The most-sold Nutribullet has a power of about 500-600W, Vitamix is more at 1500W. re:Mix in at 1000W, part of the category of high-performance blenders.

However, power is not the whole story. As an example: in this video, re:Mix is competing against the more-powerful Phillips blender with 1.200W. re:Mix made a creamy better peanut butter 3 times faster, due to other factors such as glass shape and volume.
