerup.com/

  The asymmetrical architecture in the 7950x3D unfortunately results in similar (but less extreme) issues to e-cores. Only one CCD has a big cache, while the other clocks higher. So, it can happen that processes which love the extra cache end up running inefficiently on the higher-clocked smaller-cache cores, or the other way around, where clock-sensitive processes are throttled by running on the 3d cache cores.
