Any references to browser documentation? Would be intetesting to understand differences in technical implementation .
I can just assume, that browser does full page refresh it makes it looks smoother, but not much gain in performance.
With turbolinks you can refresh only part of the page, leaving other things intact (or with minimum changes).
Browsers tends to get better and better at rendering pages smoothly. But one thing turbolinks (and such) will always improve is load time.
When you fetch twice the same resource (css, js ...), your browser reload from local cache (disk), but it reloads it anyway (plus parsing and such).
Even better, some lib will preload the target page when the user hover the link. It take a minimum of 100ms for someone to click a link, these time is used to load the next page.
Ever asked yourself why Dev.to is so fast to load ? Take a look at your debugger's network panel and hover any link.
That makes a lot of sense, it's less about the flash to white of a page navigation and more about performance and responsiveness of the page.
