NVIDIA's AIB partners are silently adding a new GeForce GTX 1650 graphics card to their inventory known as the GeForce GTX 1650 Ultra. The new graphics card is based on the Turing architecture & features the TU106 core which is one of the reasons it is referred to as the Ultra edition.
Note - The 6 GB listing could be an error in GALAX's database as it lists down the GTX 1660 Ultra model. However, the rest of the specifications as listed are different from the GTX 1650 Ultra.
