On PC, using a comparable CPU to those Jaguar CPUs would produce even worse results than this in this section. Before upgrading to 3700X, I had an i5-3330 (a CPU that was roughly 2x faster than the PS4 CPU due to its high clock speed and vastly superior IPC) which would at times suffer from long pauses, hitches & stutters in Saint Denis. The kind of stutters and long pauses were simply nowhere to be found on PS4. Sure, there were frame-rate dips as seen above, but never experienced hard pauses on the PS4 version of this game. And I have put countless hours on both console and PC versions.
If you had a comparable GPU to PS4 from 2013/14 like the 7850/7870, then you'd have stutters related to VRAM limitation (on top of having CPU-related stutters) forcing you to use lower quality textures whereas on PS4/XB1 it's equivalent to PC's Ultra textures.
Consoles have a very thin layer of API, less OS, and driver overhead thus requiring less CPU grunt than a comparable PC. That's what John Carmack meant to say when he said: "a console will deliver twice the perf of a PC" back in 2014. These days the tools and the APIs on PC have indeed gotten better and devs are able to extract a lot of perf out of PC hardware as they do on consoles but to some extent, consoles do perform more efficiently still.
