All theoretical differences maintaining a fairly high power constant while messing around with weight using some ideal computed system, and with long, high power climbs.
You could lose the same 20 pounds by trading in your 35 pound bike for a 15 pound bike. And, limiting tools and gear you're carrying, as well as sending your four pints of water to the top of the hill with your Sherpa.
