Two times four SMT4 cores means as much as 32 hardware threads.

I'm (positively) surprised myself that a 4-core POWER9 seems to exist, but I find it unlikely that the Raptor people are confusing cores and threads (per core).

Weren't you put off by this just moments ago? ;-)

Considering I'm surprised by the quad-core variant, I find it extremely unlikely that IBM produces something like a single-core POWER9.
