eTeknix posted a review on the Zotac GTX 1660 SUPER TwinFan
A quote from the article:
The SUPERs are coming, that seems to be the theme for 2019! Nvidia may have already released an impressive range of graphics cards this year. However, they’ve been pretty swift to follow them up with SUPER variants that are even faster! Now, we already loved the Zotac GTX 1660 Twin Fan (non-super) when it launched about 8 months ago. While basically none of the GPU core its self has changed, we do see this card move from GDDR5 to GDDR6 memory over the same 192-bit memory bus. Most of the new SUPER cards will also come with an improved factory overclock too.Zotac GTX 1660 SUPER TwinFan Review
