NVIDIA's AIB partners are working on numerous custom variants for the upcoming GeForce GTX 1660 SUPER graphics cards. A large variety of these models have either been listed by retailers or leaked out (via 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 of the graphics card will be maintained at 1530 MHz base and 1785 MHz boost. The major change to the graphics card would be the memory design.
