The former defender and current pundit was impressed with a specific aspect of both sides.
Indeed, Stoke visited the Liberty Stadium and provided a decent - if not all-too-thrilling - contest.
And Ferdinand likes the speed possessed within both club's line-ups, something Stoke especially haven't exactly been known for over the years.
First off, Ferdinand took to Twitter to praise the likes of Jefferson Montero, Modou Barrow and Andre Ayew of Swansea, suggesting they have pace 'to burn.'
When prompted by a follower to say the same about Stoke, meanwhile, he duly obliged...
Pace to burn in Swansea attacking line!! Montero.. Barrow.. Ayew— Rio Ferdinand (@rioferdy5) October 19, 2015
@rioferdy5 Stoke's isn't exactly slow either Rio. Arnie...Bojan...Shaqiri, plenty of pace there too.— Daniel Houldey (@Dan_Houldey90) October 19, 2015
Stoke picked up a vital third win in a row at Swansea, with an early Bojan penalty setting the tone for an encounter during which they defended astutely throughout.
Next up for Mark Hughes' men is a home clash against Watford, while Swansea travel to Aston Villa. There, Garry Monk will hope for more from his pacey players...
