Maybe lighter? Can you find out for sure? Are you able to weigh your present wheels and get a weight on the new wheels?

Cartridge bearings might be an upgrade that isn't a given. Shimano's top of the line Dura Ace wheels have loose bearings.

It doesn't make sense to replace cheap, heavy wheels with cheap, heavy wheels. Unless the bearings on the current wheels are shot or the wheels are wider or you just want to change the look then the best thing to do might be nothing.
