This just seems like explaining the difference between GPU-bound vs CPU-bound scenarios, and pointing out how generational improvements have made a big impact there.
Also, probably something about diminishing returns on the computation needed/accepted for games. Or the other side of the coin, the rising floor (with newer hardware) of what negligible CPU usage can achieve (also something like multiseat or server usage).
EDIT: I should say it both reaffirms how good of a deal I got on a 2700 in mid-2019, and is a good thing to remember on how much better new (Zen) cores are. (probably not upgrading any time soon though and still using a 1050Ti as well, though I don't really need an upgrade anyway)
