What's the most efficient processor as far as area is concerned?

Generally speaking you're lucky if your average Ars/Anandtech/whatever article bothers to mention the aggregate number of transistors in a SoC, or its overall area.

Can anyone make a stab at breaking down how many transistors AMD/Apple/ARM/Intel require for a core, making a direct comparison possible - ie exclude ISA cruft, exclude SMT, memory controllers, GPU, NPU, or anything else non-CPU ?

Is it wrong to focus solely on transistor count - maybe you need to take between-transistor wire lengths into account as well, and maybe some features are expensive in that regard ?

How much in percentage terms does SMT cost (more, or less, than what it adds in performance) ?

It would probably be fair to make allowances for pipeline length.

Could you put 256 A55 cores and a few A77s on a 100 mm2 7nm chip, maybe make Threadripper look a bit silly ?
