I agree, but from what I have seen they also perform poorly against collab. A 1660 Ti 4gb RAM laptop gpu, runs about as fast as Collab CPU does. [1]
I have not been able to find how the RTX 2080 Super (Laptop) and upcoming RTX 3080 (Laptop) compares to Collab. The 3080 has over 3x as many cores as the 1660 Ti.
