The NVIDIA GeForce GTX 1660 SUPER is on its way and will arrive before the end of the month, according to confirmation that Videocardz has received from its sources. The new GPU will sit between the GTX 1660 and GTX 1660 Ti in NVIDIA's product stack, with its pricing reflecting that. Oddly, the GTX 1660 SUPER will outdo the GTX 1660 Ti in some areas, while retaining elements of the GTX 1660 too.
