Nvidia is preparing new Turning-Based mid-range GPU which will be named the GeForce GTX 1660 Ti, It is the first GPU in market with Turing cores under GTX brand. These GPU’s could offer tensor cores which are needed to accelerate DLS. It comes with higher bandwidth than GTX 1060 equipped with GDDR6 14GBPS on 12nm. New SKU would feature 1536 CUDA cores, 6GB of DDR6 and 192-bit memory interface. TU116 is significantly smaller chip than the TU106 that means GTX 1160Ti will be slower than RTX 2060, by looking at specs it seems like this card would go neck to neck with GTX 1070 at $300 price-point which is nice deal i believe as RX 590 is available for $260 USD.
The rumour stated that there is no launch-date available and expected to release in future.
