cuDF is the most impressive DataFrame implementation I've seen and have been recommending for years. The API is exceptionally close to Pandas (just a couple of different function arguments here and there), much more so than PyArrow or Modin. Throughput and energy efficiency were often 10x that of PyArrow running on a comparable TDP SotA CPU 2 years ago [1].
