There's a website:
https://www.bicyclerollingresistance.com/ that purports to show the rolling resistance and other parameters of various tires. You can easily compare any two or three sets of tires.
Short answer: GP5000's have remarkably low rolling resistance -- by about five watts. Is five watts noticeable or important? That's up to you to decide. I can think of any number of scenarios where five watts is a meaningless improvement; likewise, I can envision scenarios where five watts is important.
