TBH, these specs make the GTX 1660 non-super looks like a stupid buying decision. With the memory limits of that card, the fewer SMs on the 1650 Super shouldn't matter. That said ROPs could limit things. Hard to know.
the 1650 Super is going to be faster than a GTX 1060 6gb , which is a massive improvement. But as always, Nvidia will F*ck it up with very high prices.
