But even if the big cores do 2/3rds, the little cores are only taking up 20% of the CPU core die area, so performance/area/w is likely much better. And I'm not so sure the big cores are doing 2/3rds. They certainly are not getting two threads with each thread as good as the single thread Gracemounts clk for clk. So the question is who much different are the clocks? I'd say 60:40 might be closer. In which case 80% of the core die area is doing 60% of the work, and 20% is doing the other 40%.

Remember the hint that Intel might roll out a big.LITTLE device with like 32 little cores? I thought that was an error in the article, but I can see how that might be an OK design.
