I don't think it's e-cores so much as a Zen 5 version of the Zen 4c cores. So smaller L3 (the 4c has half the L3 that the Zen 4 has) and slower clocks. But the compact cores are half of the size of the regular cores and about 75% of the power. The key point is that the cores are otherwise the same so you don't have the weird intel situation where the e-cores don't support the same instructions as the p-cores.
