No need for a benchmark, wrapped Chromium is not going to beat Chromium. The curious thing is this urge to lie: a focused UI for Chromium is a valid project, why wrap it in deception and dishonesty?
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.
Or is it private?
I've heard good things about this extension (but use at your own risk, I don't install extensions besides uBlock myself):

You will then have to restart Chrome and enable the feature in settings.
