Dunno about minimum, but 10^3 refreshes/s over 10^15 sites (~kBit)
(10^21 fat ops/s, including according communication crossection)
could probably do it. 

An off-shelf PC can encode some 10^6 sites, at maybe 10^-3 refreshes/s.

You can't understand intelligence by what is commonly considered
"understanding". This doesn't mean you can't recreate intelligence or
improve upon intelligence.

It's likely.

Let's say I'll give you full inspection and modification powers
to the hardware in your head. To what degree do you expect to
"understand" it and to do "optimizations" of it other than tweaking
fundamental parameters of the substrate?

I do think we do.

Intelligence is the sum of such activities. In order to compete
with humans across the board you need all of it.

Turing is dead. Wrong.

Turing's test is distinctly dated. Consider my metric above.
