Question: how much is the A510 optimized for energy efficiency vs. optimized for die size? AnandTech tech did some comparison where the Apple's E-cores are several times more performant than A55 while consuming only slightly more power, and I'm curious if this discrepancy could be explained by different optimization target. If this is not it, could you speculate on what are the reasons for the discrepancy? (I assume A55 is not different enough from A510 to render this question obsolete)
