Based on what I’ve been seeing I think a Ryzen 5 4600H or Ryzen 7 4800H paired with a GTX 1660 Ti is the best option currently for laptops.
HOWEVER, good luck finding a good one. Apparently MSI’s laptops are trash, ASUS’s laptops are trash in the thermals department, I have yet to see a HP Omen or Lenovo Legion, and Acer has only one. Which is sad because the Ryzen Mobile chips are very good.
