Sure it can. A chromium browser has an arbitrary number of chromium processes (e.g tabs). The root process quickly becomes irrelevant performance wise for average users.

Even if you have the simplest tab unloading strategy (like Tab suspender) built in, you'd beat Chrome. But, unloading tabs isn't a safe thing to do in web-standard browsers but fine in niche consumer ones.

Its not really word-smithing either, in all practical ways that matter to the end user, something like tab suspension makes it a much more efficient browser. Even if the JS/rendering (engine) bits are the same speed.

Although, to be fair, I'm not sure if Min does this, the chromium browser I made does.
