After the launch of their new mainstream GeForce GTX 1660 Ti graphics card, NVIDIA will now be introducing more price effective graphics cards based on the Turing GPU architecture under the GeForce 16 series family. The new family will be based on the Turing GPU architecture, featuring the same shader enhancements while excluding the RTX feature set such as Ray Tracing and DLSS.

The latest report comes from DigiTimes which states that NVIDIA would be introducing their new GeForce 16 series cards in the coming months. The two cards would include the GeForce GTX 1660 and the GeForce GTX 1650. Both graphics cards are based on the Turing GPU architecture and are more similar to the recently introduced GeForce GTX 1660 Ti than their Turing based RTX siblings.
