NVIDIA is soon going to introduce their GeForce GTX 1660 SUPER series graphics cards which are positioned against the mainstream Navi lineup arriving soon. The NVIDIA GTX 1660 SUPER series has seen various leaks and the latest includes pictures of ZOTAC's custom models that have been leaked by Videocardz.

In our previous report, we talked about how the NVIDIA GeForce GTX 1660 SUPER would offer the newer GDDR6 memory interface while retaining the rest of the specifications. In terms of specs, the GeForce GTX 1660 SUPER would utilize the TU116-300 die, same as the existing GeForce GTX 1660. It would feature the same core config of 1408 CUDA cores, 80 TMUs, and 48 ROPs. The clock speeds are not mentioned but those can get a slight bump. The major change to the graphics card would be the memory design.
