Vintage Titanium to New Carbon bike?

Hello - I just want to gather opinions on if you would see any noticeable differences going from an old race bike to a new one I'm considering purchasing. Will be using for some sprint tris and weekend rides up to 40 miles. I'm leaning towards not a ton, but I don't know very much.

Old Bike - 1996 GT Edge Titanium with Dura Ace components - 19.8 lbs

New (maybe) bike - Canyon Endurace CF 7.0 with 105 components - 17.8 lbs

Thanks!
