Area is more like 4 P-core ~= 12 E-core. For AMD, zen 3 core is about double the size of E-Core, but also double the performance. So there won't be area efficiency for AMD to implement E-CoresNot sure I follow. I thought 2 E cores ~= one P cores, yes ? (in performance, not power)
Are you saying one P-core ~= 4 E cores in power ?
