This is what the official nomenclature seems to be:

All the branding I've ever seen in the modern world calls it POWER,
and AIUI the PowerPC branding was abandoned like 15 years ago.

The debian wiki page even says

but wikipedia tells me the last product from this line came out in 2006,
which is pushing two decades by now. Even then, apparently
"PowerPC is largely based on the earlier IBM POWER architecture"
so it's the same thing.

Maybe when Apple had a choke-hold on the millennial mind a calling it
"PowerPC" could've made sense, but through a modern lens PowerPC,
to the extent it exists at all, is just a derivative of POWER I think

Best,
