The best estimate so far is the "efficiency" cores cost you 15-20% over the performance cores. I think it was Dan Moren from Six Colors who said on a podcast that rendering an 80GB 4K video on a MacBook Air took about 205% of the battery and more than 100% of the battery on a Intel MacBook Pro. And the Air was much faster. Not sure what podcast it was, however. Also, the MacBook Air M1 is faster emulating/translating Intel code that the Intel chips running the code natively. -- "If it's a hobby to us and a job to you, why are you doing such a shoddy job?" - Linus Torvalds to Microsoft
