The nVidia GTX 1660 Ti was launched on February 22, 2018. With a MSRP of $279, the new card is launching at $30 above the GTX 1060 6GB it replaces.

The nVidia marketing people are calling it 16: The New Supercharger. The TU116 is Turing architecture with the rest of the fluff removed. The TU116 adds a new feature of FP16 beside the FP32 and INT32 registers to add a third execution path. FP16 is more widely seen in mobile graphics so this seems like a prudent move for game developers.
The 1536 CUDA cores are enough for 1920×1080 gaming with all contemporary games. The 6GB of VRAM is enough for MSAA etc but excessive antialiasing can bog a card down fast.
When compared to the Pascal-based GTX 1060, the 1660 Ti die is 42% larger, but only packs 20% more CUDA cores. These TU116 cores have been upgraded and are now much wider by comparison. This makes the GTX 1660 Ti somewhere near the GTX 1070 or GTX 1070 Ti for performance with quite some differences between games.
The short 5.7″ length means the GTX 1660 Ti can fit a µATX chassis easily. More and more are using smaller sized machines, but there are many with more room to handle dual fan cards. Dual fan versions are available for those who want them.
We expect AMD to respond with price changes to realign their products in the marketplace. We have noticed the average selling price for the RX Vega 56 has been lowered which has resulted in the card being sold out with some stores.
For $280 we would have like the GPU to get 256-bit memory based and offer a full 8GB of VRAM so that it would be viable for a few years with 1080p gaming. nVidia did not want to cut into RTX sales with a stronger card. Rival AMD cards at this price point offer 256-bit memory and a few more cores.
Speculation that additional cards such as a binned TU116 could be launched as a GTX 1660 at some time or another. A different GPU for a lower price point is also speculated for the fall shopping season.
The recent mess at TSMC will likely slow a new GPU launch for a few months. TSMC will probably get their 14nm line back up and running in a few weeks after they get some new material supplies and clean up the line. TSMC is close to volume production with their 7nm line and it may be coming into production for a summer launch of new products for several customers.
