See, for example:

https://everymac.com/systems/apple/powermac_g5/specs/powermac_g5_quad_2.5.html

There was: two sockets with 2 cores each. Apple Marketing
called this configuration "Quad Core": It is a misnomer
or is at least misleading given what their "Dual Core"
vs "dual processor" wording referred to. I frequently
reference the "Quad Core" as "so-called 'Quad Core'"
for the "PowerPC 970MP (G5) x2" configuration.

I have access to two of these and top and other things
show all 4 "cpus" (in FreeBSD terminology).
